While the new RPC encoder/decoder implementation in general should have
less overhead than the deleted UIBridge serializer previously used for
the TUI, it regresses on redraw latency in one important aspect.
The old bridge implementation allowed the TUI to process a
previous screen line internally in parallel with the main thread
rendering the next one in win_line etc. As printing the escape
sequences in highlighted cells has a considerable hit in profiles,
this has a substantial effect on redraw latency. The RPC implementation,
however, waits with sending any data until either a flush, or the buffer is full.
This change lowers the granularity of communication again, using an
adjustable threshold counted in number of cell events (discounting
long repeats and clearing as maximum a single extra event).
The current value is guesstimated to something simple on a reasonable
scale, which should be bigger than a single line, but multiple events
for a big multi-window screen.

Problem:
1. Some calls to preserve_exit() don't put a message in IObuff, so the
IObuff printed by preserve_exit() contains unrelated information.
2. If a TUI client runs out of memory or receives a deadly signal, the
error message is shown on alternate screen and cannot be easily seen
because the TUI exits alternate screen soon afterwards.
Solution:
Pass error message to preserve_exit() and exit alternate screen before
printing it.
Note that this doesn't fix the problem that server error messages cannot
be easily seen on exit. This is tracked in #21608 and #21843.
Problem: Cursor may move with autocmd in Visual mode.
Solution: Restore "VIsual_active" before calling check_cursor().

Any logic involving CMAKE_BUILD_TYPE is automatically broken as it won't
work with multi-config generators. The only exception is if we
explicitly check whether the current generator is single-config as well.
Instead, use generator expressions or cmake variables that allows to set
options for certain build types only such as
INTERPROCEDURAL_OPTIMIZATION_<CONFIG>.
Opt to generate all headers with optimization level O2 with no debug
information for all build types as that is the simplest way to make it
behave the same for all generators.
The "length-of-one" trick, where the last element of a struct is an
array of size 1, but extra size is allocated when calling malloc where
it uses more than 1 element in the array, cause problems with some
compilers. Some compilers set _FORTIFY_SOURCE=2 by default which
incorrectly considers it as an overflow. More information:
https://github.com/neovim/neovim/issues/223#issuecomment-1413828554
Using flexible array members allows us to to properly convey to the
compiler that its size may be larger than 1. This also enables us to
remove lengthy workarounds that are unreliable, as they depend on
CMAKE_BUILD_TYPE which isn't defined for multi-config generators.

Problem:
When a TUI client is suspended it still receives UI events from the
server, and has to process these accumulated events when it is resumed.
With mulitple TUI clients this is a bigger problem, considering the
following steps:
1. A TUI client is attached.
2. CTRL-Z is pressed and the first client is suspended.
3. Another TUI client is attached.
4. CTRL-Z is pressed and a "suspend" event is sent to both clients. The
second client is suspended, while the first client isn't able to
process the event because it has already been suspended.
5. The first client is resumed. It processes the accumulated "suspend"
event and suspends immediately.
Solution:
Make a TUI client detach on suspend and re-attach on resume.
Problem: The 'statuscolumn' width is being estimated without the
proper context. In particular, this resulted in the fact
that a custom fold column could be included in the estimated
`number_width()`, and doubly added when actually drawing the
statuscolumn due to `win_col_off()` also adding the
`'foldcolumn'` width. Resulting in a status column that is
`'foldcolumn'` cells wider than necessary.
Solution: Estimate 'statuscolumn' width in `get_statuscol_str()` when
a buffer's line count has changed.
Problem: "1v" may select block with wrong size. (Evgeni Chasnovski)

This value can not be relied on as it doesn't work for
multi-configuration generators. I don't think this undocumented option
is used much, if at all, so I think we should remove it.
Currently, only the nvim target uses ccache but not libnvim or
unittests. It is generally a good idea to operate on targets rather than
globally, but this is an exception as there isn't a target where we
don't want to use ccache on.

Initial benchmarks show that this gives a nice 50% compile time
reduction for neovim. This shouldn't affect users or CI, but it's a nice
speedup for local development. The C_COMPILER_LAUNCHER target property
is only supported by Makefiles and Ninja generators only, so this won't
give a speedup when using the Xcode and Visual Studio generators even if
ccache is available.
Problem: Code is indented more than necessary.
Solution: Use an early return where it makes sense. (Yegappan Lakshmanan,
