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.

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.

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.

acdb4ce03d gstvalue: expose gst_value_deserialize_with_pspec()
Typing hints can only be passed to gst_value_deserialize()
through the type of the passed-in value. This means deserialization
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
value.

This allows for example passing arrays of flags through the
command line or gst_util_set_object_arg, eg:

foo="<bar,bar+baz>"

bbca6b1ddf meta: expose API to register and create custom meta
Custom meta is backed by a GstStructure, and does not require
that users of the API expose their GstMeta implementation as
public API for other components to make use of it.

In addition, it provides a simpler interface by ignoring the
impl vs. api distinction that the regular API exposes.

This new API is meant to be the meta counterpart to custom events
and messages, and to be more convenient than the lower-level API
when the absolute best performance isn't a requirement.

1206a60bac bus: clear bus->priv->signal_watch immediately when the source is removed
There is a race-condition that can trigger the assertion in
gst_bus_add_signal_watch_full():

If gst_bus_add_signal_watch_full() is called immediately after
gst_bus_remove_signal_watch() then bus->priv->signal_watch may still be set
because gst_bus_source_dispose() or gst_bus_source_finalize() was not yet
called.
This happens if the corresponding GMainContext has the source queued for
dispatch. In this case, the following dispatch will only unref and delete
the signal_watch because it was already destroyed. Any pending messages
will remain until a new watch is installed.

So bus->priv->signal_watch can be cleared immediately when the watch is
removed. This avoid the race condition.

5edc20188a caps: Don't assert in fixate() on EMPTY/ANY caps and document EMPTY/ANY behaviour on more functions
fixate() will return empty caps if it gets empty caps passed and assert
early if any caps are provided as there's no meaningful way of fixating

truncate() and simplify() will return the input caps in case of

behaviour.

Also add tests for this and a few other operations behaviour on
empty/any caps.

Keep the ANY caps empty internally when appending and merging

407e32588d caps: fix is_strictly_equal
Fixed gst_caps_is_strictly_equal() to take into account whether either of
the caps are ANY caps. Previously, two ANY caps could be considered not
strictly equal if one of them still contained some remnant *internal*
structure (this can happen if an ANY caps has emerged from an append or
merge operation). Also, an ANY caps with no remnant internal structures
was considered strictly equal to an EMPTY caps. Similarly, a non-ANY caps
was considered strictly equal to an ANY caps if its remnant internal
structures happened to match.

Also changed gst_caps_is_fixed to take into account that an ANY caps
should not be considered fixed even if it contains a single remnant
internal fixed structure. This affects gst_caps_is_equal(), which uses a
separate method if both caps are fixed. Previously, this meant that a
non-ANY fixed caps was considered equal to an ANY caps if it contained a
single matching remnant internal structure.

Added some tests for these two equality methods, which covers the above
examples, as well as asserts existing behaviour.

72daeee2c4 gstinfo: Add new API for getting debug log lines
If you're using a custom log handler, you had to reverse-engineer the
debug log format and create your own format function. Now, you can
call `gst_debug_log_get_line()` and it will return a string (without
ANSI escape color codes) representation instead.

This is useful in situations when you need to log the ordinary
gst_debug log to a resource that can't be opened as a `FILE` handle.

Also includes a test.

0cb3940c94 bin: Add method to find elements by factory name
A common use case of a dynamically built pipeline is that you want to
(conditionally) find a certain element, e.g. the `rtpbin`s in a
`uridecodebin`. If that element has a fixed name inside its parent bin
(and only has a single instance) this can be easily done by
`gst_bin_get_by_name()`.

If there are multiple instances of the element however, you can only use
`gst_bin_iterate_all_by_interface()`, but this doesn't work if you don't
have the specific `GType` (which is often the case, due to plugins being
dynamically loaded). As such, another fallback could be to use the
well-known name of the element's factory (in case of our example, this
is of course `"rtpbin"`).
