with individual devices for each type of sound card:
opl, sb, sbxvi, sbmidi, pas, mpu, gus, gusxvi, gusmax, mss, uart
EXCLUDE_* options are no longer required to be included in the config file.
They are automatically determined by local.h depending on the devices
included.
Move #includes in local.h to os.h so files are included in the proper
order to avoid warnings.
soundcard.c now has additional code to reflect the device driver
routines needed.
Define new EXCLUDE_SB16MIDI for use in sb16_midi.c and dev_table.h.
#ifndef EXCLUDE_SEQUENCER or EXCLUDE_AUDIO have been added to
soundcard.c and sound_switch.c where appropriate.
Probe outputs changed to reflect new device names.
Readme.freebsd not needed. Update sound.doc with new config instructions.

and M_IPFW for firewall chans memory on the same opportunity,
theese types of memory are unique enough to have own identifiers and
besides vmstat looks much more useful and right for those now
allow Q_SYNC regardless of "target" uid, we allow it with -1;
fix bug that caused all ops to refer to user quotas, not group.

To use this: recompile src/gnu/usr.bin/cc, compile your kernel. The
files you want to profile should be compiled with '-a -g'. "strip -x"
the kernel and run. You don't need to profile all files in the kernel.
My next commit is the program to extract the data from the running kernel.
1. We always keep one 16th of the vnodes on the freelist, so that the
namecache doesn't get trashed. It used to be that it wasn't a problem, but
the only vnodes getting released these days are directories and things which
Clean up and improve the namecache.

namecache doesn't get trashed. It used to be that it wasn't a problem, but
the only vnodes getting released these days are directories and things which
gets forced out of the VM/cache. The latter is not numerous enough to keep
the pool of vnodes needed for the namecache sufficiently big.
2. Purge invalid entries in the namecache as soon as we notice them. This
avoids a stale entry pushing out a valid entry on the LRU list.
3. Speed up the lookup in the namecache by avoid a special case branch.
4. Make the cache purge routines do the thing they're supposed to, and in
a decently efficient manner.
5. Make the size of the namecache follow the number of vnodes, so that we
can always point to all the vnodes we have in core.
6. Readability has gone way up.
7. Added a "options NCH_STATISTICS" feature that will gather more
detailed statistics on the performance of the namecache.

object has fallen off the end of the cached list - this is likely the
last reference to the vnode and it should be reused before non file
vnodes that are already on the free list (VDIR mostly).
