Add a new utility to deal with raw (headerless) 4:2:2 data from digital
(IIDC) cameras. The uncompressed 4:2:2 data is not '422 planar', instead it
is packed as either YUYV or UYVY. This program repacks the data into 4:2:2
planar and puts on the YUV4MPEG2 header and FRAME markers.

Use the latest jpeg-mmx (0.1.6). DV is quite popular these days so require
libdv (and libdv-devel for building).

0x30 is 48 not 40. Sigh.

aenc/subs.c was empty (entire contents ifdef'd out for years now). Clean up and
get rid of it.

Get rid of the warning:
yuvscaler.c:1191: warning: initialization makes integer from pointer without a cast

Technical note TN 2086 on Apple's site provided better compiler options for the
G5 based systems.

Fix the errors reported by gcc:
musicin.c: In function `get_params':
musicin.c:247: warning: long int format, int arg (arg 2)
musicin.c:324: warning: suggest explicit braces to avoid ambiguous `else'

avoid overflow in the average P (and B) frame size. This was observed when
there were 241817 P frames of ~18KB each. Basically 4GB (32bits) isn't
enough when building m2v files destined for a dual layer disk.

Fix was to use int64_t for the avg_frames array and then cast the average
size to (int). It is highly unlikely that the average frame size will
exceed an 'int'.

silly to include <math.h> twice ;)

Minor wording change (they instead of their).
