Migrate finger(1) away from <utmp.h>.

Unfortunately it also uses lastlog, which means we must resort to local
extensions of the utmpx-interface. Because the user name and TTY name
are now nul-terminated, there is no need to copy around strings as
often.

Remove T/TCP support, and the -T option which was needed to disable it.

Setting .nofinger will not hide you from root.

Add multiple inclusion guards. Mostly this is for extern.h, which was
included twice by lprint.c, which included both finger.h and extern.h.
finger.h, in turn, includes extern.h. The redundant include of extern.h
was removed from lprint.c, as part of this change, but the include guards
were added anyway out of spite.

ANSIify function definitions.
Add some constness to avoid some warnings.
Remove use register keyword.
Deal with missing/unneeded extern/prototypes.
Some minor type changes/casts to avoid warnings.

Add -g option, which restricts printing of the gecos fields to just the user's
real name.
