- 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.
- keep the case consistent between the actual name and what's referenced.
e.g, if it's `foo', don't use '.Nm Foo' at the start of a sentence.
- remove unnecessary `.Nm foo' after the first occurrence (except for
using `.Nm ""' if there's stuff following, or for the 2nd and so on
occurrences in a SYNOPSIS
- use Sx, Ic, Li, Em, Sq, and Xr as appropriate
