322caf880d structure: Add support for brackets as nested structures/caps specifiers 
This introduces a more human friendly syntax to specify nested
structures It does so by using 2 different markers for opening and
closing them instead of abusing quotes which lead to requiring an insane
amount of escaping to match nesting levels.

The brackets (`[` and `]`) have been chosen as they avoid complex
constructions with curly brackets (or lower/higher than signs) where you
could have structures embedded inside arrays (which also use curly
brackets), ie. `s, array=(structure){{struct}}` should be parsed as an
array of structures, but the cast seems to imply something different. We
do not have this issue with brackets as they are currently used for
ranges, which can only be casted to numeric types.

This commit does not make use of that new syntax for serialization as
that would break backward compatibility, so it is basically a 'sugar'
syntax for humans. A notice has been explicitly made in the
documentation to let the user know about it.

17feeb1bd6 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

b6df564251 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.

c884f4c124 taskpool: modify transfer annotations for push() and join() 
While the default implementation passes NULL around as the
task handle, other implementations can only provide a safe
API by having that handle map to a refcounted opaque type.

While what's passed around is a gpointer, a valid transfer
type annotation has informative value.

e74040b41e 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.

41677a526b devicemonitor: Stop only the already started providers 
If a device provider fails to start (for instance the pulseaudio provider unable
to connect to the PulseAudio daemon) then the monitor should not keep track of
it in its `started` providers list. Otherwise a false positive critical warning
would be raised.

This patch also switches the started_count type from bool to int, for
consistency. This is a counter, after all.

e600c85aee aggregator: Include min-upstream-latency in buffering time 
While we can fixe the upstream latency using the min-upstream-latency, we
are now forced to use queues (hence more thread) in order to store the pending
data whenever we have an upstream source that has lower latency.

This fixes the issue by allowing to buffer the fixed upstream latency. This is
particularly handy on single core systems were having too many threads can
cause serious performance issues.
