7b0e4f27fb memory: make _new_wrapped take user_data and notify
Make it possible to configure a GDestroyNotify and user_data for
gst_memory_new_wrapped() this allows for more flexible wrapping of foreign
memory blocks.

a521252845 Add new GstMapInfo
Use a structure to hold info about the mapping. The application then keeps track
of this state and we can use it to unmap the memory again later.

12757e604a adapter: automatically unmap on clearing
When _clear gets called between _map and _unmap, buffers
will be unreffed. If the adapter was mapped, memory leaks
may occur.
While calling _clear between _map and _unmap does not seem
like such a great idea, this is possible in the audio
encoder base class, as _clear may be called in _finish_frame.
Since the audio encoder relies on flushing to keep track of
timestamps, delaying flushing till after handle_frame seems
dangerous.
So, we unmap on clear, as the next unmap will do nothing.
This makes _clear safe to call between _map and _unmap,
while avoiding leaking the mapped buffer.

f33b1397d3 adapter: fix return type of _map() to gconstpointer
Fixes compiler warnings on OSX:
gstadapter.h:82: warning: type qualifiers ignored on function return type
gstadapter.c:412: warning: type qualifiers ignored on function return type

const gpointer is not the same as gconstpointer or const void *.

54fd50bfe1 buffer: add index to _take_memory()
Add an index to gst_buffer_take_memory() so that we can also insert memory at a
certain offset. This is mostly interesting to prepend a header memory block to
the buffer.

27284628e4 optimisation : Use g_object_newv where possible.
This avoids:
* triple-checking for the GType when type-checking is enabled (see #597260)
* Avoids going through an expensive no-argument checking which landed in
  glib-2.22
* Avoids going through 2 extrac functions (g_object_new -> g_object_new_valist)

79c8e24885 docs: fix API docs for gst_{adapter|byte_reader}_masked_scan_uint32
Clarify byte reader docs a bit: offset is relative to the current
position of the reader, not to the start of the data. Also, the
examples in both the adapter docs and the byte reader docs have
the mask and pattern arguments swapped (see #587561). Spotted
by Carl-Anton Ingmarsson.

c74c3bf1b3 adapter: fix _masked_scan_uint32() at boundaries
gst_adapter_masked_scan_uint32 could return values smaller than offset
if the first byte(s) of the mask are 0 and the pattern matches the
beginning of the adapter.
Added examples to documentation of gst_adapter_masked_scan_uint32().
Also added some more masked boundary tests.
