add qispowerof2() to qfunc.c, improve log2() code

Browse Source 
Change zispowerof2() interaface to take a FULL ptr as the 2nd arg:
zispowerof2(ZVALUE z, FULL *log2).

Added qispowerof2(NUMBER *q, NUMBER **qlog2) to qfunc.c.

Change log2() builtin to use the new qispowerof2() internal interface.

Update LIBRARY to reflect the new zispowerof2() internal interface
and the new qispowerof2() internal interface.
