[svn-r16847] Description:

Bring r16846 from revise_chunks branch back to trunk: Fix broken (for how long?) H5_ASSIGN_OVERFLOW macro to actually detect overflows during assignments, along with several errors it [now] detected. Cleaned up a fix minor warnings and/or pieces of code also. Tested on: FreeBSD/32 6.3 (duty) in debug mode (h5committest not needed - multi-platform test performed on branch)
