c97fcdba57 Add VOP_ACCESSX, which can be used to query for newly added V*
permissions, such as VWRITE_ACL.  For a filsystems that don't
implement it, there is a default implementation, which works
as a wrapper around VOP_ACCESS.

a16ccdcead Adds missing sysctl to manage the vtag_time_wait time. This will
even allow disabling time-wait all together if you set the value
to 0 (not advisable actually). The default remains the same
i.e. 60 seconds.

6911f596a1 rm, find -delete: fix removing symlinks with uchg/uappnd set.
Formerly, this tried to clear the flags on the symlink's target
instead of the symlink itself.

As before, this only happens for root or for the unlink(1) variant of rm.

946a48449b Make ipi_cpu() function as intended.
IPI's in Xen are implemented through hypervisor event channels.
The MP code creates a pair of IRQs for each base IPI per CPU
(one for IPI function dispatch calls, one for IPI bitmap dispatch calls.)
Using PCPU_GET() was returning the IRQ of the IPI handler for the
current CPU; thus calls to ipi_cpu() were sending itself a message.
Instead, looking up the IPI in the target CPU ipi-to-irq map is needed.

Note: This doesn't fix Xen SMP (far from it!) but it at least
sends IPI's to the right places. Next - sending IPIs..

76ca6f88da Place hostnames and similar information fully under the prison system.
The system hostname is now stored in prison0, and the global variable
"hostname" has been removed, as has the hostname_mtx mutex.  Jails may
have their own host information, or they may inherit it from the
parent/system.  The proper way to read the hostname is via
getcredhostname(), which will copy either the hostname associated with
the passed cred, or the system hostname if you pass NULL.  The system
hostname can still be accessed directly (and without locking) at
prison0.pr_host, but that should be avoided where possible.

The "similar information" referred to is domainname, hostid, and
hostuuid, which have also become prison parameters and had their
associated global variables removed.

fd27593538 Fix the Xen TOD update when the hypervisor wall clock is nudged.
The "wall clock" in the current code is actually the hypervisor start time.
The time of day is the "start time" plus the hypervisor "uptime".

Large enough bumps in the dom0 clock lead to a hypervisor "bump" which is
implemented as a bump in the start time, not the uptime. The clock.c routines
were reading in the hypervisor start time and then using this as the TOD.
This meant that any hypervisor time bump would cause the FreeBSD DomU to
set its TOD to the hypervisor start time, rather than the actual TOD.

This fix is a bit hacky and some reshuffling should be done later on
to clarify what is going on. I've left the wall clock code alone.
(The code which updates shadow_tv and shadow_tv_version.)
A new routine adds the uptime to the shadow_tv, which is then used to
update the TOD.

I've included some debugging so it is obvious when the clock is nudged.

1a109c1cb0 Make the rmlock(9) interface a bit more like the rwlock(9) interface:
- Add rm_init_flags() and accept extended options only for that variation.
- Add a flags space specifically for rm_init_flags(), rather than borrowing
  the lock_init() flag space.
- Define flag RM_RECURSE to use instead of LO_RECURSABLE.
- Define flag RM_NOWITNESS to allow an rmlock to be exempt from WITNESS
  checking; this wasn't possible previously as rm_init() always passed
  LO_WITNESS when initializing an rmlock's struct lock.
- Add RM_SYSINIT_FLAGS().
- Rename embedded mutex in rmlocks to make it more obvious what it is.
- Update consumers.
- Update man page.

32bf7cdf5a Let vfs_lookup() return ENOTDIR if the path has a trailing slash and
the last component is a symlink to something that isn't a directory.

We introduce a new namei flag, TRAILINGSLASH, which is set by lookup()
if the last component is followed by a slash.  The trailing slash is
then stripped, as before.  If the final component is a symlink,
lookup() will return to namei(), which will expand the symlink and
call lookup() with the new path.  When all symlinks have been
resolved, lookup() checks if the TRAILINGSLASH flag is set, and if it
is, and the vnode it ended up with is not a directory, it returns
ENOTDIR.

c5e30cc02b Last minute TTY API change: remove mutex argument from tty_alloc().
I don't want people to override the mutex when allocating a TTY. It has
to be there, to keep drivers like syscons happy. So I'm creating a
tty_alloc_mutex() which can be used in those cases. tty_alloc_mutex()
should eventually be removed.

The advantage of this approach, is that we can just remove a function,
without breaking the regular API in the future.
