Variable size databases, part 2: new --size argument on database
creation; use it for the dbSize field.

(Note that maximum use of this can be obtained on 32-bit platforms only
by compiling with -D_FILE_OFFSET_BITS=64 or similar, otherwise 2^31 is
an upper exclusive limit for off_t and hence for the lseek() call)
