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.

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.

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.

f17efc49c6 bitreader: Fix uninitialized variable compiler warnings
gcc doesn't notice that the check assertion macros will abort
further execution of the tests.

dd762eb49f bitreader: Add inlined and unchecked versions of the important functions
API: gst_bit_reader_skip_unchecked
API: gst_bit_reader_skip_to_byte_unchecked
API: gst_bit_reader_get_bits_uint16_unchecked
API: gst_bit_reader_get_bits_uint32_unchecked
API: gst_bit_reader_get_bits_uint64_unchecked
API: gst_bit_reader_get_bits_uint8_unchecked
API: gst_bit_reader_peek_bits_uint16_unchecked
API: gst_bit_reader_peek_bits_uint32_unchecked
API: gst_bit_reader_peek_bits_uint64_unchecked
API: gst_bit_reader_peek_bits_uint8_unchecked

This alone makes flacparse about 3 times faster.
