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>"

79374b8d94 value: Fix comparison of int/int64 ranges
ranges are only equal if:
* Their bounds are equal
* And their step value are equal *IF* they contain more than one value

109bdd0c25 value: Refactor parsing lists to allow trailing comas
Before that commit `{test, }` wouldn't be accepted as an array
because of the trailing coma, the commit fixes that.

At the same time, the code has been refactored to avoid special casing
the first element of the list, making `{,}` or `<,>` valid lists.

0dafe6e639 gstvalue: use value_nick for serialization
not value_name . This was causing incorrect launch lines to be
displayed by gst-device-monitor, and the deserialization code
below works with nicks.

1335110409 tests: fix tests when compiling with glib_checks=disabled
We won't be able to do ASSERT_CRITICAL, but the main body of the tests
are still valid, and given we ship GStreamer with this configuration, it
is important to be able to run some tests against it.

ad40c5cd36 value: add structure intersect/union/is_subset/fixate implementations
Allows proper usage of structures in structures in caps.  Subtraction
is not implemented due to complications with empty fields representing
all possible values.

The only implementation that doesn't delegate to the already existing
GstStructure functions is the union function.

f9e5178dd1 gstvalue: Add GstFlagSet type
GstFlagSet is a new type designed for negotiating sets
of boolean capabilities flags, consisting of a 32-bit
flags bitfield and 32-bit mask field. The mask field
indicates which of the flags bits an element needs to have
as specific values, and which it doesn't care about.

This allows efficient negotiation of arrays of boolean
capabilities.

The standard serialisation format is FLAGS:MASK, with
flags and mask fields expressed in hexadecimal, however
GstFlagSet has a gst_register_flagset() function, which
associates a new GstFlagSet derived type with an existing
GFlags gtype. When serializing a GstFlagSet with an
associated set of GFlags, it also serializes a human-readable
form of the flags for easier debugging.

It is possible to parse a GFlags style serialisation of a
flagset, without the hex portion on the front. ie,
+flag1/flag2/flag3+flag4, to indicate that
flag1 & flag4 must be set, and flag2/flag3 must be unset,
and any other flags are don't-care.

555e0211c8 gstvalue: only unwrap string delimited with "
Don't unwrap strings that start but don't finish with a double quote. If a
string is delimited by two quotes we unescape them and any special characters
in the middle (like \" or \\). If the first character or the last character
aren't a quote we assume it's part of an unescaped string.

Moved some deserialize_string unit tests because we don't try to unwrap strings
missing that second quote anymore.

3ea6b04c10 gstvalue: Fix comparision of double range
Checking twice the lower bound is great (you never know, it might change
between the two calls by someone using emacs butterfly-mode), but it's a bit
more useful to check the higher bound are also identical.

fb3b53328f value: Remove set-style bitmask intersection/union/subtraction functions
Set operations on the bitmasks don't make much sense and result
in invalid caps when used as a channel-mask. They are now handled
exactly like integers.

This functionality was not used anywhere except for tests.

c721d53773 Remove GST_TYPE_DATE, our own GDate type
Which we had to add because GLib didn't have it
back in the day. Port everything to plain old
G_TYPE_DATE, which is also a boxed type. Ideally
we'd just use GDateTime for everything, but it
doesn't support not setting some of the fields
unfortuntely (which would be very useful for
tag handling in general, if we could express
2012-01 for example).
