I found, that there is another leak in the alaw/ulaw encoders:
In pcm.c, function pcm_encode_init():

linear_to_alaw = av_malloc(16384); -> linear_to_alaw = av_mallocz_static(16384);
linear_to_ulaw = av_malloc(16384); -> linear_to_alaw = av_mallocz_static(16384);

I don't use the alaw/ulaw codecs (have my own implementations), so I cannot
make/test a patch.

Another question is, if there should be a function av_malloc_static().
av_mallocz_static initializes the memory with 0 (like calloc), but in this
case this isn't necessary since the whole table gets initialized anyway.
