set the makefile to build the bootloader without the DB_MONITOR stuff by
default, as it is primarily for debugging. Reduces bootloader size by
about 8k.
SIOCSIFFLAGS: it compares the new flags with the old flags and avoids
reset if there are only certain changes. This was done to fix PR 29126.
It does not take into account, though, that there is other state which
can change and SIOCSIFFLAGS is called to inform about it. Namely,
if_capenable, ec_capenable and ec_nvlans. For all three, the _init
method must program the hardware specially. Not doing it resulted in:
- VLAN frames getting truncated
- hw checksumming not working
- outgoing VLAN frames not being tagged when they should
- incoming VLAN frames being treated as untagged.
Fix by keeping all the old state in the softc and initializing the
hardware if any of it changes.
Tested on gsip. Also tested by Nino Dehne and Martin J. Laubach
on sip, thanks.
Fixes PRs 32900 and 33216.

- avoid double slashes when displaying man pages (got tired
of '/usr/share/man//cat1/man.0').
- got rid of __P() while working on it.
- incorporate some of my old notes explaining how manpath works into the
comments of the code itself.
- renamed some of the vars so that the code is consistent throughout
(and hopefully clearer and easier to understand)
- fixed relative man paths for multiple man pages (man did a chdir()
on the first man page it had to format --- this broke any remaining
relative path man pages left to process). save old directory and
fchdir() back to it after formatting.
- improved doc on "man -h" which does more than just whatis(1) [e.g.
"man -h fopen" prints the required include files and the prototypes
rather than just the one-liner you get with whatis(1)]
- manconf.c now fills in the "len" length field in the TAG/ENTRY
structures (man now uses len).
revise man.conf file reading stuff to return error on failure in
addentry/gettag (fka getlist) rather than just err()ing out. this
allows man(1) to call cleanup and delete its tmp files rather than
just leave them floating. revise other apps using this code
(makewhatis, apropos, catman, whatis) to expect this. also remove
__P on updated files.
