df019cebd5 Revert "provider: delete vimL stderr collector, now that it exists builtin" 
This change exposed a memory issue with buffered channels, possibly
involving GC. Revert until it has been fixed.

This reverts commit 0de019b6a6.

944e3c0619 tui: expose terminal type in 'term' option 
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.

bab2f8200a io: fix handling EOF in vim_fgets 
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.

0f9c90e0ed io: retry fgets on EINTR (#7632) 
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`.

9acd7bfe25 tui: job-control: use saved termios for pty jobs 
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.

b838ad5b7a tui: Disable BCE almost always. #7624 
133ae5eeef implemented BCE (background color erase). But we can't
trust terminfo, so it is safer disable BCE if we are not certain.

Per https://github.com/kovidgoyal/kitty/issues/160#issuecomment-346470545
terminal support for BCE seems to be (1) optional and (2) inconsistent.

9888a54f15 tui: Disable BCE by default. #7624 
133ae5eeef implemented BCE (background color erase).  That's fine if
the system terminfo claims to support it; but our built-in fallback
should not assume it.

Per https://github.com/kovidgoyal/kitty/issues/160#issuecomment-346470545
terminal support for BCE seems to be (1) optional and (2) inconsistent.
So the built-in terminfos should disable it by default.
