* Add a nooutput function to be used instead of redirecting to /dev/null,
because /dev/null might not exist early in the boot sequence. This
should fix a bug in which the pax autodetection failed when used from
init(8) with a read-only root file system without a /dev/null.
* Move most of the main program into a new makedev_main function,
to allow reuse by MAKEDEV.local.
In MAKEDEV.local:
* Use the new makedev_main function defined in MAKEDEV. This allows
MAKEDEV.local to support all the options understood by MAKEDEV, instead
of only a subset. This should fix a bug in which the setup() function
could try to use pax mode even though that was previously not supported.
In MAKEDEV.local man page:
* Update list of command line options.
* Don't explain all the options, just refer to MAKEDEV(8) man page.
* Remove BUGS section now that all MAKEDEV options are supported
by MAKEDEV.local.
