Instead of nested linked lists, store autocommands in a flat, contiguous
kvec_t, with one kvec_t per event type. Previously patterns were stored
in each node of the outer linked list, so they can be matched only once
on repeating patterns. They are now reference counted and referenced in
each autocommand, and matching is skipped if the pattern repeats. Speeds
up creation and deletion, execution is not affected.

fix(extmarks): disallow removing extmarks in on_lines callbacks
decor_redraw_start (which runs before decor_providers_invoke_lines) gets
references for the extmarks on a specific line. If these extmarks are
deleted in on_lines callbacks then this results in a heap-use-after-free
error.

Here's the headline: when run in sync mode (last argument cb=NULL),
these functions don't actually use the uv_loop_t.
An earlier version of this patch instead replaced fs_loop with
using main_loop.uv on the main thread and luv_loop() on luv worker
threads. However this made the code more complicated for no reason.
Also arbitrarily, half of these functions would attempt to handle
UV_ENOMEM by try_to_free_memory(). This would mostly happen
on windows because it needs to allocate a converted WCHAR buffer.
This should be a quite rare situation. Your system is pretty
much hosed already if you cannot allocate like 50 WCHAR:s.
Therefore, take the liberty of simply removing this fallback.
In addition, we tried to "recover" from ENOMEM in read()/readv()
this way which doesn't make any sense. The read buffer(s) are already
allocated at this point.
This would also be an issue when using these functions on a worker
thread, as try_to_free_memory() is not thread-safe. Currently
os_file_is_readable() and os_is_dir() is used by worker threads
(as part of nvim__get_runtime(), to implement require from 'rtp' in
threads).
In the end, these changes makes _all_ os/fs.c functions thread-safe,
and we thus don't need to document and maintain a thread-safe subset.
Problem: Functions for string manipulation are spread out.
Solution: Move string related functions to a new source file. (Yegappan

Problem: The 'statusline'-format ui elements do not receive right
click events when "mousemodel" is "popup*"
Solution: Do not draw popupmenu and handle click event instead.
Previously, there were three low-level delay entry points
- os_delay(ms, ignoreinput=true): sleep for ms, only break on got_int
- os_delay(ms, ignoreinput=false): sleep for ms, break on any key input
os_microdelay(us, false): equivalent, but in μs (not directly called)
- os_microdelay(us, true): sleep for μs, never break.
The implementation of the latter two both used uv_cond_timedwait()
This could have been for two reasons:
1. allow another thread to "interrupt" the wait
2. uv_cond_timedwait() has higher resolution than uv_sleep()
However we (1) never used the first, even when TUI was a thread, and
(2) nowhere in the codebase are we using μs resolution, it is always a ms
multiplied with 1000.
In addition, os_delay(ms, false) would completely block the thread for
100ms intervals and in between check for input. This is not how event handling
is done alound here.
Therefore:
Replace the implementation of os_delay(ms, false) to use
LOOP_PROCESS_EVENTS_UNTIL which does a proper epoll wait with a timeout,
instead of the 100ms timer panic.
Replace os_microdelay(us, false) with a direct wrapper of uv_sleep.
Problem: 'statuscolumn' width may be reset after it has been drawn
when multiple windows contain the same buffer. This results
in an offset for the drawn cursor position.
Solution: Loop over all windows (twice) prior to drawing them to
reset the 'statuscolumn' width and validate the sign
column when necessary.
Problem: Small source file problems; outdated list of distributed files.
Solution: Small updates to source files and list of distributed files.

The shipped versions of xdiff already does everything diff does, so this
duplication of tools isn't necessary. Furthermore, this setup is more
consistent overall, as the 'diffopt=external' option should be for
external programs rather than programs we bundle neovim with.
Install diffutils for oldtests in CI to avoid needing to modify tests.

This will add all interface include directories property from all
targets to main_lib. This may not be universally wanted, in which case
we can revisit/rework it.

- There is no "resource leak".
- "return 0" is definitely not the correct behavior if we ever occur a
platform where this would fail.
- There was no problem here to fix. so let's not "fix" it.
- once CI is upgraded to gcc 13, we'll figure out the correct way to make
it shut the fuck up. warnings on non-ci platforms are not critical.
This one generates a runtime/ file instead of a source file.
But otherwise it works the same like all other generators.
It has the same prerequisites (shared and mpack modules, etc), and,
importantly, it uses results from the source generators.
The odd location makes it easy to overlook when refactoring generators
(like I did last time, lol)
