allocators: dmabuf: allow testing allocator type
...
In decide_allocation function some element may when to test the proposed allocator.
For example like this:
if (gst_query_get_n_allocation_params (query) > 0) {
GstAllocator * allocator;
GstAllocationParams params;
gst_query_parse_nth_allocation_param (query, 0, &allocator, ¶ms);
if (g_strcmp0(allocator->mem_type, GST_ALLOCATOR_DMABUF) == 0)
GST_DEBUG("got dmabuf allocator");
else
GST_DEBUG("got an other allocator");
}

dmabuf: Use the fallback GstMemory copy function instead of our own
...
dup() on a dmabuf only gives a new handle, not a copy, thus doesn't
do what copy() is supposed to do.

allocators: Add dmabuf-based GstMemory and GstAllocator
...
Create new GstMemory and GstAllocator base on dmabuf.
Memory is not allocated/freed by userland but mapped/unmmaped
from a dmabuf file descriptor when requested.
This allocator is included in a new lib called libgstallocators
