Subject: Re-enable memalign for Haiku

This had been disabled in 2011:
https://lists.ffmpeg.org/pipermail/ffmpeg-cvslog/2011-June/038362.html

If there are still problems with it we should rather fix them on Haiku
side.

Subject: libavutil: Forcibly enable use of pthread_setname_np.

Defining _BSD_SOURCE in here may not work if pthread.h
was already included, so just redeclare the method and
set the definition.
