* 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.

This appears to have been broken since the introduction of mouse
assignments :-/
This commit adds Pane::is_alt_screen_active so that the gui layer
can tell whether the alt screen is active, and allow passing down
the event.

TL;DR: on unix, or if bracketed paste is on, then we paste with
unix newlines. If on windows && !bracketed paste then with CRLF.
See explanation in the code for more context.

Since we no longer have our fallback Software renderer (only mesa),
remove what has become an empty variant and hoist the GL state up
into RenderState, holding Option<RenderState> in the window.
This persuades the CI to install both the arm and intel flavors
of the rust toolchain on macOS, and the deploy script to generate
a universal binary.
* need big sur to build for M1
* Use cross-compilation compatible mlua from my fork for now
AppImage passes fd 1023 opened on the mount point directory.
If we close this prior to exec, some magic in appimage decides
to unmount the fuse mount right before we're about to exec
the wezterm-gui binary from the appimage.
So, don't close stray fds when the cli spawns the gui when
we're an appimage.

It's been replaced with an opaque termwiz error type instead.
This is a bit of a more conservative approach than that in (refs: #407)
and has less of an impact on the surrounding code, which appeals to
me from a maintenance perspective.

wezterm sets a more restrictive umask (`0o077`) by default so that any files
that it creates (eg: unix domain socket, log files) are more secure
by default.
However, some environments rely on the more general default of (`0o022`)
without checking that it is set.
This matters because programs spawned by wezterm inherit its more
restricted umask.
I hadn't noticed this because I've had `umask 022` in my shell RC files
since sometime in the 1990's.
This commit adds some plumbing to the pty layer to specify an optional
umask for the child process, and some more to our umask saver helper
so that any thread can determine the saved umask without needing a
reference to the saver itself, which may be in a different crate.
The logic in the config crate has been adjusted to connect the saved
value to the default command builder arguments.
The net result of this is that running `wezterm -n start bash -- --norc`
and typing `umask` in the resultant window now prints `0022`.

You can install this into your $TERMINFO directory (default is
`$HOME/.terminfo`) by running:
`tic -x wezterm.terminfo`
from this data directory.
Once installed, you can set `TERM=wezterm`.

This allows us to support the kitty style underline sequence,
or the : separated form of the true color escape sequences.
