Do not crash if the input format is not allocated yet.

avio_close checks by itself for NULL condition.

The missing headers are required for errno and for strerror.

Windows CE doesn't have neither mkdir nor _mkdir officially (only
CreateDirectoryW), but mingw32ce has compat wrappers with these names
(declared in io.h since direct.h is unavailable).

This muxer splits the output from the ismv muxer into individual
files, in realtime.

The same can also be done by the standalone tool ismindex, but this
muxer is needed for doing it in realtime (especially for live
streams that need extra handling for updating the lookahead fields
in the fragment headers).

Using this muxer, one can deliver live smooth streaming from a
normal static file web server. (Using ismindex, one can deliver
premade smooth streaming files from a static file web server,
or prepare files for serving with IIS.)

Everything written with this bitstream writer is 8/16 bit units

Currently the size header of the generated DHT section is
incorrect, making the mjpeg decoder just skip it. Since the
written huffman tables are the default ones, this failure had
gone undetected.
