be394968c8 resample: add initial padding explicitly 
This simplifies the code, since we do not have to deal with a possibly
negative source index anymore.

b9dea23766 resample: fix avresample_get_delay() return value 
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.

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.

1d86aa8b0f lavr: do not pass consumed samples as a parameter to ff_audio_resample() 
Since the resampler handles buffering of unconsumed samples internally, the
caller does not need this information.
