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.

1afaa1680f adapter: add function to get a list of buffers 
Add a function to retrieve a list of buffers containing the first N bytes from
the adapter. This can be done without a memcpy and should make it possible to
transfer the list to a GstBufferList later.

7e23719a74 adapter: optimize progressive masked_scan 
Retain the last scanned buffer entry and offset, so we can resume buffer
scanning there in case of a typical progressive scan.
Also potentially optimize _copy subsequently occurring in that area.

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.

3e21ddf81f logging: add a performace log category

performance. Add FIXME-0.11 to some questionable categories.

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.

b23279e922 adapter: don't use realloc, it does a memcpy
