Add opaque programmer registration infrastructure

Browse Source 
An opaque programmer does not allow direct flash access and only offers
abstract probe/read/erase/write methods.
Due to that, opaque programmers need their own infrastructure and
registration framework.

Corresponding to flashrom svn r1459.
