const-correctness fixes. (not yet Perfect, but it's getting there. :)

fix a couple of "char*"'s that should have been "unsigned char*"'s
(compiler warnings)

*** empty log message ***

Cleaned-up some pointer types:
o For Y'CbCr buffers, changed "unsigned char *" to the even less ambiguous
"uint8_t *", because that is precisely what they are.
o For y4m_read() and y4m_write(), changed "char *" to "void *", which more
accurately reflects their use as wrappers for read() and write().
(Internally, cast to "uint8_t *" in order to do some byte-wise pointer
arithmetic.)
o All other "char *" refer to character strings, and have been left alone.

Non-essential change,
just to see if a log message notification is produced.
(You can never have too much email.)

A first-swipe at getting commit-notifications automagically emailed to
developers. Since there is no existing "mjpeg-commit" list, right now
this just emails stuff to me.

Quick fix to allow deinterlace-only operation to succeed (output was being taken
from the denoising result buffer even if no denoising was performed).

mmap(PROT_READ|PROT_WRITE...) and minor casts to avoid compiler warnings.

Saner handling of avifile versions. Placed setup for such handling and
common avifile includes into new header file libavifile.h

cast for execvp to avoid compiler warnings.
