Remove the ancient
"If building for IRIX, compile a program that does absolutely nothing."
#ifndef silliness.

A bit of "String Cleaning" for the ol' configure.ac.
Mmmm, smell the freshness!

Removed/updated some more anachronisms.

fix the usage of AM_INIT_AUTOMAKE and AC_INIT. Use the correct form of AC_INIT_AUTOMAKE
to specify automake 1.6.3 as the minimum version required. Rename configure.in
to configure.ac

Don't print the warning message about chroma supersampling for 444. Reject the 1 and 4 plane formats.

Update the jpeg2yuv manpage with the -R option and remove the comment about
jpeg2yuv not rescaling the chroma to the 16-235 range.

Add AC_PREREQ(2.57) to insist on autoconf 2.57 at a minimum. Slightly earlier
versions _may_ work - if folks are using 2.53 and it works then we can update the
the configure.in file.

Add the original INSTALL file as INSTALL.real so that autoreconf will not
overwrite INSTALL with the generic installation instructions.

Begin the deprecation process for autogen.sh in favor of autoreconf -f -i

- changed blocksize to 8x8 overlapped

- disarmed other chroma-modes than 420 (temporarily, until all memory
glitches are fixed)

- fixed memory-bugs (writing into memory not owned by the deinterlacer)
by 4:2:0 routines (so this should be running on a Mac ?!) electric-
fence does only moan about *reading* out-off-bounds, now... I'm not
sure how to fix this (and if it's really needed)...

- non-linear intra-field interpolation (which looks better than sinc as
we don't have alias-free source-images ...

- motion-compensation limited to power of 2 for y-axis (avoids some
alias-problems -- and adds flicker, sometimes ... hmm)
