[svn-r19328] Description:

    Add some extra range checking for invalid chunk sizes.

    Tweak default chunk sizes to be zero, so that it's more likely that
application developers will be forced to set them correctly.

    Add a few tests to verify these checks.

Tested on:
    Mac OS X/32 10.6.4 (amazon) w/debug & production
    (too minor to require h5committest)
