Internal (onboard) programming was the only feature which could not be disabled

Make various pieces of code conditional on support for internal
programming. Code shared between PCI device programmers and onboard
programming is now conditional as well.

It is now possible to build only with dummy support:
make CONFIG_INTERNAL=no CONFIG_NIC3COM=no CONFIG_SATASII=no
CONFIG_DRKAISER=no CONFIG_SERPROG=no CONFIG_FT2232SPI=no

This allows building for a specific use case only, and it also
facilitates porting to a new architecture because it is possible to
focus on highlevel code only.

Note: Either internal or dummy programmer needs to be compiled in due to
the current behaviour of always picking a default programmer if -p is
not specified. Picking an arbitrary external programmer as default  
wouldn't make sense.

Build and runtime tested in all 1024 possible build combinations. The
only failures are by design as mentioned above.
