Allow Include What You Use to remove unnecessary includes and only
include what is necessary. This helps with reducing compilation times
and makes it easier to visualise which dependencies are actually
required.
Work on https://github.com/neovim/neovim/issues/549, but doesn't close
it since this only works fully for .c files and not headers.
Problem: Lambda for option that is a function may be garbage collected.
Solution: Set a reference in the funcref. (Yegappan Lakshmanan,

Enable and fix bugprone-misplaced-widening-cast warning.
Fix some modernize-macro-to-enum and readability-else-after-return

are in general too noisy to enable.

If the call to `qf_setup_state()` in `qf_init_ext()` fails, control flow jumps
to label `qf_init_end` where a call to `qf_update_buffer()` is made with
`old_last` as a function call argument.
Prior to this patch, `old_last` would not yet have been initialized to its
default value of `NULL`, resulting in `qf_update_buffer()` attempting to compare
against its uninitialized value (quickfix.c:3882) then later forwarding it to
`qf_fill_buffer()` where the address is dereferenced and repeatedly read from/
written to for performing core qflist operations.
Depending on what the default value of `old_last` was, the results may range
from a best case scenario of neovim terminating with SIGSEGV from an attempt to
dereference an invalid pointer (quickfix.c:4056) to memory corruption if it
contained some other value that results in `qfp` being initialized from
`old_last->qf_next` (after which it is subsequently written to and read from in
a fairly arbitrary fashion).
Though extremely unlikely, it's possible for there to be security considerations
as a user can ensure that the next call to `qf_setup_state()` fails.
This patch ensures that `old_last` is NULL-assigned before control flow jumps to
`qf_init_end`.
Closes#20639.

Solution: Do not allow for recursion.

Cherry-pick Test_qflist_statusmsg() from patch 8.2.4617.
This was used in the past with assumption that curwin/curbuf
is "special" but this has not been true since basically forever
at this point.
Reduce NOT_VALID/CLEAR panic in options.lua . These should not
be set if an effect of the option is causing something
which by itself invokes redraw_later().
Problem: confusing error when using :cc without error list. (Gary Johnson)
Solution: Give the "no errors" error.

Cherry-pick e_quickfix -> e_no_errors rename from patch 8.2.3190.

Morris)
Solution: Add type casts.

Still keep it size_t, but avoid calculating multiple times.
Problem: Vim9: 'cpo' can become empty.
Solution: Use empty_option instead of an empty string. Update quickfix
buffer after restoring 'cpo'. (closesvim/vim#7608)

Omit test as it is Vim9 script.
Problem: The option.c file is too big.
Solution: Split off the code dealing with strings. (Yegappan Lakshmanan,

Cherry-pick set_string_option_direct_in_win() from patch 8.1.1405.
Cherry-pick shift_line() comment change from patch 8.1.2096.
Move 'clipboard' default parsing to didset_string_options().
Reorder option flags to put Nvim-only flags at the end.

Omit duplicate docs. It's removed in patch 8.2.3623.
Nvim doesn't seem to need callback_set() as it was omitted when patch 8.1.1437
was first ported.
Problem: Some code in options.c fits better elsewhere.
Solution: Move functions from options.c to other files. (Yegappan

Problem: The screen.c file is much too big.
Solution: Split it in three parts. (Yegappan Lakshmanan, closesvim/vim#4943)
7528d1f6b5
This is an approximation vim-patch 8.1.2057. Applying the patch directly
isn't feasible since our version of screen.c has diverged too much,
however we still introduce drawscreen.c and drawline.c:
- screen.c is now a much smaller file used for low level screen functions
- drawline.c contains everything needed for win_line()
- drawscreen.c contains everything needed for update_screen()
