libopus: Remap channels using libopus' internal remapping.
This way we can directly remap channels from Opus' channel order to
libav's internal channel order, instead of mapping channels from
Opus' order to Vorbis' order then to libav's order.
http: Increase buffer sizes to cope with longer URIs
Use the MAX_URL_SIZE define where applicable. Increase buffer
sizes for all buffers that need to fit a long pathname - buffers
that need to fit only the hostname (and other short strings, but
not the pathname - such as "headers" in http_connect) are kept
at 1024 bytes for now.
Also increase the max line length in http_read_header, since it
might need to contain a full url for Location: redirects.
Anonymous typedef structs prevent forward declaration, this
change gives the AVIOContext and AVIOInterruptCB structures
a name. These structures are now in line with other common
structures such as AVFormatContext and AVCodecContext.

Do not use rlelen field for buffer size in init_get_bits, it is
only the size of the data for the first field.
Since it is not reliable, just use the size of the whole buffer.
Additional comments add removal of unused rlelen variable by
Reimar Döffinger.

libfdk-aac: Allow setting VBR modes via a private option
This avoids using the global_quality field and QSCALE flag for
passing the VBR modes, since the value range of the global_quality
field doesn't really map cleanly to this codec's VBR modes.

libfdk-aac: Warn the user that the VBR modes are unsupported
These modes were not originally exposed by the library at all.
In practice, only a few of them work for each sample rate/profile
combination, and they don't work at all for the more uncommon
sample rates.
sipr: fall back to setting mode based on bit_rate.
Not all applications (e.g. MPlayer) set block_align, and
when using a different demuxer it might not even be
easily available.
So fall back to selecting mode based on bit rate as before
if block_align has not useful value.
It can't be worse than failing to decode completely.

ARM: align PIC offset pools to 4 bytes
When building Thumb2 code, the end of a function, where the PIC
offsets are placed, need not be aligned. Although the values
are only accessed with instructions allowing unaligned addresses,
keeping them aligned is preferable.

motion_est: fix use of inline on extern functions
Inline functions declared without extern do not provide an external
definition in standard C99. This code only works because most
compilers do not implement the inline semantics correctly. With a
stricter compiler, linking fails with unresolved references to these
functions.
Declaring the functions extern inline works correctly with some
compilers while some others still fail to create external definitions.
For maximum portability, create a static inline version with an
externally visible wrapper for ff_get_mb_score. ff_epzs_motion_search
is so large that no sane compiler inlines it anyway, so there the
inline keyword can simply be dropped with no effect.
Frames described by this grouping are the starter of a closed or
an open GOP.
This is useful for open GOP of H.264 stream which is not described
by sync sample atom.
