gst_clear_*: Remove volatile from arguments
g_clear_pointer is not thread-safe and never was. GLib similarly removed
the volatile from g_clear_object in 2aacef39b1.

e35dc31fda structure: add gst_clear_structure()
Basically, you can use this instead of using gst_structure_free (which
needs to be preceded by a NULL-check).

Also fixes #275

6dba0d91ed gst_structure_to_string: display actual value of pointers
We used to always display "NULL" which was pretty confusing when
debugging.

eb329eec1c structure: add a todo comment

c21e219ed4 structure: Add get/set_array/list using GValueArray
This adds a binding friendly interface to get and set arrays
and list into GstStructure.

New API:
 - gst_structure_set_array
 - gst_structure_set_list
 - gst_structure_get_array
 - gst_structure_get_list

a3cfcbfede value: Always add the type name to elements when serializing arrays/lists
But only when serializing outside of GstStructures, because in case of
GstStructure the type is already preprended to the array/list and the
GstStructure API makes sure that they have the same "generic" type so
deserialization works properly.

This keeps serialization of GstStructures the same as before, and the
GstCaps unit tests already test for that. However when serializing
standalone arrays/lists get the types added now.

e1dc60524e dynamic types: Implement dynamic types in the registry
Implement GstDynamicTypeFactory as a new registry feature.

GstDynamicTypeFactory provides a way of registering a GType
into the registry, such that it will be registered as a dynamic
type when the registry is loaded, and then automatically loaded
if the type is needed during caps parsing.

This allows using non-core types in pad templates, by loading a
registry feature to create the GType on the fly.

10b78d872b tracerrecord: add a log record class
We use this class to register tracer log entry metadata and build a log
template. With the log template we can serialize log data very efficiently.
This also simplifies the logging code, since that is now a simple varargs
function that is not exposing the implementation details.

Add docs for the new class and basic tests.

Remove the previous log handler.

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.

154eefecc9 Don't compare booleans for equality to TRUE and FALSE
TRUE is 1, but every other non-zero value is also considered true. Comparing
for equality with TRUE would only consider 1 but not the others.

Also normalize booleans in a few places.

2759882379 introspection: add missing (nullable) annotations to return values
Support for (nullable) was added to G-I at the same time as nullable
return values.  Previous versions of G-I will not mark return values as
nullable, even when an (allow-none) annotation is present, so it is
not necessary to add (allow-none) annotations for compatibility with
older versions of G-I.

ffdefd7720 value: add GstTagList serialisation/deserialisation
So we can serialise/deserialise taglists inside structures,
which used to work automagically before because GstTagList
was just a typedef to GstStructure (same for the GType),
but now that it's a separate GType we need to register
explicit functions for this.

Helps with GDP stuff in pipelines/streamheader tests.
