Problem: Vim can only act as a channel client (ch_open). There is
no way for an external process to initiate a connection
to a running Vim instance using the Channel API.
Solution: Implement ch_listen() and the underlying server-side
socket logic. This allows Vim to listen on a port or
Unix domain socket. When a client connects, a new
channel is automatically created and passed to a
user-defined callback (Yasuhiro Matsumoto).

Just to fix some phrases:
- "A Vim clone". Neovim document says that it is not a clone, but just a
fork https://neovim.io/doc/user/nvim/#nvim
- "Supports a remote GUI". Neovim supports any UI (both GUI and TUI)
that implements its UI protocol, so "a" is not correct
- "Integration with scripting languages". This is true, but it is also
true to Vim (which supports 8 scripting languages AFAIK), so this
probably doesn't need to be said in this document. Instead, what makes
Neovim unique in this "scripting languages" aspect is its first class
support for Lua.

Problem: Vim still supports compiling on NeXTSTEP
Solution: Drop Support (Damien Lejay)
The NeXTSTEP operating system has been obsolete for decades. The
special-case code required to support it adds unnecessary complexity,
preprocessor conditionals, and non-standard workarounds to the codebase.
This commit removes all support for NeXTSTEP, simplifying the code and
build system in several ways:
- Replaced custom configure checks for `union wait` with a standard `AC_CHECK_FUNCS` call for `waitpid`.
- Removed all conditional code that used the non-standard `union wait` for process status, relying solely on a standard `int`.
- Replaced calls to the non-standard `wait4()` function with the POSIX-standard `waitpid()`.
- Cleaned up headers (`os_unix.h`, `os_unixx.h`) to remove NeXT-specific workarounds and macros.
- Removed obsolete NeXT compilation instructions from the INSTALL file.
This change improves maintainability and makes the Unix process handling code more linear and compliant with modern POSIX standards.

Problem: When ch_open() tries to connect to a hostname that resolves to
multiple addresses (e.g., both IPv6 and IPv4), it uses a
single waittime for all connection attempts. If the first IPv6
connection attempt times out, it consumes almost all of the
waittime, leaving insufficient time (often just 1ms) for the
IPv4 attempt to succeed. (reporter)
Solution: Implement a simplified version of Happy Eyeballs (RFC 8305) to
improve connection fallback behavior when IPv6 is unavailable
or slow (thinca).
Distribute the waittime across multiple addresses:
- First address: use up to 250ms (RFC 8305 Connection Attempt Delay) or
half of the total waittime, whichever is smaller
- Middle addresses: divide remaining time equally
- Last address: use all remaining time
This ensures that IPv4 fallback has sufficient time to succeed even when
IPv6 connection attempts fail or timeout.

Problem: With 'autochdir' win_execute() can corrupt the buffer name,
causing :write to use wrong path.
Solution: Save and restore b_fname when 'autochdir' is active
(Ingo Karkat).
This is caused by a bad interaction of the 'autochdir' behavior,
overriding of the current directory via :lchdir, and the temporary
window switching done by win_execute(), manifesting when e.g. a custom
completion inspects other buffers:
1. In the initial state after the :lcd .. we have curbuf->b_fname =
"Xsubdir/file".
2. do_autochdir() is invoked, temporarily undoing the :lcd .., changing
back into the Xsubdir/ subdirectory.
3. win_execute() switches windows, triggering win_enter_ext() →
win_fix_current_dir() → shorten_fnames(TRUE)
4. shorten_fnames() processes *all* buffers
5. shorten_buf_fname() makes the filename relative to the current
(wrong) directory; b_fname becomes "file" instead of "Xsubdir/file"
6. Directory restoration correctly restores working directory via
mch_chdir() (skipping a second do_autochdir() invocation because
apply_acd is FALSE), but b_fname remains corrupted, with the
"Xsubdir/" part missing.
7. expand("%:p") (and commands like :write) continue to use the
corrupted filename, resolving to a wrong path that's missing the
"Xsubdir/" part.
To fix the problem the short filename is saved if its in effect (i.e.
pointed to by curbuf->b_fname) and 'autochdir' happened. It's then
restored in case of a local cwd override. The conditions limit this
workaround to when 'autochdir' is active *and* overridden by a :lchdir.

Problem: Some tests are not valid on OpenBSD.
Solution: Add CheckNotOpenBSD, use it to skip certain tests
(Kevin Goodsell).
Test_readdirex_sort performs locale-dependent sorting. OpenBSD has
minimal locale support.
Test_stdin_no_newline hangs on OpenBSD and FreeBSD. I don't know exactly
why, but it may be due to bash not exiting at the end of the test. This
is skipped in the FreeBSD CI runs because bash is not installed.
Test_detect_fifo uses /dev/fd/ files (via process substitution) as
FIFOs. On OpenBSD the files in /dev/fd are not FIFOs.
