Changes since 1.5: +5 -1 lines

several clean ups:
	- don't include eeprom support on sparc64.
	- work out if we are eeprom or openprom from the results of open()
	and/or ioctl(), rather than grovelling the kernel.
	- move all eeprom specific code to eehandlers.c
	- update manpage for sparc64 usage, remove delete -N switch

with these changes, eeprom(8) no longer needs to be setgid.
