When appending/prepending tags, avoid re-creating (and copying) lists if we already
have one and instead just append/prepend the GValue to the list.

Facilitate GstBuffer -> GstSample transition for some tags,
could be hard to catch otherwise when creating tags, since
it'll only be apparent later when someone tries to read the
tags.
This specifies if a given taglist applies to the complete
medium or only this specific stream. By default a taglist
has a stream scope.
Fixes bug #677619.
Move the locking methods from GstMemory to GstMiniObject.
Add a miniobject flag to enable LOCKABLE objects. LOCKABLE objects can
use the lock/unlock API to control the access to the object.
Add a minobject flag that allows you to lock an object in readonly mode.
Modify the _is_writable() method to check the shared counter for LOCKABLE
objects. This allows us to control writability separately from the refcount for
LOCKABLE objects.
So mini objects don't have to poke into the GstMiniObject part
of the structure. Saves lines of code, and seems slightly cleaner.
We don't have proper OO hierarchies or methods here after all.
These changes are to clean up syntax issues such as missing colons,
missing spaces, etc., and minor issues such as argument names in
headers not matching the implementation and/or documentation.
The size field is used by subclasses to store the total allocated size of the
memory for this miniobject. Because miniobject doesn't really do anything with
this field we can move it to the subclasses.
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).

No one uses this or should ever need to use it, since
the size is architecture-specific anyway. If normal
integers don't do, one should use 64-bit integers.
Hide the fact that it's just a GstStructure from the API. We
may want to change this in future (e.g. to add refcounting).
Also, it caused problems for bindings (though that's mostly
the way we typedefed it to GstStructure).
We never get a tag name quark from a caller, it's always a
string, from which we'll try to look up our tag info in the
hash table, so change the hash table key from quark to string.
Avoids a bunch of pointless string => quark lookup in the
global quark table. We need to do an extra string => quark
conversion now when we copy a taglist, but in that case we're
in a slow path anyway.
