extend the if_ethersubr.c crc functions to support updating a running
crc in addition to the existing "oneshot" mode and use them to replace
ieee80211_crc_update() with the new ether_crc32_le_update(). Saves 1k
kernel bss + some code.
Mark the new ether_crc32_[lb]e_update functions as __pure for a
~25x speedup (on my i386 at least).
