The lack of a mapsize option available in mdb_load can make it inconvenient to
load datasets.  This is particularly true when you are using the plaintext
format specified by '-T', since it has no header you could add an appropriate
mapsize to.  My patch resolves this by adding a mapsize option ('-m') which can
be used to manually specify a mapsize of your choosing, overriding both the
default and any value specified in the header of the database you're loading.

The patch also modifies the man page for mdb_load to reflect the new
functionality.  I don't know if the code is good enough for inclusion, but I
figured providing my solution was better than nothing.
