Update libarchive to 3.0.3
Some of new features:
- New readers: RAR, LHA/LZH, CAB reader, 7-Zip
- New writers: ISO9660, XAR
- Improvements to many formats, especially including ISO9660 and Zip
- Stackable write filters to write, e.g., tar.gz.uu in a single pass
- Exploit seekable input; new "seekable" Zip reader can exploit the Zip
Central Directory when it's available; the old "streamable" Zip reader
is still fully supported for cases where seeking is not possible.

When detaching an unix domain socket, uipc_detach() checks
unp->unp_vnode pointer to detect if there is a vnode associated with
(binded to) this socket and does necessary cleanup if there is.
The issue is that after forced unmount this check may be too late as
the unp_vnode is reclaimed and the reference is stale.
To fix this provide a helper function that is called on a socket vnode
reclamation to do necessary cleanup.

Use correct Config registers for RTL8139 family. Unlike RTL8168 and
RTL810x family , RTL8139 has different register map for Config
registers.
While here, follow the lead of re(4) in WOL configuration.
- Disable WOL_UCAST and WOL_MCAST capabilities by default.
- Config5 register write does not need to unlock EEPROM access
on RTL8139 family but unlocking EEPROM access does not affect
its operation and make it consistent with re(4).

In revision 231989, we pass a 16-bit clock ID into kernel, however
according to POSIX document, the clock ID may be dynamically allocated,
it unlikely will be in 64K forever. To make it future compatible, we
pack all timeout information into a new structure called _umtx_time, and
use fourth argument as a size indication, a zero means it is old code
using timespec as timeout value, but the new structure also includes flags
and a clock ID, so the size argument is different than before, and it is
non-zero. With this change, it is possible that a thread can sleep
on any supported clock, though current kernel code does not have such a
POSIX clock driver system.

Forced commit to denote that the commit message of r231621 should have read:
- As it turns out, MSI-X is broken for at least LSI SAS1068E when passed
through by VMware so blacklist their PCI-PCI bridge for MSI/MSI-X here.
Note that besides currently there not being a quirk type that disables
MSI-X only and there's no evidence that MSI doesn't work with the VMware
pass-through, it's really questionable whether MSI generally works in
that setup as VMware only mention three know working devices [1, p. 4].
Also not that this quirk entry currently doesn't affect the devices
emulated by VMware in any way as these don't claim support MSI/MSI-X to
begin with. [2]

Account the writeable shared mappings backed by file in the vnode
v_writecount. Keep the amount of the virtual address space used by
the mappings in the new vm_object un_pager.vnp.writemappings
counter. The vnode v_writecount is incremented when writemappings gets
non-zero value, and decremented when writemappings is returned to
zero.
Writeable shared vnode-backed mappings are accounted for in vm_mmap(),
and vm_map_insert() is instructed to set MAP_ENTRY_VN_WRITECNT flag on
the created map entry. During deferred map entry deallocation,
vm_map_process_deferred() checks for MAP_ENTRY_VN_WRITECOUNT and
decrements writemappings for the vm object.
Now, the writeable mount cannot be demoted to read-only while
writeable shared mappings of the vnodes from the mount point

hrs@ reported a panic to freebsd-stable@ under the subject line
"panic in 8.3-PRERELEASE" on Feb. 22, 2012. This panic was caused
by use of a mix of tsleep() and msleep() calls on the same event
in the new NFS server DRC code. It did "mtx_unlock(); tsleep();"
in two places, which kib@ noted introduced a slight risk that the
wakeup() would occur before the tsleep(), resulting in a 10sec
delay before waking up. This patch fixes the problem by replacing
"mtx_unlock(); tsleep();" with mtx_sleep(..PDROP..). It also
changes a nfsmsleep() call to mtx_sleep() so that the code uses
mtx_sleep() consistently within the file.
