It's not perfect; this only handles the case where you move down
into the terminal. I couldn't easily make the same thing happen
when moving the mouse up or left outside of the window. It's
probably fixable but this is better than it was.

We weren't fixing up the active tab position correctly after removing
a tab. I think this bug crept in around the ActivateLastTab changes.
We now try harder to set active idx back to the tab that was active
prior to the remove, and ensure that we set the active index to
something within range if it was the active tab that was removed.

Now that all platforms know whether the system fallbacks
covered the requested glyph range, it is reasonable to
restore the configuration error window to advise the user

The repro scenario for this case was:
* open GNU nano
* hit enter twice
* type hello
* move the text cursor to the top line
* double click on hello
* hit enter
Prior to this commit, the selection would remain on the now-blank line
that previously held `hello`.

This replicates `last-window` in tmux. To pull this off, I
deliberately store the last tab whenever I'm activating a new one or
spawning a new one. I had to do this explicitly rather than hooking
set_active, because we end up setting the active tab briefly for some
common operations like moving a tab.
These now operate in terms of logical lines so they deal with
lines that have wrapped outside the viewport better than in
previous releases.

Rust 1.51 allows addressesing a long-standing TODO which was that we
shouldn't need to build a vendored copy of openssl on most sensible unix
systems.
We do require a vendored copy on macOS and Windows, but due to the way
that Cargo's feature resolver worked, it wasn't possible for this
requirement to be respected.
Rust 1.51 introduces `resolver="2"` which can deal with this feature
resolution!
https://doc.rust-lang.org/nightly/cargo/reference/features.html#feature-resolver-version-2
The upshot of this is that building wezterm on real unix systems that
are not macos will now link against the system libssl, resulting in both
a shorter compile time and less headaches arising from having a slightly
different openssl used by wezterm than the rest of the system.

terminus-bold.otb reports 0 height!
Detect and force that case to go through the bitmap strike loading
code path.
Improve the size selection heuristic for bitmap strikes: previously,
we would just pick the largest bitmap and allow it to be scaled down,
which was OK for emoji fonts that just had 128px square glyphs, but
is not ok for pre-rendered pixel strikes like terminus.
Note that IncreaseFontSize works in terms of percentages only,
so using a font like this may have "gaps" when ctrl-+ or - to change
the font size.

This is first draft; the animation rate is currently tied
to the cursor_blink_rate setting, so if the gif has frames that
are intended to display more frequently than that, they will
animate more slowly.
Animation is only carried out while the window has focus.
Animation increases the load on the GPU and thus uses more power.
It's kinda fun to stick one of these animated pixel gifs in the background:

This commit expands on the prior commits to introduce the concept
of per-window configuration overrides.
Each TermWindow maintains json compatible object value holding
a map of config key -> config value overrides.
When the window notices that the config has changed, the config
file is loaded, the CLI overrides (if any) are applied, and then
finally the per-window overrides, before attempting to coerce
the resultant lua value into a Config object.
This mechanism has some important constraints:
* Only data can be assigned to the overrides. Closures or special
lua userdata object handles are not permitted. This is because
the lifetime of those objects is tied to the lua context in which
they were parsed, which doesn't really exist in the context of
the window.
* Only simple keys are supported for the per-window overrides.
That means that trying to override a very specific field of
a deeply structured value (eg: something like `font_rules[1].italic = false`
isn't able to be expressed in this scheme. Instead, you would
need to assign the entire `font_rules` key. I don't anticipate
this being a common desire at this time; if more advance manipulations
are required, then I have some thoughts on an event where arbitrary
lua modifications can be applied.
The implementation details are fairly straight-forward, but in testing
the two examplary use cases I noticed that some hangovers from
supporting overrides for a couple of font related options meant that the
window-specific config wasn't being honored. I've removed the code that
handled those overrides in favor of the newer more general CLI option
override support, and threaded the config through to the font code.

`wezterm`, `wezterm-gui` and `wezterm-mux-server` now all support
a new `--config name=value` CLI option that can be specified
multiple times to supply config overrides.
Since there isn't a simple, direct way to update arbitrary fields
of a struct in Rust (there's no runtime reflection), we do this
work in lua.
The config file returns a config table. Before that is mapped
to the Rust Config type, we have a new phase that takes each
of the `--config` values and applies it to the config table.
For example, you can think of configuration as working like this
if wezterm is started as `wezterm --config foo="bar"`:
```lua
config = load_config_file();
config.foo = "bar";
return config;
```
The `--config name=value` option is split into `name` and `value`
parts. The name part is literally concatenated with `config` in
the generated lua code, so the name MUST be valid in that context.
The `value` portion is literally inserted verbatim as the rvalue in the
assignment. Not quoting or other processing is done, which means
that you can (and must!) use the same form that you would use in
the config file for the RHS. Strings must be quoted. This allows
you to use more complicated expressions on the right hand side,
such as:
```
wezterm --config 'font=wezterm.font("Fira Code")'
```
The overrides stick for the lifetime of the process; even if
you change the config file and reload, then the value specified
by the override will take precedence.

