Bug-Id: CID 1323180

Deprecated in 11/2012.

Fixes the corner case in which the internal buffer size
is larger than input buffer provided and resizing it
before moving the left over samples would make it write
to now unallocated memory.

This applies to every library where performance is not critical.

Optimized for the default filter length 16.

30% faster opus silk decoding.

Required for arch optimized resampling.

This simplifies the code, since we do not have to deal with a possibly
negative source index anymore.

The correct "next" input sample is not the first sample of the
resampling buffer, but the center sample of the filter_length-sized
block at the beginning.

Simplifies header dependencies by not including all other internal headers
in internal.h.

It adds unnecessary complication for insignificant usability improvement.
The user really should know if they'll need resampling compensation before
opening the context.

Note that only the documentation has changed. The current functionality will
still work until the next major bump.

Since the resampler handles buffering of unconsumed samples internally, the
caller does not need this information.

Based partially on implementation by Michael Niedermayer <michaelni@gmx.at> in
libswresample in FFmpeg. See commits:

This is a new library for audio sample format, channel layout, and sample rate
conversion.
