It is less error-prone than manually defining header guards. Pretty much
all compilers support it even if it's not part of the C standard.

Problem: Profiling code is spread out.
Solution: Move more profiling code to profiler.c. (Yegappan Lakshmanan,

Problem: Profiling functionality is spread out.
Solution: Put profiling functionality in profiling.c. (Yegappan Lakshmanan,
closes vim/vim#4666)
https://github.com/vim/vim/commit/fa55cfc69d2b14761e2a8bd85bc1e0d82df770aa
Move proftime_T to types.h for now to avoid recursive #include.

- reltimestr(): Produce negative value by comparing the unsigned
proftime_T value to INT64_MAX.
https://github.com/neovim/neovim/issues/10452#issuecomment-511155132
1. The interfaces of nearly all platforms return uint64_t. INT64_MAX is
only half of that.
2. Low-level interfaces like this typically define that there is no
fixed starting point. The only guarantees are that it's (a)
monotonically increasing at a rate that (b) matches real time.

- define proftime_T as signed integer
- profile_sub(): allow negative result

Removes the STARTUPTIME define.

It's a better place to put it. Also slightly documented and reformatted, but
not changed.

Should be better than gettimeofday() since libuv uses higher resolution
clocks on most UNIX platforms. Libuv also tries to use monotonic clocks,
kernel bugs notwithstanding, which is another win over gettimeofday().
Necessary for Windows, which doesn't have gettimeofday(). In vanilla vim,
Windows uses QueryPerformanceCounter, which is the correct primitive for
this sort of things, but that was removed when slimming up the codebase.
Libuv uses QueryPerformanceCounter to implement uv_hrtime() on Windows so
the behaviour of vim profiling on Windows should now be the same.
The behaviour on Linux should be different (better) though, libuv uses more
accurate primitives than gettimeofday().
Other misc. changes:
- Added function attributes where relevant (const, pure, ...)
- Convert functions to receive scalars: Now that proftime_T is always a
(uint64_t) scalar (and not a struct), it's clearer to convert the
functions to receive it as such instead of a pointer to a scalar.
- Extract profiling funcs to profile.c: make everything clearer and reduces
the size of the "catch-all" ex_cmds2.c
- Add profile.{c,h} to clint and -Wconv:
- Don't use sprintf, use snprintf
- Don't use long, use int16_t/int32_t/...
