0ac8ff618c avresample: Reallocate the internal buffer to the correct size 
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.

f1c2915ce1 lavr: remove automatic context close/open for resampling compensation 
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.
