Doug Moore b0056b31e9 libkern: add ilog2 macro
The kernel source contains several definitions of an ilog2 function;
some are slower than necessary, and one of them is incorrect.
Elimininate them all and define an ilog2 macro in libkern to replace
them, in a way that is fast, correct for all argument types, and, in a
GENERIC kernel, includes a check for an invalid zero parameter.

Folks at Microsoft have verified that having a correct ilog2
definition for their MANA driver doesn't break it.
