3b16efa1d1 miniobject: add lock functionality to GstMiniObject
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.

1be934f0dd miniobjects: pass copy, dispose and free function to gst_mini_object_init()
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.

12aefaa078 miniobject: remove the size field
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.

03cdd32b33 bufferlist: avoid reading past the array
When the foreach function told us to remove the buffer from the list, decrease
the length of the array or else we might read past the last item in the array.

f3b0d3cdbe init: add _get_type() functions
Remove gst_mini_object_register() and add a GST_DEFINE_MINI_OBJECT macro to
define a _get_type() function for the boxed miniobject.
Remove a bunch of custom _get_type() functions and replace them with the
miniobject macro.
Rename some _init method to _priv_*_initialize() like the rest of them.

Inspired by patch from Johan Dahlin and see bug #657603

We now have multiple memory blocks as part of the buffers and we can therefore
reduce the bufferlist to a simple array of buffers.

c4c06a2b88 bufferlist: Use a GQueue instead of a GList
Adding a buffer to the end of a GstBufferList is supposed to be a fast
operation, but it was not since the iterator does not advance its
nextpointer when adding buffers and GList does not have a tail pointer.
Using a GQueue to store the buffers makes it easier to add buffers to
the end of the list and this operation will now be much more efficient.

Adding an entire GList of buffers using
gst_buffer_list_iterator_add_list() will however have to iterate over
the list being added to be able to update the tail pointer in the
GQueue.

d41997040b gst: make _get_type() in gst/* thread safe
This is not really necessary here because everything is
initialized from gst_init() already but using G_DEFINE_TYPE()
removes some copy&paste boilerplate code.

a9d1a493a7 Fixes for -Wwrite-strings
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.

index.

27fb4ce76c bufferlist: add bufferlist code
Buffer lists are a means to manage disjoint buffers as one buffer. It's also
possible to put many of those buffers into a list.

The idea is that when support is added to various elements, we will be able to
more efficiently slice and dice buffers, reduce the amount of memcpy and also
reduce data passing overhead.

The implementation is kept simple on purpose, reusing all of the memory
management features we have for miniobjects and buffers.

Access to the bufferlist object is done with an iterator, which allows for
efficient iteration and modification of the list.

See #572285
