Allow more control to advanced MPEG encoding application
Summary: exposed inner steps inside SeqEncoder::EncodeStream() to user
allowing finer control.

SeqEncoder::EncodeStream() currently parses image stream using 'pull'
method, calling reader from inside the long loop.

target_bits can be int instead of int32_t. Seems cygwin's implementation of
min() is broken somehow.

level 0 optimization suggested by Burkhard Plaum

Add support for model 15 Intel cpus (nocona x86_64)

Sigh, seems a lot of interlacing info being passed around but never placed in
the output file. For Quicktime files use the interlacing info to add the 'fiel'
atom to the file. After this is done Quicktime Player app will recognize and
play the file.

Might as well enable the program with a warning.

Fix memory leak when reading AVI files. IF libquicktime support was present
the buffers for quicktime handling would be allocated even if AVI was the
input format. Then when the return was done out of the avi logic the buffers
were not free'd.

jpeg2yuv doesn't see EOF when reading filenames from stdin
The jpeg2yuv command mjpegtools-1.9.0rc2 does not properly detect the end
of the list of input files passed via stdin. The example command mentioned
in the manual page

$ls *jpg | jpeg2yuv -f 25 -I p > result.yuv

never returns and keeps on writing data to result.yuv until the filesystem
is full.
