Calling `uv_timer_start(h, cb, 0, 0)` from a timer callback resulted in
the timer running immediately because it was inserted at the front of
the timer heap.
If the callback did that every time, libuv would effectively busy-loop
in `uv__run_timers()` and never make forward progress.
Work around that by collecting all expired timers into a queue and only
running their callback afterwards.

Add uv_thread_setpriority for setting priority for threads created by
uv_thread_create. Add uv_thread_getpriority for getting thread priority.
For Linux by default, if the scheduling policy is SCHED_OTHER and the
priority is 0, we need to set the nice value.

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.)
Recent versions of gcc have started emitting warnings about the liberal
type casting inside the QUEUE macros. Although the warnings are false
positives, let's use them as the impetus to switch to a type-safer and
arguably cleaner approach.

`FreeBSD` defines `ENODATA` in /usr/include/c++/v1/errno.h which is only visible
if C++ is the compilation unit. This can cause interop issues when
integrating libuv build with C on a C++ project. Avoid this issue by
directly defining with the value defined in the file previously
mentioned.
This commit adds the ability to dump core when sending the `SIGQUIT`
signal on Windows. The change reads in the current registry setting for
local dumps, and attempts to write out to that location before killing
the process. See [collecting-user-mode-dumps] for registry and pathing
details. This behavior mimics that of the dumps created by the typical
Windows Error Reporting mechanism.

This code would previously get confused between rounds of the barrier
being called and a thread might incorrectly get stuck (deadlock) if the
next round started before that thread had exited the current round.
Avoid that by not starting the next round in++ before out-- has reached
zero indicating that all threads have left the prior round.
And fix it that on Windows by replacing the implementation with the one
from unix. There are some awkward platform-specific redirection here
with an extra malloc that is not needed on Win32, but that will be fixed
in libuv v2.

File system operations may return uid and gid values, which we may want
to pretty-print. We already have the code for getting information for
the current user, so just need to add a parameter to make it exposed for
every user. We expose information about groups in a similar manner also.
Calling uv_fs_fstat for file types other then disk type was resulting in
error on Windows while it was retrieving data on Linux. This change
enables getting fstat for pipes and character files on Windows with data
fetched being as reasonable as possible.
A simple test is also added to check this behavior on all platforms. It
uses stdin, stdout and stderr. uv_fs_fstat needs to pass with disk files
pipes and character files (eg. console).

The following metrics are now always recorded and available via the new
uv_metrics_info() API.
* loop_count: Number of event loop iterations.
* events: Total number of events processed by the event handler.
* events_waiting: Total number of events waiting in the event queue when
the event provider request was made.
Benchmarking has shown no noticeable impact recording these metrics.

Make unices and windows consistent when closing a pipe while it's
connecting so they all return `UV_ECANCELED`.
Avoid race condition between `pipe_connect_thread_proc()` and `uv_close()` when
accessing `handle->name`.

Backported thread affinity feature and related dependency commits
from master. It will add support for those APIs: uv_cpumask_size,
uv_thread_setaffinity, uv_thread_getaffinity.
The supported platforms are Linux, Freebsd, and Windows.
Empty implementations (returning UV_ENOTSUP) on non-supported platforms
(such as OS X and AIX).
If `uv_close` was called while a connect was pending, we would fail to
release the resources for the connection, since we had not yet set the
type of the struct.
Fix a thread data-race on slow connect path code: only permitted to
write to `req` on threads, as anything else causes data race
corruption.
There seemed be a small variety of other resource management bugs in
edge cases, which turned out to make this a lot larger than initially
expected.

Replacement for the usage pattern where people use uv_cpu_info() as an
imperfect heuristic for determining the amount of parallelism that is
available to their programs.
Fixes#3493.
Added in https://github.com/libuv/libuv/pull/742, these values are
typically defined as unsigned (since Linux 2.4). Only -1 is special,
representing an invalid id (e.g. see setreuid).

Oracle Developer Studio requires public functions to be
defined as "__global" when "-fvisibility=hidden" used as
added by [#3005](https://github.com/libuv/libuv/pull/3005).
For documentation on `__global` see Reducing Symbol Scope in
Oracle Developer Studio C/C++ guide
https://www.oracle.com/solaris/technologies/symbol-scope.html.
fs_utime_round test failed as timespec.tv_nsec conversion to
double resulted in negative number. Skip this test for
__SPRO_C builds.
Note that it was necessary to have C99 language features
enabled with Studio compiler (-xc99=all) as version v1.41.0
has other commits that have used C99 features.
Tested with:
- cc: Studio 12.6 Sun C 5.15 SunOS_sparc 152881-05 2019/10/30
- gcc (GCC) 11.2.0
