* infocomplete: Complete filetypes (follow-up)
The first shot of the feature unfortunately completed the *.yaml file
names instead of the included filetypes. This will be corrected with
this follow up.

* Revert "Don't expose Go timers directly to lua"
This reverts commit 4ffc2206ee.
Reason for revert: some plugins happen to use raw Go timers via
time.AfterFunc(), in an unsafe way (without synchronizing their
async code with micro). Let them keep doing that for now, in an
unsafe way but at least without immediate crashes.
Fixes#3209
* Add TODO about Go timers deprecation
`unknown` is a valid value for the `filetype` option (and executing
`set filetype unknown` does what is expected: it forces filetype
autodetection). So let's add `unknown` to the autocomplete suggestions
for `filetype`, along with actual filetypes.
The section says that users may use their own .hdr files for their own
custom syntax files, which is simply not true.
As a matter of fact, .hdr files are an implementation detail that
doesn't need to be mentioned in the user documentation.
Turning `header` patterns into `signature` patterns in all syntax files
was a mistake. The two are different things. In almost all syntax files
those patterns are things like shebangs or <?xml ... ?> or
<!DOCTYPE html5> i.e. things that:
1. can be (and should be) used for detecting the filetype when there is
no `filename` match (and that is actually the purpose of those
patterns, so it's a regression that it doesn't work anymore).
2. should only occur in the first line of the file, not in the first
100 lines or so.
In other words, the old `header` semantics was exactly what was needed
for those filetypes, while the new `signature` semantics makes little
sense for them.
So replace `signature` back with `header` in most syntax files. Keep
`signature` only in C++ and Objective-C syntax files, for which it was
actually introduced.
Replacing header patterns with signature patterns was a mistake, since
both are quite different from each other, and both have their uses. In
fact, this caused a serious regression: for such files as shell scripts
without *.sh extension but with #!/bin/sh inside, filetype detection
does not work at all anymore.
Since both header and signature patterns are useful, reintroduce support
for header patterns while keeping support for signature patterns as well
and make both work nicely together.
Also, unlike in the old implementation (before signatures were
introduced), ensure that filename matches take precedence over header
matches, i.e. if there is at least one filename match found, all header
matches are ignored. This makes the behavior more deterministic and
prevents previously observed issues like #2894 and #3054: wrongly
detected filetypes caused by some overly general header patterns.
Precisely, the new behavior is:
1. if there is at least one filename match, use filename matches only
2. if there are no filename matches, use header matches
3. in both cases, try to use signatures to find the best match among
multiple filename or header matches
Replacing header patterns with signature patterns was a mistake, since
both have their own uses. So restore support for header regex, while
keeping support for signature regex as well.
The original meaning of foundDef was: "we already found the final syntax
definition in a user's custom syntax file". After introducing signatures
its meaning became: "we found some potential syntax definition in a
user's custom syntax file, but we don't know yet if it's the final one".
This makes the code confusing and actually buggy.
At least one bug is that if we found some potential filename matches in
the user's custom syntax files, we don't search for more matches in the
built-in syntax files. Which is wrong: we should keep searching for as
many potential matches as possible, in both user's and built-in syntax
files, to select the best one among them.
Fix that by restoring the original meaning of foundDef and updating the
logic accordingly.
* rtfiles: Initialize all-/realFiles and Plugins in InitRuntimeFiles
* command: Reload plugins at ReloadCmd too
* command: Don't reload plugins in case of ReloadConfig()
* rtfiles: Split InitRuntimeFiles() into one func for assets and one for plugins
* rtfiles: Remove the unnecessary init function
With this modification the InitRuntimeFiles() and InitPlugins() (if needed)
must be called first, otherwise uninitialized runtime file variables are most
likely.

InfoBar should really receive the resize event, to know the window width
in order to do horizontal scrolling of the command line when it doesn't
fit in the screen. Although currently it doesn't scroll the command line
at all (see issue #2527) and just ignores the resize event, but we
should fix that anyway, so let's forward the resize event to it.

Exposing locking primitives to lua plugins is tricky and may lead to
deadlocks. Instead, if possible, it's better to ensure all the needed
synchonization in micro itself, without leaving this burden to lua code.
Since we've added micro.After() timer API and removed exposing Go timers
directly to lua, now we (probably?) have no cases of lua code possibly
running asynchronously without micro controlling when it is running. So
now we can remove lua.Lock.
This means breaking compatibility, but, until recently lua.Lock wasn't
workable at all (see #2945), which suggests that it has never been
really used by anyone. So it should be safe to remove it.
Since we now expose our own micro.After() API which is more convenient
and safer to use than directly using Go timers, we can remove exposing
Go timers to lua directly.
Directly using Go's time.AfterFunc() from lua is tricky. First, it
requires the lua timer callback to explicitly lock ulua.Lock to prevent
races. Second, it requires the lua timer callback to explicitly redraw
the screen if the callback changes the screen contents (see #2923).
So instead provide micro's own timer API which ensures both
synchronization and redrawing on its own, instead of leaving this burden
to lua code. In fact, its implementation runs the lua timer callback in
the main micro's goroutine (i.e. from micro's perspective it is
synchronous, not asynchronous), so both redrawing and synchronization
are ensured automatically.
Fixes#2923
