Format copyright headers more consistently
The IJG convention is to format copyright notices as:
Copyright (C) YYYY, Owner.
We try to maintain this convention for any code that is part of the
libjpeg API library (with the exception of preserving the copyright
notices from Cendio's code verbatim, since those predate
libjpeg-turbo.)
Note that the phrase "All Rights Reserved" is no longer necessary, since
all Buenos Aires Convention signatories signed onto the Berne Convention
in 2000. However, our convention is to retain this phrase for any files
that have a self-contained copyright header but to leave it off of any
files that refer to another file for conditions of distribution and use.
For instance, all of the non-SIMD files in the libjpeg API library refer
to README.ijg, and the copyright message in that file contains "All
Rights Reserved", so it is unnecessary to add it to the individual
files.
The TurboJPEG code retains my preferred formatting convention for
copyright notices, which is based on that of VirtualGL (where the
TurboJPEG API originated.)

Overhaul the AltiVec vector loading code in the compression-side colorspace conversion routines. The existing code was sometimes overreading the source buffer (at least according to valgrind), and it was necessary to increase the complexity of the code in order to prevent this without significantly compromising performance.

Remove unneeded code; Make sure jccolor-altivec.o will be rebuilt if jccolext-altivec.c changes.
