imp 0a15fd3fab Finish conversion to bus space and make ed MP safe. 
o Lock ed
o Fix extra newline in probe messages
o Eliminate gone.
o Make detach less-racy.
o Eliminate spl*
o Switch from timeout/untimeout to callout interface.
o Read/write card memory using bus_space calls.
o generalize readmem so that we don't need ifs in the code.
o Fix memory stuff to be consistant.
o Remove OLDCARD compat stuff.
o Mark interrupt as MPSAFE.

# sic, hpp not tested at all
# ISA and PCI attachments lightly tested
