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.
Adds new API helper macros `CSTR_AS_OBJ()`, `STATIC_CSTR_AS_OBJ()`, and `STATIC_CSTR_TO_OBJ()`, which cleans up a lot of the current code. These macros will also be used extensively in the upcoming option refactor PRs because then API Objects will be used to get/set options. This PR also modifies pre-existing code to use old API helper macros like `CSTR_TO_OBJ()` to make them cleaner.
Problem: Detecting if the process of a swap file is running fails if the
process is owned by another user.
Solution: Check for the ESRCH error. (closesvim/vim#8436)

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: Macros for MS-Windows are inconsistent, using "32", "3264 and
others.
Solution: Use MSWIN for all MS-Windows builds. Use FEAT_GUI_MSWIN for the
GUI build. (Hirohito Higashi, closesvim/vim#3932)

Problem: Asking about existing swap file unnecessarily.
Solution: When it is safe, delete the swap file. Remove
HAS_SWAP_EXISTS_ACTION, it is always defined. (closesvim/vim#1237)

For historical reasons, uint64_t and friends are defined both as
typedefs and macros. Some platforms that do that define the macros as
identity (#define uint64_t uint64_t), others like NetBSD define to the
backing type (#define uint64_t __uint64_t). This is normally
transparent, except when multiple levels of macro expansions are used
inconsistently.
TODO: Raymond Chen explains[1] racy behavior of the
CreateToolhelp32Snapshot approach. Better approach:
> create a job object and put process P in it. Then call
> QueryInformationJobObject with JobObjectBasicProcessIdList to get the
> list of child processes.
