When the end character in a range matches a different standard range
(e.g., [0-z]), the range would be incorrectly detected as the class of
the end character (CLASS_az).
Instead of using a fallthrough, immediately FAIL when the end character
doesn't match the expected range.
The terminfo entry for linux only advertises 8 colours, but nvim tries
to make it display 16 colours anyway, resulting in erroneous SGR control
sequences for colours 8 and above. The Linux kernel terminal emulator
itself has actually understood the 256-colour control sequences since
version 4.8 and the 16-colour control sequences since version 4.9. Thus
we apply the same terminfo fixup as we apply for *xterm* and *256*, to
emit the 16-colour and 256-colour control sequences even if terminfo's
setaf and setab do not advertise them.
As part of the refactoring in #5119, some vim_strchr() were changed to
strchr(). However, vim_strchr() behaves differently than strchr() when
c is NUL, returning NULL instead of a pointer to the NUL.
Revert the strchr() calls where it isn't known whether c is NUL, since
this causes a semantic change the surrounding code doesn't expect. In
the case of #6650, this led to a heap overrun.
Closes#6650

Asynchronous API functions are served immediately, which means pending
input could change the state of Nvim shortly after an async API function
result is returned.
nvim_get_mode() is different:
- If RPCs are known to be blocked, it responds immediately (without
flushing the input/event queue)
- else it is handled just-in-time before waiting for input, after
pending input was processed. This makes the result more reliable
(but not perfect).
Internally this is handled as a special case, but _semantically_ nothing
has changed: API users never know when input flushes, so this internal
special-case doesn't violate that. As far as API users are concerned,
nvim_get_mode() is just another asynchronous API function.
In all cases nvim_get_mode() never blocks for more than the time it
takes to flush the input/event queue (~µs).
Note: This doesn't address #6166; nvim_get_mode() will provoke #6166 if
e.g. `d` is operator-pending.
Closes#6159
