WL#4481: Falcon Engine - Make hash table sizes power of two

Affects: WorkLog-3.4 — Status: Complete — Priority: Medium

Falcon hash table sizes are not currently forced to a power of two.  Thus the
accessors must use mod and div operations.

This change will make the hash tables sized to a power of two and use bit
masking operations for accessors.  Div and Mod operations take many CPU clock
cycles to complete.  Bit masking operations are relatively cheap.  This will
reduce the lock hold times and increase performance.
