Cleanup block processor flag handling

First, remove the "Don't checksum" flag, fragment blocks also need to
be checksumed and are also subject to deduplication. For sentinel
blocks, instead check if the size is zero.

Second, cleanly seperate the user settable flags from the non-user
settable flags and reject any block that has non-user settable or
unknown flags set.
