09bae951cd Better fix for the deletion of parents of cloned routes problem, 
superseding the `nextchild' hack.  This also provides a way
forward to fix RTM_CHANGE and RTM_ADD as well.

d590bce33d The discard, tunnel, SLIP, and PPP network interface pseudo-devices 
are now dynamically loadable.  It doesn't make sense to do the same
for the loopback.

1a3906ad11 Support for pseudo-device LKMs. Note that this is restricted to only 
one pseudo per module (a restriction which will eventually be lifted) and
isthus not in its final form.

2a30dae2a5 This should be splimp() rather than splnet() since ifaddrs might go away 
as a result of link-layer processing.

fd40ec89df Fix race conditions involved in setting IP multicast options. This should 
fix Dennis Fortin's problem for good, if I've got it figured out right.

(The problem was that a `struct ifaddr' could get deleted out from under
the current requester, thus leaving him with an invalid interface pointer
and causing even more bogus accesses.)

390bfe9b40 Incorporated 4.4-lite vnode_pager_uncache() and vnode_pager_umount() 
routines (and merged local changes). The changed vnode_pager_uncache
gets rids of the bogosity that you can call the routine without
having the vnode locked. The changed vnode_pager_umount properly locks
the vnode before calling vnode_pager_uncache.

a62ef20881 Moved call to vnode_pager_uncache in rename() to before the VOP_RENAME. 
It was previously after the VOP_RENAME and the reference and lock on
the vnode had already been lost, allowing interesting internel
inconsistencies. This is one of the two reasons why freefall was crashing
every hour or two (the other being nullfs bugs).
Don't call vnode_pager_uncache in revoke(). revoke() is only allowed on
VCHR and VBLK vnodes.

e38e0cc286 Don't sync the inode date changes of character special devices 
during the FS sync. The system would appear to hang momentarily
if there was a large backlog of I/O. This is because the vnode
remains locked during the output - preventing normal character
I/O. The problem was exacerbated by the FFS contiguous block
allocation fixes and a semi-broken disksort(). The inode/date
will still be synced during a normal FS dismount and whenever
the inode is changed for other reasons.

107fa9cbb1 Increase the DELAY used in ahc_poll. This is only used during intial 
probe of the device and shouldn't affect normal operation.  It seems that
some version of the aic7870 are extreamly slow in clearing their interrupt
register so the added delay is required to ensure we don't poll a stale
interrupt value.

Clean up debugging printfs and stuff superflous output into #ifdef AHC_DEBUG.

Ensure that sdtrpending and wdtrpending are cleared in all cases after
we recieve an SDTR or WDTR message.

With this commit, the 294x should work or at least be much closer to
working properly.

8e37e9f479 Add four more filesystem flags: 
VFCF_NETWORK (this FS goes over the net)
	VFCF_READONLY (read-write mounts do not make any sense)
	VFCF_SYNTHETIC (data in this FS is not real)
	VFCF_LOOPBACK (this FS aliases something else)

cd9660 is readonly; nullfs, umapfs, and union are loopback; NFS is netowkr;
procfs, kernfs, and fdesc are synthetic.
