Rename programmer registration functions

Register_programmer suggests that we register a programmer. However,
that function registers a master for a given bus type, and a programmer
may support multiple masters (e.g. SPI, FWH). Rename a few other
functions to be more consistent.

Corresponding to flashrom svn r1831.
