Long over due checkpoint:
o register the hifn as handling DES and 3DES (no md5 or sha1 yet) depending
on whether the board is unlocked (none, half, or full)
o Fix many KNF nits
o print the amount of memory correctly and don't print the number of sessions
o set command and result buffer sizes correctly
o reclaim the descriptor rings so new commands and buffers can be added
o remove some bogus checks on the command buffer
o add new variables mac_process_len and crypt_process_len to hifn_command_t
o fix calculation in hifn_mbuf to generate the pa/len array for src/dst
o simplify the code for setting up the jump descriptor
o rework the hifn_intr routine to interrupt at IPL_IMP and simplify it's
results processing
o more to come...
