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.
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.
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: Giving error messages is not flexible.
Solution: Add semsg(). Change argument from "char_u *" to "char *", also
for msg() and get rid of most MSG macros. (Ozaki Kiichi, closes
vim/vim#3302) Also make emsg() accept a "char *" argument. Get rid of
an enormous number of type casts.

Strings that previously decoded into a msgpack special for representing
BINs with NULs now convert to Blobs. It shouldn't be possible to decode
into this special anymore after this change?
Notably, Lua strings with NULs now convert to Blobs when passed to VimL.
Problem: Obvious mistakes are accepted as valid expressions.
Solution: Be more strict about parsing numbers. (Yasuhiro Matsumoto,
closesvim/vim#3981)

Update vim_str2nr_spec.lua to add more tests that use strict = true.
assert() is compiled out for release builds, but we don't want to
continue running in these impossible situations.
This also resolves the "implicit fallthrough" warnings for the asserts
in switch cases.
UBSAN with clang 10.0 is checking for adding offsets to a `NULL` pointer
which is not allowed. This is not yet checked in the version of clang
used in CI (7.0.0). I will work on cases of this so that tests passes
locally for me.
This could be tested in CI by either upgrading the clang of the
ASAN/UBSAN to 10.0, or add yet another CI target which builds with
clang 10.0.
msgpack-c previously only had MSGPACK_OBJECT_FLOAT, which was a 64-bit
value. Now, 32-bit and 64-bit floats are supported as distinct types,
but we'll simply continue to treat everything as 64-bit types.
