patch #6074: added support for crossbow's MIB510 programmer
* avrdude.conf.in: Add entry for mib510.
* stk500.c: Add special hooks to handle the MIB510 programmer.
It mostly talks STK500v1 protocol but has a special hello and
goodbye sequence, and uses a fixed block size of 256 bytes.
* doc/avrdude.texi: Document support for mib510.
