autodetection. Adds a symbolic name for autodetection.

ea4d5f4837 linux: use number of CPUs as automatic thread count
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.

aaf47bcde7 Drop ALT_ prefix from BITSTREAM_READER_LE name.
The prefix is a historic remnant that probably meant "alternative".
Now that the A32 bitstream reader has been dropped it makes no sense anymore.

4bf3c8f226 mov: Don't stick the QuickTime field ordering atom in extradata.
The 'fiel' atoms can be found in H.264 tracks clobbering the extradata.
MJPEG supports non field based extradata, and this data should be
preserved when copying.

f0e90e0035 lavc: make 100 the base for the micro version number.
This way ffmpeg can be distinguished from the fork by a user
application or a encoded file by a decoder.
The highest value micro had, in the past, that i could find, was 6
thus 100 should be safe.
