*_mountfs() (if the filesystem mounts from a device) needs devvp to be
locked, so lock it.
Approved by: re (scottl)
Don't unbusy the devfs mount in vfs_mountroot_try() as it gets accessed
and unbusied in devfs_fixup(), which assumes that the devfs mount is
still locked.

Take a first cut at cleaning up ifnet removal and multicast socket
panics, which occur when stale ifnet pointers are left in struct
moptions hung off of inpcbs:
- Add in_ifdetach(), which matches in6_ifdetach(), and allows the
protocol to perform early tear-down on the interface early in
if_detach().
- Annotate that if_detach() needs careful consideration.
- Remove calls to in_pcbpurgeif0() in the handling of SIOCDIFADDR --
this is not the place to detect interface removal! This also
removes what is basically a nasty (and now unnecessary) hack.
- Invoke in_pcbpurgeif0() from in_ifdetach(), in both raw and UDP
IPv4 sockets.
It is now possible to run the msocket_ifnet_remove regression test
using HEAD without panicking.

- Remove sis_unit and use device_printf() and if_printf() instead.
- Use callout_init_mtx() for the callout.
- Remove spls.
- Fix locking for ifmedia to happen in the ifmedia handlers rather than in
sis_ioctl().

rpcclnt.c:1.14 from HEAD to RELENG_6:
Acquire Giant in uprintf() and tprintf() due to the non-MPSAFEty of
the tty code invoked from these functions. In two cases, during
timeout handling in NFS-related RPC client code, acquire Giant in
the caller before other mutexes the caller might hold, in order to
avoid lock order reversals with Giant (a recursive acquire is not
a reversal as it won't ever wait).
Correct age-old comments about uprintf()/tprintf() sleeping: they
will never sleep.

- Print space character in show_stat(). Remove a lot of priuntf(" ").
- Utilize show_stat() in sidewaysintpr() loop. This makes periodic
statistics to honor -h flag.

Lock the read socket receive buffer when frobbing the sb_state flag on

For reasons of consistency (and necessity), assert an exclusive vnode
lock on the fifo vnode in fifo_open(): we rely on the vnode lock to
serialize access to v_fifoinfo.

Add three new read-only socket options, which allow regression tests
and other applications to query the state of the stack regarding the
accept queue on a listen socket:
SO_LISTENQLIMIT Return the value of so_qlimit (socket backlog)
SO_LISTENQLEN Return the value of so_qlen (complete sockets)
SO_LISTENINCQLEN Return the value of so_incqlen (incomplete sockets)
Minor white space tweaks to existing socket options to make them
consistent.

the RDONLY option, so subsequent call of UFS_TRUNCATE (ffs_truncate)
would not panic the system. This fixes a panic that can happen
when mounting a corrputed filesystem read-only, and reading data
from it.

Split the do_powerstaes knob into do_power_resume and do_power_nodriver.
Go ahead and enable power state management for suspend/resume, but leave
the nodriver powerdown off by default. The MFC that changed do_power_state
default to 0 broke some resume on some laptops.

Several fixes to rt_setgate(), that fix problems with route changing:
- Rearrange code so that in a case of failure the affected
route is not changed. Otherwise, a bogus rtentry will be
left and later rt_check() can recurse on its lock. [1]
- Remove comment about protocol cloning.
- Fix two places where rtentry mutex was recursed on, because
accessed via two different pointers, that were actually pointing
to the same rtentry in some cases. [1]
- Return EADDRINUSE instead of bogus EDQUOT, in case when gateway
uses the same route. [2]

Pass 'curthread' into VFS_STATFS() from acctwatch(), rather than passing
NULL. The NFS client expects that a thread will always be present for a
VOP so that it can check for signal conditions, and will dereference a
NULL pointer if one isn't present.
