Earlier, sc->samples_per_frame was used for setting the frame size,
but all files don't have that set properly. The frame size is a
known constant for these codecs.

If frame_size isn't set, the mov/3gp muxer refuses to mux it.

This fixes stream copy of audio from
https://roundup.libav.org/file1248/Video_With_AMR-NB_Audio.3gp
to another 3gp file (roundup issue 2468).

The vertical scaler handles 2 rows at a time and thus requires
alignment by 2, or else it'll read invalid memory and result in
corrupt output.

Fixes the following conformance suite samples:
HCBP1_HHI_A.264, HCBP2_HHI_A.264, HCMP1_HHI_A.264 (main)
HCHP1_HHI_B.264, HCHP2_HHI_A.264, HCHP3_HHI_A.264 (frext)

These packets are valid packets, and consist of 1 byte (which
contains the mode bits).

This had been analyzed and reported by Igor Levin, igor d levin comverse com.

Saves a bit on space and relocations.
Also makes the (very hackish) lossless conversion check
in ffmpeg.c work reliably.

If the application hasn't set up mutex callbacks, we set up
our own using pthreads (or w32pthreads).

Issue an error and return a more meaningful error code in case the
maximum number of registered filters has been reached.
This is better than silently ignore the error, improve feedback.

Change the libutvideo wrapper name to "libutvideo", as
it currently conflicts with the native utvideo decoder's
name of "utvideo".
