win/spawn: optionally run executable paths with no file extension (#4292)

Add a process options flag to enable the optional behavior. Most users
are likely recommended to set this flag by default, but it was deemed
potentially breaking to set it by default in libuv.

unix,win: utility for setting priority for thread (#4075)

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.

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.)

unix,win: replace QUEUE with struct uv__queue (#4022)

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.

misc: extend getpw to take uid as an argument (#3523)

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.

src: add new metrics APIs (#3749)

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.

sunos: Oracle Developer Studio support (#3374)

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
