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.

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.

Otherwise negative values will sets all of the 64 bits due to two's
complement's definition of negative values.
Also add a test for negative int ranges.
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.

Wrap caps strings so that it can handle serialization and deserialization
of caps inside caps. Otherwise the values from the internal caps are parsed
as if they were from the upper one
https://bugzilla.gnome.org/show_bug.cgi?id=708772
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.

This re-uses existing code and makes sure we properly serialise
and deserialise datetimes where not all fields are set (thus
fixing some warnings when serialising such datetimes).
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).

This changes some APIs in compatible ways:
- Some functions now take "const char *" arguments, not "char *"
- Some structs now have "conts char *" members, not "char *"
The changes may cause warnings when compiling with the right warning
flags. You've been warned.
Also adds -Wwrite-strings as a warning flag in configure.ac.

Don't forbid the empty string "" in generic structures, only in taglists.
Properly allow the NULL string by adding special cases for serialising
and deserialising it. prop1=(string)NULL is the NULL string,
prop1=(string)"NULL" is the actual string with the value "NULL"

_gst_trace_on is already provided by gsttrace.h, no need to declare
it ourselves.

Properly declare 'buffers', 'check_cond', 'check_mutex' extern
and define them in gstcheck.c instead of having every .c file whcih
includes gstcheck.h be defining its own copy and relying on symbol
interposing to marry them all, which doesn't work on Solaris.

Don't define 'buffers' locally, it comes from libgstcheck.

Added GstStructure to gst_value_table and its related functions.
Changed gst_structure_to_string to print ';' in the end.
Changed gst_caps_to_string to not print ';' beteween its
fields (structures) anymore and remove the lastes ';' from latest
structure. Now it is possible to have nested structures.
In addition, backward compatibilty is assured by accepting '\0' as
end delimiter. Fixes: #487969.
