Big clean up of Video for Linux backend. Removed old unused stuff from qcam 

and others including unused options and variables concerning direct port
access. Removed wcam license (no "substantial portions of code" are used any
more). Removed unuesed headers. Made lots of global variables local. Lots of
checks for null pointer dereferences and errors when opening files or using
ioctl/mmap. Added option to select grey or color mode. Added support for
different channels. Fixed lots of options.  Made sure ioctls are only used
when necessary.  Used vendor == "Noname".  Added ??? comments for suspicious
code.  Lots of minor fixes and cleanup. Added version number: 1.0-2.
