1a8dfdfc54 Introduce gst_element_request_pad_simple
The name `gst_element_get_request_pad()` is confusing to people
learning GStreamer. `gst_element_request_pad_simple()` aims at
providing the exact same functionality, while making it more
explicit it is a simplified `gst_element_request_pad()`.

`gst_element_request_pad_simple()` is consistent with other
functions such as `gst_element_seek_simple`.

This commit deprecates `gst_element_get_request_pad()` so that a
compilation warning is emitted when used and incite developers
to use the more explicit `gst_element_request_pad_simple()`.

445df0c799 gstvalue: make gst_string_unwrap less strict
Allow a string in gst_string_unwrap to include unescaped characters that
are not in GST_STRING_IS_ASCII. This extra leniency allows
gst_structure_from_string to, e.g., receive
    name, val=(string)"string with space";

Note that many gst tests, and potentially users, exploited this behaviour
by giving
    name, val="string with space";
i.e. without the (string) type specifier. This was allowed before
because, without a type specifier, the string was passed to
_priv_gst_value_parse_string with unescape set to TRUE, *rather* than
being sent to gst_string_unwrap. This caused a difference in behaviour
between strings that are or are not preceded by (string). E.g.
    name, val=(string)"string with space";
would fail, whilst
    name, val="string with space";
would not. And
    name, val=(string)"\316\261";
would produce a val="α", whereas
    name, val=(string)"\316\261";
would produce a val="316261" (a bug).

The current behaviour is to treat both of these cases the same, which is
desirable. But in order to not break potentially common usage of this
discrepancy (it was in our own tests), the best option is to make string
parsing less strict in general.

New behaviour would be for
    name, val=(string)"string with space";
to pass and give val="string with space", and
    name, val="\316\261";
would produce a val="α".

Also changed deserializing string test to expect successes where
previously a failure was expected.

In a similar way, this also effected the deserializing of GstStructure,
GstCaps, GstTagList and GstCapsFeatures. So, now
    name, val=(structure)"sub-name, sub-val=(string)\"a: \\316\\261\";";
will also pass and give sub-val="a: α". Note that the quote marks
and backslash still need to be escaped for the sub-structure, but other
characters need not be.

454b121ff1 value: add serialize-deserialize tests

7f267395a6 structure: don't unescape values before deserializing
No longer call _priv_gst_value_parse_string with unescape set to TRUE
before passing a value to gst_value_deserialize in
_priv_gst_value_parse_value. This latter function is called by
gst_structure_from_string and gst_caps_from_string.

When gst_structure_to_string and gst_caps_to_string are called, no
escaping is performed after calling gst_value_serialize. Therefore, by
unescaping the value string, we were introducing an additional operation
that was not performed by the original *_to_string functions. In
particular, this has meant that the derialization functions for many
non-basic types are incomplete reverses of the corresponding
serialization function (i.e., if you pipe the output of the
serialization function into the deserialization function it could fail)
because they have to compensate for this additional escaping operation,
when really this should be the domain of the deserialization functions
instead.

Correspondingly changed a few deserialization functions.

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.
