This patch should fix handling of byte range locks locally
on the server for the experimental nfs server. When enabled
by setting vfs.newnfs.locallocks_enable to non-zero, the
experimental nfs server will now acquire byte range locks
on the file on behalf of NFSv4 clients, such that lock
conflicts between the NFSv4 clients and processes running
locally on the server, will be recognized and handled correctly.
Add preliminary support for 8168E/8111E PCIe controller.
While I'm here simplify device description string.

Partial revert r204545.
Just relying on status LE ownership of status block seems to cause
poor performance. Always read current status index register first
and then check status ownership as we had before. Accessing status
index register seems to trigger immediate status update if
controller have pending status updates.

Change where we nap so that if pwait(1) returns but kill -0 still sees
a zombie we don't print an endless string of the same pid number until
the zombie exits.
While I'm here, local'ize the variables that this function uses.
Two fixes:
(1) We don't need a custom install_kernel. We can install without
symbols by adding INSTALL_NODEBUG (which likely should be
WITHOUT_KERNEL_SYMBOLS_FILE, or something shorter) to CONF_INSTALL
(2) for make buildenv stage, use NANO_MAKE_CONF_BUILD rather than the
non-existant NANO_MAKE_CONF.

Stop hard coding i386 as the arch for the build. Instead, default to the
processor we're running on. Also, supply amd64 version of create_diskimage
that's the same as i386's.
# didn't fix the confusion between using the processor for this and using
# the machine (which would be more appropriate). NANO_ARCH smashes the two
# together right now.

When you have multiple addresses on the same network on different
interfaces (such as when you are part of a carp pool), and you run
rpcbind -h to restrict which interfaces have rpc services, rpcbind can
none-the-less return addresses that aren't in the -h list. This patch
enforces the rule that when you specify -h on the command line, then
services returned from rpcbind must be to one of the addresses listed
in -h, or be a loopback address (since localhost is implicit when
running -h).
The root cause of this is the assumption in addrmerge that there can
be only one interface that matches a given network IP address. This
turns out not to be the case. To retain historical behavior, I didn't
try to fix the routine to prefer the address that the request came
into, since I didn't know the side effects that might cause in the
normal case. My quick analysis suggests that it wouldn't be a
problem, but since this code is tricky I opted for the more
conservative patch of only restricting the reply when -h is in effect.
Hence, this change will have no effect when you are running rpcbind
without -h.

Escape characters unsafe for XML output in GEOM class, instance and
provider names.
- Characters in range 0x01-0x1f except '\t', '\n', and '\r' are replaced
with '?'. Those characters are disallowed in XML.
- '&', '<', '>', '\'', '"' and characters in range 0x7f-0xff are
replaced with XML numeric character reference.
If the kern.geom.confxml sysctl provides invalid XML, libgeom
geom_xml2tree() fails and utilities using it do not work. Unsafe
characters are common in msdosfs and cd9660 labels.

Supply default implementation of VOP_RENAME() that does neccessary
unlocks and unreferences for argument vnodes, as expected by
kern_renameat(9), and returns EOPNOTSUPP. This fixes locks and
reference leaks when rename is attempted on fs that does not
implement rename.
Add function vop_rename_fail(9) that performs needed cleanup for locks
and references of the VOP_RENAME(9) arguments. Use vop_rename_fail()
in deadfs_rename().
vm_reserv_alloc_page() should never be called on an OBJT_SG object, just
as it is never called on an OBJT_DEVICE object. (This change should have
been included in r195840.)
Patch the experimental NFS server in a manner analagous to r205661
for the regular NFS server, to ensure that ESTALE is
returned to the client for all errors returned by VFS_FHTOVP().
Patch the regular NFS server so that it returns ESTALE to the client
for all errors returned by VFS_FHTOVP(). This is required to ensure
that EIO doesn't get returned to the client when ZFS is used as the
server file system.
Remove the check for IFF_DRV_OACTIVE right before adding a port into lagg

seem to be useful for our code.

For unhandled actions in xpt_action_default, remember to call
xpt_done for queued requests. This solves the problem of
indefinite hangs for unspecified transports when XPT_SCAN_BUS
is called.
A few minor cosmetics elsewhere.
Move SysV IPC freebsd32 compat shims from freebsd32_misc.c to corresponding
sysv_{msg,sem,shm}.c files.
Mark SysV IPC freebsd32 syscalls as NOSTD and add required
SYSCALL_INIT_HELPER/SYSCALL32_INIT_HELPERs to provide auto
register/unregister on module load.
This makes COMPAT_FREEBSD32 functional with SysV IPC compiled and loaded
as modules.
Introduce SYSCALL_INIT_HELPER and SYSCALL32_INIT_HELPER macros and
neccessary support functions to allow registering dynamically loaded
syscalls from the MOD_LOAD handlers. Helpers handle registration
failures semi-automatically.
For SYSCALL_MODULE_HELPER, use "sys/<syscallname>" module name.
For SYSCALL32_MODULE_HELPER, use "sys32/<syscallname>" module name.
This avoids modules name conflict when compat32 syscall does not
need shims.
