ddfcc28c8b gst/buffer: add a new function for wrapping GBytes
One restriction on the GBytes is that the data cannot be NULL as this is
explicitly forbidden by GstMemory.

c1f2775dcb gstbuffer: fix GstParentBufferMeta GType name
The alias define GST_TYPE_PARENT_BUFFER_META_API_TYPE is wrong and
breaks the usage of gst_buffer_get_parent_buffer_meta().

This patch fixes the GType alias and make another alias to keep the API
compatibility guarded by GST_DISABLE_DEPRECATED.

Also added a unit test.

96eaeadc0f gstbuffer: add gst_buffer_copy_deep
A variant of gst_buffer_copy that forces the underlying memory
to be copied.

This is added to avoid adding an extra reference to a GstMemory
that might belong to a bufferpool that is trying to be drained.
The use case is when the buffer copying is done to release the
old buffer and all its resources.

38b96e6c8c buffer: improve the buffer memory methods
gst_buffer_take_memory -> gst_buffer_insert_memory because insert is what the
method does.
Make all methods deal with ranges so that we can replace, merge, remove and map
a certain subset of the memory in a buffer. With the new methods we can make
some code nicer and reuse more code. Being able to deal with a subset of the
buffer memory allows us to optimize more cases later (most notably RTP headers
and payload that could be in different memory objects).
Make some more convenient macros that call the more generic range methods.

bb876588ac buffer: unify buffer merge methods
Add gst_buffer_append() which appends the memory blocks from one buffer to
another. Remove the old inefficient _merge() and _join() methods which forced a
premature memcpy in most cases.
Remove the _is_span() and _span() methods they are not needed anymore now that
we can _append(). Merging and spanning will be delayed until mapping or maybe
not at all when the element can deal with the different memory blocks.

85c9543841 memory: group allocation parameters in a struct
Group the extra allocation parameters in a GstAllocationParams structure to make
it easier to deal with them and so that we can extend them later if needed.
Make gst_buffer_new_allocate() take the GstAllocationParams for added
functionality.
Add boxed type for GstAllocationParams.

edd2ffe4d4 memory: Add 0 padding
Change gst_allocator_alloc() so that we can also spicify flags and padding.
Add 2 new flags to mark the memory 0 prefixed/padded. This allows us to
remove some resizes in the base classes.
When allocating memory, memset prefix and padding with 0 when the flags tell
us to.
On resize, clear the zero padding flags if we can't guarantee the memory is
still 0 filled.
Update tests.

c6a1bed1ad memory: more work on refcount and writability
Rename _is_writable() with _is_exclusive because the writability does not depend
on the amount of references to the memory object anymore.
Add accessor macros for the memory flags.
Rename the GstBuffer _peek_memory() method to _get_memory() and return a
reference to the memory now that we can do this without affecting writability
of the memory object. Make it possible to also make this function merge the
buffer memory.
Add methods to replace memory in a buffer. Make some convience macros for the
buffer memory functions.
Fix unit tests.

Alow resize to 0 bytes.
Do clipping correctly.
Add more unit tests. Also add a failing test: when we resize to 0 and then
try to resize back to the original size it fails because the memory was
removed.

54fd50bfe1 buffer: add index to _take_memory()

certain offset. This is mostly interesting to prepend a header memory block to
the buffer.

c4751ec8c1 Revert "context: use context on buffers instead of caps"
This reverts commit 9ef1346b1f.

Way to much for one commit and I'm not sure we want to get rid of the pad caps
just like that. It's nice to have the buffer and its type in onw nice bundle
without having to drag the complete context with it.