This is defined as a trait method on Pane (default: false), and has the
obvious transitive equivalent methods in Tab and Window (eg: if all
contained items are `can_close_without_prompting`, then that container
is also `can_close_without_prompting`).
The intent is to avoid bothering the user to confirm closing a window
when the content is not stateful and doesn't warrant it.
For example: the window that is displayed in the event of a
configuration error really shouldn't prompt to the user to confirm
closing it.
All termwiztermtab panes are `can_close_without_prompting==true`
to effect this policy.
In the future, we could teach LocalPane to lookup the session leader
process against a list of "uninteresting" or "stateless" processes
and return an appropriate result (as suggested in
https://github.com/wez/wezterm/issues/280). That functionality
is NOT part of this commit.
`exit_behavior = "Hold"` will keep the pane alive until explicitly
closed. More details in the docs that are part of this commit.

This fixes a longstanding issue under mutter where client side
decorations are in use. The decorations were being drawn too
early in the initialization of the window which could leave them
off-screen and weird. This was masked by a couple of mutter
related bugs with client side decorations.
With these changes I now get sane decorations under mutter,
and the toggle fullscreen action is now enabled as well!

We weren't didn't treat the "No existing hyperlink, No new hyperlink"
case as no change in hyperlink, and were invalidating the window on
every mouse except for those over text with a hyperlink.
Pasting a lot of text could cause a deadlock between writing
to the input side of the pty and consuming the output side.
Making the writer/input side non-blocking resolves this.
Dead key processing respects the
`send_composed_key_when_left_alt_is_pressed` and
`send_composed_key_when_right_alt_is_pressed` options.

CTRL-SHIFT-{C,V} use Clipboard.
{SHIFT,CTRL}-Insert use PrimarySelection.
`CompleteSelection` and `CompleteSelectionOrOpenLinkAtMouseCursor` now

* Adds `CopyTo` and `PasteFrom` assignments that specify the
destination/source.
* Adds `default_clipboard_copy_destination` and `default_paste_source`
config options that specify the default destination/source for
existing `Copy` and `Paste` operations (for @bew)
* Deprecating `PastePrimarySelection` in favor of `PasteFrom`.
* Added `CTRL-Insert` -> `Copy` (for @Babar)
Aside from the new key assignment, these changes shouldn't change
the default behavior, but do make it easier to consider changing
that in a later commit.
They should allow for example:
* Set `default_clipboard_copy_destination = "PrimarySelection"` to
prevent populating the clipboard by default when using the mouse.
* Overriding the CTRL-Insert, CTRL-SHIFT-C to explicitly populate
the clipboard
* Set `default_paste_source = "PrimarySelection"` for middle click
to paste the selection.
* Overriding SHIFT-Insert, CTRL-SHIFT-V to explicitly paste from
the clipboard.

* Add ClearBuffer action
Clears all lines, both visible and those scrolled off the top of the viewport, making the prompt line the new first line and resetting the scrollbar thumb to the full height of the window.
This is the behavior that Hyper / xterm has for clearing the terminal.
* Combine ClearBuffer into ClearScrollback as enum with associated erase mode
Makes it easier to manage the different options of clearing the terminal.
The default is true, which means that adjusting the font size will
cause the window to resize to preserve the number of rows/cols in
the terminal.
When set to false, the window size is preserved and the number of
terminal rows/cols is adjusted instead.

I started this a while ago; it's pretty time consuming to produce
accessible and usable documentation for this sort of stuff, so
this isn't yet complete, but in the interest of avoiding additional
bit-rot, let's get this up.

The heart of this issue was that the resize callbacks have two
layers of state; one in the low level window and one in the application
level window.
On Windows, the system triggers the low level callback prior to
opengl being initialized. Since the application level depends on
the opengl state, there are some code paths where it NOPs and
returns early if opengl isn't yet initialized.
When the system-wide display scaling is set to say 200%, the application
layer can't know the effective DPI of the window it is creating because
it doesn't know which monitor will be used or what its DPI will be.
New windows are created at the default DPI of 96, and we rely on the
resize events to detect the actual DPI and adjust the scaling in
the window.
The early call of the resize callback meant that the low level and
application level size/dpi state was out of sync and the result was
that the window had half as many pixels as it should, but that the
terminal model was still sized as though it had the correct amount
(twice as many as visible). This resulted in the window being too
small for the viewport.
The resolution is simple: we now suppress emitting the resize processing
until opengl has been initialized.
The test scenario for this is:
* Set system scaling to 100%
* Launch wezterm
* Set system scaling to 200%
* Observe that wezterm scales to match
* Press CTRL-SHIFT-N to spawn a new window
* Observe that the new window size matches the other window (previously
this one would be half the size)
While I was looking at this, I noticed that the manifest didn't
match the DPI awareness that we have in the code, so update that.

I've seen a number of people copy and paste the example that runs
`top` and be confused by it, so try to make it a bit clearer how
to get a regular split with a shell inside it.
If a font doesn't have any latin glyphs then we'd compute 0 as the
average width. Later, during rendering, we'd compute an `inf` scaling
factor and then subsequently fail to allocate texture space.
This commit takes the average width from a "random" selection of glyphs
(whatever the first few glyphs in the font may be) to avoid that
situation.
