misc: export WTF8 conversion utilities (#4021)

As promised in #2970, this attempts to migrate code to a common set of
utilities in a common place in the code and use them everywhere. This
also exports the functionality, since the Windows API with
WideCharToMultiByte is fairly verbose relative to what libuv and
libuv's clients typically need, so it is useful not to require clients
to reimplement this conversion logic unnecessarily (and because Windows
is not 64-bit ready here, but this implementation is.)

Document that we return UINT64_MAX if the cgroup limit is set to the

returns 9223372036854771712 when no limit is set (which according to

PAGE_SIZE). So make sure we also detect this case for cgroupv1.

unix: error when uv_setup_args() is not called

This commit updates uv_{get,set}_process_title() to return an
error when uv_setup_args() is needed, but has not been called.

Per-platform behavior after this commit:

- Windows: uv_setup_args() does nothing, get/set process title
works as before.
- Unix: get/set process title will return ENOBUFS if
uv_setup_args() wasn't called, if it failed, or if the process
title memory has been freed by uv__process_title_cleanup()
(via uv_library_shutdown()).
- AIX: set process title returns ENOBUFS if uv_setup_args()
wasn't called, if it failed to allocate memory for the argv
copy, or if the proctitle memory has been freed by
uv__process_title_cleanup() (via uv_library_shutdown).
Getting the process title will do the same except it can
still succeed if uv_setup_args() was called but failed to
allocate memory for the argv copy.
- BSD: uv_setup_args() is only needed for getting the initial
process title; if uv_setup_args() is not called then any
get_process_title calls() before a set_process_title() call
will return an empty string.
- Platforms that use no-proctitle.c: get will return an empty
string, set is a no-op (these are the same as before this commit)

unix,win: add uv_library_shutdown()

Make it possible to explicitly tell libuv to release any resources
it's still holding onto (memory, threads, file descriptors, etc.)

Before this commit, cleanup was performed in various destructors.
This commit centralizes the cleanup logic, enabling the addition of
`uv_library_shutdown()`, but maintains the current observable behavior
of cleaning up when libuv is unloaded by means of `dlclose(3)`.

linux: make cpu_times consistently be milliseconds

On Linux, cpu_times have been calculated differently to all other
platforms for a while. Other platforms (FreeBSD, Mac, Windows) are all
in milliseconds, but Linux has been returning values ten times larger.

libuv has not previously documented what unit cpu_times uses, even
though NodeJS did - as milliseconds.

Here we're both documenting that the cpu_times are indeed in
milliseconds, and fixing the inconsistency on Linux.
