BUG: missed removal of pointMesh/boundaryProcAddressing (fixes #3412)

COMP: restrict HashTable maxTableSize to int32 range

- avoids compiler warning about possible overflow (left-shift
  operation) for label 64 compilations and we don't need anything
  larger than int32 HashTable capacity anyhow.

ENH: make nearest power-of-two non-branching (previously brute-force)
