ref #7649
ref #766427f9b1c7b0 caused a regression: it uses loop_schedule_deferred() to
defer emitting the "enable focus reporting" termcode. tui_main() never
processes `tui_loop.events` (which loop_schedule_deferred() depends on),
so the event was never actually processed.
But fixing that (by processing `tui_loop.events`) would bring back the
problem 27f9b1c7b0 tried to fix: it still emits the event too soon.
Instead, do a little dance: schedule the event on `main_loop` and then
forward it to `tui_loop`.
NOTE: after this commit, in tmux 2.3 with `focus-events` enabled,
FocusGained is fired on startup and when resuming from suspend.
Using `script` to record the terminal session (and `vterm-dump` to
post-process the result):

Note: there are three changes to ascii_isident. Reverting first two (in
find_special_key and first in get_special_key_code) normally fails the new test
with empty &isident, but reverting the third does not. Hence adding `>` to
&isident.

Since "builtin" terminfo definitions were implemented (7cbf52db1b),
the decisions made by tui.c and terminfo.c are more relevant. Exposing
that decision in the 'term' option helps with troubleshooting.
Also: remove code that allowed setting t_Co. `:set t_Co=…` has never
worked; the highlight_spec test asserting that nvim_set_option('t_Co')
_does_ work makes no sense, and should not have worked.
If an EOF is returned from `fgets`, `vim_fgets` might spin forever, as
it tries to consume the current line.
A `NULL` return value from `fgets` should break out of the function
(unless `errno` is `EINTR`), and then `feof` should be used to check for
the EOF condition on the stream.
The calls to `fgets` in `src/nvim/if_cscope.c` (and elsewhere) can show
communication errors to the user if a signal is delivered during its
system calls. For plugins that proxy subprocess output into cscope
requests, a `SIGCHLD` might *always* interfere with calls into `fgets`.
To see this in a debugger, put a breakpoint on `cs_reading_emsg` and
watch signals come in (with lldb, using `process handle --notify true
--pass true`). Next, run a subcommand from neovim that calls through
cscope when it returns. A tag picker plugin, like vim-picker and fzy,
with `cscopetag` and `cscopetagorder=0` set, reproduced this reliably.
The breakpoint will hit after a `SIGCHLD` is delivered, and `errno` will
be set to 4, `EINTR`.
The caller of `fgets` should retry when `NULL` is returned with `errno`
set to `EINTR`.
On startup, if running in a terminal, save the termios properties.
Use the saved termios for `:terminal` and `jobstart()` pty jobs.
This won't affect nvim spawned outside of a terminal.
questions:
- This affects `:terminal` and `jobstart({'pty'✌️true})`.
Should we be more conservative for `jobstart({'pty'✌️true})` (e.g.
pass NULL to forkpty() and let the OS defaults prevail)?
- Note: `iutf8` would not be set in that case.
