qt-faststart is terribly slow when the input file and the output file
are on a slow disk like a SD card. By increasing the copy_buffer from
1K to 32M I decreased the processing time on a sample file from
1600 seconds to 4 seconds. The timing difference is during 'copying
rest of file'.

It is all dead and rotting code.
Also, move yuvcmp.c to tools. Its license is non-existent, however,
and should be clarified.

The missing headers are required for errno and for strerror.
This fixes building of this tool on mingw32ce.

PATH_MAX is not necessarily available on all systems, e.g. it's
normally not available on MSVC, and is not guaranteed to defined
on a POSIX system either.

This takes care of null-terminating the buffer if it is too small,
which wasn't handled properly before.

Also change the snprintf size to use the full buffer, since
snprintf always null-terminates the buffer.

The Windows SDK in MSVC doesn't have mkdir, only _mkdir, and
MSDN says one should include direct.h to use it.

Make it possible to use the run bisect sub command. As with all
other ffbisect commands, revisions that do not contain the needed
tools are skipped.

This tool uses lavfi internal symbols not accessible in shared
libraries. TESTPROGS are linked statically to allow them use of
library internals not normally exported.
