When no data was available both the buffer thread as well as
the main thread would block in select(), when data becomes
available both should move forward and as data is read in the
buffer thread the main thread would block in select() later
the read data was put in the fifo but the main thread still
would be blocked in select() until either the timeout or
another packet would come in.

This is solved in this commit by using a mutex and a condition
variable

The muxer depends on the id3v2 writing code, so link against it.

The demuxer depends on the RIFF codec tags code, so link against it.

The demuxer depends on code from mov.c, which in turn depends on
code from mov_chan.c, so link against it.

Prior to this a X bytes write could be seen as less than X bytes being
available if the check was done at an unfortunate moment.

A negative number of threads does not make sense and 0 is used for
autodetection. Adds a symbolic name for autodetection.

Use sched_getaffinity to determine the number of logical CPUs.
Limits the number of threads to 16 since slice threading of H.264
seems to be buggy with more than 16 threads.

This file does not use anything from get_bits.h but needs
intreadwrite.h.

The prefix is a historic remnant that probably meant "alternative".
Now that the A32 bitstream reader has been dropped it makes no sense anymore.
