87fd35d59c tests: Add disjoint pad probe removal test.
Add a test that removing a blocking probe on events when there
is a different blocking probe on buffers releases the data flow.

da3886acac pad: Improve the documentation for GstPadProbeReturn.
Explain that GST_PAD_PROBE_PASS will pass data even if there is
another pad probe that says to block, and that GST_PAD_PROBE_REMOVE
passes data and potentially unblocks the pad.

170f694198 pad: Fix for multiple blocking probes interaction.
Change the way the marshalled flag in the internal ProbeMarshall state
is handled when iterating over pad probes so that it only counts
probes that still exist and would be called when retrying.

This improves the way that removing a blocking probe works when
there are multiple blocking probes for different conditions (data vs
events for example).

As a side-effect, probes aren't put into the the called_probes array
unless they actually match the current probe type and would be called,
potentially reducing the number of hooks that get stored in the
called_probes array, and the cost of the looping check on retries.

5eba2b83b7 gstvalue: preserve parse behaviour with warning
Preserve the previous behaviour where:
    name, val="5";
passed to gst_structure_from_string would have resulted in an int value,
rather than a string, despite the quote marks.

This will be changed to being interpreted as a string in the future, but
for the time being we will issue a warning about this to give users time
to fix their code to no longer rely on this bug.

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.
