systemclock: Use clock_nanosleep for higher accuracy

The various wait implementation have a latency ranging from 50 to 500+
microseconds. While this is not a major issue when dealing with a low number of
waits per second (for ex: video), it does introduce a non-negligeable jitter for
synchronization of higher packet rate systems.

The `clock_nanosleep` syscall does offer a lower-latency waiting system but is
unfortunately blocking, so we don't want to use it in all scenarios nor for too
long.

This patch makes GstSystemClock use clock_nanosleep (if available) as such:
* Any wait below 500us uses it
* Any wait below 2ms will first use the regular waiting system and then
  clock_nanosleep

taskpool: expose new "shared" task pool implementation

While the default implementation will spawn a thread per new
pushed task, this new implementation instead spawns a maximum
number of threads, then queues new tasks on existing threads.

The thread that the new task will be queued on is picked in
a pretty naive fashion, by simply popping the first thread
from a queue and pushing it back to the tail, but this is
an implementation detail and can always be sophisticated
in the future if the need arises.

gstinfo: colorize PIDs in log messages

The PIDs on log lines were supposed to be colorized before, but the
escape sequence was incorrect.  With this change, the code uses the
correct sequence to colorize those PIDs.  E.g., instead of `\033[334m`
(incorrect), use `\033[34m` (correct).

This makes the log messages easier to read.  It also reduces the chance
that a buggy terminal will choke on the invalid escape sequence.

gstvalue: expose gst_value_deserialize_with_pspec()

Typing hints can only be passed to gst_value_deserialize()

can only target the desired type for the top-level elements,
making it for example impossible to deserialize an array of
flags to the expected type.

This commit exposes a new function, gst_value_deserialize_full(),
that takes an optional pspec as the extra parameter, and updates
the deserialization code to pass around that pspec, or the
element_spec when recursively parsing the elements of a list-type

fix clang 10 warnings

the typesystem checks in g_atomic_pointer_compare_and_exchange
seem to trigger some false positives with clang 10

Part-of: <https://gitlab.freedesktop.org/gstreamer/gstreamer/-/merge_requests/584>

aggregator: fix iteration direction in skip_buffers

Subclasses use the pad segment to determine whether a buffer
should be skipped, we thus don't want to check if a buffer
needs to be skipped before processing the segment it's part
of.

gsturi: Add new API for storing unmodified userinfo / fragment

New API: gst_uri_from_string_escaped()

Identical to gst_uri_from_string() except that the userinfo and
fragment components of the URI will not be unescaped while parsing.

This is needed for correctly parsing usernames or passwords with `:`
in them such as reported at:
https://gitlab.freedesktop.org/gstreamer/gst-plugins-bad/-/issues/831

Part-of: <https://gitlab.freedesktop.org/gstreamer/gstreamer/-/merge_requests/583>

tests: Add more tests for gsturi

Add tests that exercise unescaping of userinfo and fragments.

Also convert to a modular macro-based definition so that we can reuse
the list of tests in the next commit.

aggregator: expose sample selection API

See https://gitlab.freedesktop.org/gstreamer/gst-plugins-base/-/issues/771
for context.

This exposes new API that subclasses must call from their
aggregate() implementation to signal that they have selected
the next samples they will aggregate: gst_aggregator_selected_samples()

GstAggregator will emit a new signal there, `samples-selected`,
handlers can then look up samples per pad with the newly-added
gst_aggregator_peek_next_sample.

In addition, a new FIXME is logged when subclasses haven't actually
called `selected_samples` from their aggregate() implementation.

tracer: declare GstTracer API stable

It's been around for more than 4 years and people have built
lots of stuff on top of it, doesn't really make sense to keep
it marked as unstable. We're unlikely to change it now, and
we can always deprecate it and make a new one if needed.

This stabilises the following API:
- gst_tracer_register()
- gst_tracing_get_active_tracers()
- gst_tracing_register_hook()
- gst_tracer_record_new()
- gst_tracer_record_log()

Might also help a bit with #424

for noreturn-marked functions to return using longjmp.
