I have cleaned up the code in libports a bit and, most significantly, I
have renamed all the public functions from x to _x and created weak
aliases from _x to x. This allows other libraries to wrap or override
functions in libports as is currently attempted by libdiskfs in dead-name.c
(ports_dead_name). However, the current meathod poses two problems:
* libdiskfs has intimate knowledge of libports (i.e. it does
not cleanly wrap the function, but rather, copies the code).
* Link order matters. If libports is linked before libdiskfs,
the ports_dead_name from libports will be used and not the one
from libdiskfs.
I feel that the other utility libraries should also be converted to
use weak aliases.
