later. This allows tunefs -p on mounted filesystems.
Side-effects:
Use K&R prototypes.
Use definitions from fcntl.h for the flags argument to open(2).
There are cosmetic differences between this and the submitted patch.

parameters are. You can use dumpfs, but that's not obvious which settings
are tuneable, and is far from clear to the non-guru (it's like using a
hexdump of a tar archive to get a table-of-contents).
There is also an undocumented option in the man page that can be dangerous.
Suppose your disk driver decides to scramble all writes while you tell
tunefs to update all backup superblocks.
This suggested change adds a '-p' (print) switch to bring it in
line with some SVR4 systems.
