c711c8ed39 allocator: add gst_allocation_params_new()
This permits creating GstAllocationParams instances on the heap, which
is useful for language bindings that can handle GBoxed types.

09141c6e1f Use G_DEFINE_AUTOPTR_CLEANUP_FUNC unconditionally
Since we started depending on GLib 2.44, we can be sure this macro is
defined (it will be a no-op on compilers that don't support it). For
plugins we should just start using `G_DECLARE_FINAL_TYPE` which means
we no longer need the macro there, but for most types in core we don't
want to break ABI, which means it's better to just keep it like it is
(and use the `#ifdef` instead).

8983cce9f6 gst: GST_EXPORT -> GST_API
We need different export decorators for the different libs.
For now no actual change though, just rename before the release,
and add prelude headers to define the new decorator to GST_EXPORT.

92d3246f76 gst: mark symbols explicitly for export with GST_EXPORT
One omission: gst_allocator_sysmem_get_type() was
exported but never in any public header file.

bd9ea8d18f doc: Fix Since: marks
There was few Since: mark missing their column. Also unify the way
we set the Since mark on enum value and structure members. These
sadly don't show up in the index.

d61ba38118 memory: provide a mem_map_full that takes the GstMapInfo
Follow up of 7130230ddb

Provide the memory implementation the GstMapInfo that will be used to
map/unmap the memory.  This allows the memory implementation to use
some scratch space in GstMapInfo to e.g. track different map/unmap
behaviour or store extra implementation defined data about the map
in use.

7130230ddb memory: provide a mem_unmap function that takes the flags to unmap
There are gstmemory's available that operate in two memory domains
and need to ensure consistent access between these domains.

Imagine a scenario where e.g. the GLMemory is mapped twice in both
the GPU and the CPU domain.  On unmap or a subsequent map, it would
like to ensure that the most recent data is available in the memory
domain requested.  Either by flushing the writes and/or initiating a
DMA transfer.  Without knowing which domain is being unmapped, the
memory does not know where the most recent data is to transfer to
the other memory domain.

Note: this still does not allow downgrading a memory map.

a2027b5e9b allocator: remove user_data from alloc vmethod
Remove the user_data from the alloc vmethod. Subclasses that implement a new
alloc function can also implement their own vmethod to pass extra arguments. We
can then also require that custom allocators implement an alloc function so that
gst_allocator_alloc() always works.

f362f643ac memory: Make GstAllocator a GstObject
Make GstAllocator a GstObject instead of a GstMiniObject, like bufferpool.
Make a new gstallocator.c file. Make a GstAllocator subclass for the default
allocator.
