Notes regarding the removal of specific items:
- Aztec C: only on the Amiga.
- mch_check_win(): doesn't exist anymore.
- Comment in ex_cmds.c: It seems the context for this comment was
removed, but the comment was inadvertantly left alone.
A similar macro is defined in the Linux kernel [1].
To refactor the code I used a slightly modified Coccinelle script I found in
[2].

Problem : Unchecked return value (CHECKED_RETURN) @ 8554.
Diagnostic : Real issue.
Rationale : Other invocations of `do_source` are checked and generate
an error message if fail. There seems to be no reason why
this particular instance could not fail the same.
Resolution : Check invocation and generate error message on failure.
Nvim now relies much less on setting terminal mode to cooked mode, remove most
calls to settmode, except for those that happen on startup or when suspending.
Eventually even those will be handled by the UI layer.
Problem : Double free @ 5213.
Diagnostic : False positive.
Rationale : Suggested error path contains two consecutive invocations
of `ends_excmd(*p)` having different results, which is not
possible. First invocation is before the while loop. Second
invocation is the while loop condition itsef.
Resolution : Refactor while loop into do-while loop. That removes the
impossible path from analysis, and, in addition, is a bit
more efficient.
Problem : Uninitialized argument value @ 7704.
Diagnostic : False positive.
Rationale : Error occurs if `switch(spec_idx)` doesn't enter any case,
which should not occur after
`spec_idx = find_cmdline_var(...)` returned non-negative.
Resolution : Add default clause to switch and error if reached.
This uses the provider/scripting infrastructure to reintroduce python support
through the msgpack-rpc API.
A new 'initpython' option was added, and it must be set to a command that will
bootstrap the python provider the first time it's needed.
- The 'stripdecls.py' script replaces declarations in all headers by includes to
generated headers.
`ag '#\s*if(?!ndef NEOVIM_).*((?!#\s*endif).*\n)*#ifdef INCLUDE_GENERATED'`
was used for this.
- Add and integrate gendeclarations.lua into the build system to generate the
required includes.
- Add -Wno-unused-function
- Made a bunch of old-style definitions ANSI
This adds a requirement: all type and structure definitions must be present
before INCLUDE_GENERATED_DECLARATIONS-protected include.
Warning: mch_expandpath (path.h.generated.h) was moved manually. So far it is
the only exception.
