Remove a bogus warning when using segment_list_type csv.
The LIST_TYPE_EXT constant is only used internally, so it can
be removed when the feature (segment_list_type ext) gets removed.

Should also be faster (though I doubt that hardly ever matters
for the usage here).
Also remove the pointer copy. Since we do not need to reset the
pointer to the start of the string, it is not needed anymore.

This updated version does not deviate from previous behavior on default value of 'buffer_size'
I skipped porting 'sources', 'block' options for now as they're parsed seriously. So i added TODO remarks.

This is consistent with stdio and is what we want to do in all cases.
Fixes a bug in the voc muxer which didn't flush in write_trailer()
previously. This is the cause of the change in the test results.
This is used by avidemux, and is likely usefull to others too.

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
(except for a pair of 4 bit values), so using a bitstream writer
isn't necessary.

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.

If regularly parsing new chan atoms (as in rtpdec_qt), but the
chan atoms don't actually contain any channel layout, don't reset
the value that the caller has filled in (by guessing).

It is included for the open/read/write/close functions. On
MSVC, where this header does not exist, the same functions
are provided by io.h, which is already included.
On windows, these functions are provided by io.h. Make sure
io.h is included if it exists, regardless of the setmode
function.
