Various places in the flashrom source feature custom parameter extraction from programmer_param

This led to wildly differing syntax for programmer parameters, and
it also voids pretty much every assumption you could make about
programmer_param. The latter is a problem for libflashrom.

Use extract_param everywhere, clean up related code and make it more
foolproof. Add two instances of exit(1) where we have no option to
return an error. Remove six instances of exit(1) where returning an
error was possible.

WARNING: This changes programmer parameter syntax for a few programmers!

Corresponding to flashrom svn r1070.
