Problem: The legacy signlist data structures and associated functions are
redundant since the introduction of extmark signs.
Solution: Store signs defined through the legacy commands in a hashmap, placed
signs in the extmark tree. Replace signlist associated functions.
Usage of the legacy sign commands should yield no change in behavior with the
exception of:
- "orphaned signs" are now always removed when the line it is placed on is
deleted. This used to depend on the value of 'signcolumn'.
- It is no longer possible to place multiple signs with the same identifier
in a single group on multiple lines. This will now move the sign instead.
Moreover, both signs placed through the legacy sign commands and through
|nvim_buf_set_extmark()|:
- Will show up in both |sign-place| and |nvim_buf_get_extmarks()|.
- Are displayed by increasing sign identifier, left to right.
Extmark signs used to be ordered decreasingly as opposed to legacy signs.
Problem: buffer text with composing chars are converted from UTF-8
to an array of up to seven UTF-32 values and then converted back
to UTF-8 strings.
Solution: Convert buffer text directly to UTF-8 based schar_T values.
The limit of the text size is now in schar_T bytes, which is currently
31+1 but easily could be raised as it no longer multiplies the size
of the entire screen grid when not used, the full size is only required
for temporary scratch buffers.
Also does some general cleanup to win_line text handling, which was
unnecessarily complicated due to multibyte rendering being an "opt-in"
feature long ago. Nowadays, a char is just a char, regardless if it consists
of one ASCII byte or multiple bytes.
Problem: [security]: Use-after-free in win_close()
Solution: Check window is valid, before accessing it
If the current window structure is no longer valid (because a previous
autocommand has already freed this window), fail and return before
attempting to set win->w_closing variable.

Problem: buffer-overflow in trunc_string()
Solution: Add NULL at end of buffer
Currently trunc_string() assumes that when the string is too long,
buf[e-1] will always be writeable. But that assumption may not always be
true. The condition currently looks like this
else if (e + 3 < buflen)
[...]
else
{
// can't fit in the "...", just truncate it
buf[e - 1] = NUL;
}
but this means, we may run into the last else clause with e still being
larger than buflen. So a buffer overflow occurs.
So instead of using `buf[e - 1]`, let's just always
truncate at `buf[buflen - 1]` which should always be writable.

Problem: crash with bt_quickfix1_poc when cleaning up

While at it, increase the crash timeout slightly, so that CI has a
chance to finish processing the test_crash() test.

Problem: [security]: overflow in ex address parsing
Solution: Verify that lnum is positive, before substracting from

[security]: overflow in ex address parsing
When parsing relative ex addresses one may unintentionally cause an
overflow (because LONG_MAX - lnum will overflow for negative addresses).
So verify that lnum is actually positive before doing the overflow
check.

Problem: [security]: overflow with count for :s command
Solution: Abort the :s command if the count is too large
If the count after the :s command is larger than what fits into a
(signed) long variable, abort with e_value_too_large.
Adds a test with INT_MAX as count and verify it correctly fails.
It seems the return value on Windows using mingw compiler wraps around,
so the initial test using :s/./b/9999999999999999999999999990 doesn't
fail there, since the count is wrapping around several times and finally
is no longer larger than 2147483647. So let's just use 2147483647 in the
test, which hopefully will always cause a failure

Problem: wast filetype should be replaced by wat filetype
Solution: start using the official wat filetype name
runtime: rename `wast` filetype to `wat` (Wasm text format)
The problem is the name of the current filetype wast. When the plugin
was initially created, the file extension for Wasm text format was not
fixed and .wast was more popular.
However, recently .wat became the official file extension for
WebAssembly text (WAT) format and .wast is now a file extension for the
unofficial WAST format, which is a superset of .wat for the convenience
to describe the Wasm specification conformance tests.
https://webassembly.js.org/docs/contrib-wat-vs-wast.html
However for now, let's keep using the `wat` filetype even for the .wast
extension, so that we at least do not lose the filetype settings and
syntax highlighting. This can be adjusted later, if it turns out to have
a separate need for.

The 'termsync' option enables a mode (provided the underlying terminal
supports it) where all screen updates during a redraw cycle are buffered
and drawn together when the redraw is complete. This eliminates tearing
or flickering in cases where Nvim redraws slower than the terminal
redraws the screen.
Problem:
'nofsync' may lose data if the system has a hard shutdown. #9888
Solution:
Change default to 'fsync'. This may be revisited in the future when
'nofsync' can be made safer.
libtermkey does not interpret OSC sequences that end with a BEL (0x07)
instead of an ST (0x1b 0x5c) terminator. This causes these tests to fail
since the OSC response is now parsed via libtermkey. Change the tests to
use the ST terminator to appease libtermkey.
