Solution: Use ht_changed in a few more places.

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: Cannot use a lambda for 'completefunc' and 'omnifunc'.
Solution: Implement lambda support. (Yegappan Lakshmanan, closesvim/vim#9257)

Enable and fix bugprone-misplaced-widening-cast warning.
Fix some modernize-macro-to-enum and readability-else-after-return
warnings, but don't enable them. While the warnings can be useful, they
are in general too noisy to enable.
Problem: Confusing error message with white space before comma in the
arguments of a function declaration.
Solution: Give a specific error message. (closesvim/vim#2235)

BREAKING CHANGE: When using a Funcref converted from a Lua function as
a method in Vim script, the result of the base expression is now passed
as the first argument instead of being ignored.

Omit fe_check_type: always NULL in legacy Vim script.
Problem: ERROR_UNKNOWN clashes on some systems.
Solution: Rename ERROR_ to FCERR_. (Ola Söder, closesvim/vim#5415)

Remove ERROR_BOTH which was removed from Vim in patch 7.4.1582.
"cfuncs" was only ever used to wrap luarefs. As vim8script is
finished and will not be developed further, support for "cfuncs"
for other usecases are not planned. This abstraction was immediately
broken anyway in order to get luarefs out of userfuncs again.
Even if a new kind of userfunc needs to be invented in the future,
likely just extending the FC_... flag union directy, instead of
invoking unnecessary heap object and c function pointer indirection,
will be a more straightforward design pattern.
Problem: Insufficient testing for exception handling and the "attention"
prompt.
Solution: Add test cases. (Yegappan Lakshmanan, closesvim/vim#5681)

Fix memory leak from last char_u refactor.
`!did_throw` doesn't exactly imply `!current_exception`, as `did_throw = false`
is sometimes used to defer exception handling for later (without forgetting the
exception). E.g: uncaught exception handling in `do_cmdline()` may be deferred
to a different call (e.g: when `try_level > 0`).
In #7881, `current_exception = NULL` in `do_cmdline()` is used as an analogue of
`did_throw = false`, but also causes the pending exception to be lost, which
also leaks as `discard_exception()` wasn't used.
It may be possible to fix this by saving/restoring `current_exception`, but
handling all of `did_throw`'s edge cases seems messier. Maybe not worth
diverging over.
This fix also uncovers a `man_spec.lua` bug on Windows: exceptions are thrown
due to Windows missing `man`, but they're lost; skip these tests if `man` isn't
executable.
