Problem: formatting long lines is slow
(kawaii-Code)
Solution: optimize gq (internal_format) for long
lines (kawaii-Code)
Implemented two workarounds that significantly reduce
the amount of pointless calls. Ideally the algorithm
would be rewritten not to be n^2, but it's too complicated
with too many corner cases.

Remove `export` pramgas from defs headers as it causes IWYU to believe
that the definitions from the defs headers comes from main header, which
is not what we really want.
Problem: Many places in the code use `findoption()` to access an option using its name, even if the option index is available. This is very slow because it requires looping through the options array over and over.
Solution: Use option index instead of name wherever possible. Also introduce an `OptIndex` enum which contains the index for every option as enum constants, this eliminates the need to pass static option names as strings.
Problem: The entire marktree needs to be traversed each time a sign is
removed from the sentinel line.
Solution: Remove sentinel line and instead keep track of the number of
lines that hold up the 'signcolumn' in "max_count". Adjust this
number for added/removed signs, and set it to 0 when the
maximum number of signs on a line changes. Only when
"max_count" is decremented to 0 due to sign removal do we need
to check the entire buffer.
Also replace "invalid_top" and "invalid_bot" with a map of
invalid ranges, further reducing the number of lines to be
checked.
Also improve tree traversal when counting the number of signs.
Instead of looping over the to be checked range and counting
the overlap for each row, keep track of the overlap in an
array and add this to the count.
FUNC_ATTR_* should only be used in .c files with generated headers.
Defining FUNC_ATTR_* as empty in headers causes misuses of them to be
silently ignored. Instead don't define them by default, and only define
them as empty after a .c file has included its generated header.
We already have an extensive suite of static analysis tools we use,
which causes a fair bit of redundancy as we get duplicate warnings. PVS
is also prone to give false warnings which creates a lot of work to
identify and disable.
Problem: CI: test_termdebug fails
Solution: only test for a changed winlayout, if the window
width actually changed
Also, include an unrelated comment (which doesn't warrant its own patch
number)

long is 32 bits on windows, while it is 64 bits on other architectures.
This makes the type suboptimal for a codebase meant to be
cross-platform. Replace it with more appropriate integer types.

- Move vimoption_T to option.h
- option_defs.h is for option-related types
- option_vars.h corresponds to Vim's option.h
- option_defs.h and option_vars.h don't include each other
Problem: Cannot use an import in 'formatexpr'.
Solution: Set the script context when evaluating 'formatexpr'.

libnvim couldn't be easily used in C++ due to the use of reserved keywords.
Additionally, add explicit casts to *alloc function calls used in inline
functions, as C++ doesn't allow implicit casts from void pointers.
Problem: Code is indented more than necessary.
Solution: Use an early return where it makes sense. (Yegappan Lakshmanan,

Problem: Reading past the end of a line when formatting text.
Solution: Check for not going over the end of the line.

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: The search.c file is a bit big.
Solution: Split off the text object code to a separate file. (Yegappan
