Update nfsrv_getsocksndseq() for changes in TCP internals since FreeBSD 6.x:
- so_pcb is now guaranteed to be non-NULL and valid if a valid socket
reference is held.
- Need to check INP_TIMEWAIT and INP_DROPPED before assuming inp_ppcb is a
tcpcb, as it might be a tcptw or NULL otherwise.
- tp can never be NULL by the end of the function, so only check
TCPS_ESTABLISHED before extracting tcpcb fields.
The NFS server arguably incorporates too many assumptions about TCP
internals, but fixing that is left for another day.

Remove unnecessary locking of divcbinfo lock from div_output(): this has

Add uep(4), driver for USB onscreen touch panel from eGalax.
The driver is stub. It just creates device entry and feeds
reassembled packets from hardware into it.
If in future we would port wsmouse(4) from NetBSD, or make
sysmouse(4) to support absolute motion events, then the driver
can be extended to act as system mouse. Meanwhile, it just
presents a /dev/uep0, that can be utilized by X driver, that
I am going to commit to ports tree soon.
The name for the driver is chosen to be the same as in NetBSD,
however, due to different USB stacks this driver isn't a port.
The driver is supported by ports/x11-drivers/xf86-input-egalax.

Synchronize Coda kernel module definitions in our coda.h to Coda 6's
coda.h:
- CodaFid typdef -> struct CodaFid throughout.
- Use unsigned int instead of unsigned long for venus_dirent and other
cosmetic fixes.
- Introduce cuid_t and cgid_t and use instead of uid_t and gid_t in RPCs.
- Synchronize comments and macros.
- Use u_int32_t instead of unsigned long for coda_out_hdr.
With these changes, a 64-bit Coda kernel module now works with
coda6_client, whereas previous userspace and kernel versions of RPCs
differed sufficiently to prevent using the file system. This has been
verified only with casual testing, but /coda is now usable for at least
basic operations on amd64.

When close() is called on a connected socket pair, SO_ISCONNECTED might be
set but be cleared before the call to sodisconnect(). In this case,
ENOTCONN is returned: suppress this error rather than returning it to
userspace so that close() doesn't report an error improperly.

ifconfig(8) expects interface fooX to be supported by the module if_foo,
and will try to load it if it's not present. To better meet these
expectations, change the module name for the loopback interface from
'loop' to 'if_lo'. The loopback interface is always compiled into the
base kernel, so there are no resulting changes in kld files, etc.

Add a new build option, MAN_UTILS. This option lets you control building
utilities and related support files for manual pages, which were previously
controlled by MAN. For POLA, the default depends on MAN, i.e., WITHOUT_MAN
implies WITHOUT_MAN_UTILS and WITH_MAN implies WITH_MAN_UTILS.
Note this patch implicitly fixes a documentation bug of src.conf(5), which
says WITHOUT_MAN may be used to not build manual pages while it was also
disabling some utilities for manual pages.

Use the iflladdr_event event to keep the mac address on the vap in sync with
the parent wirless interface. If the user passed in a mac address or it was
autogenerated then flag this to avoid trashing it on update.
This will fix wlan+lagg in a post vap world.
Declare a new EVENTHANDLER called iflladdr_event which signals that the L2
address on an interface has changed. This lets stacked interfaces such as
vlan(4) detect that their lower interface has changed and adjust things in
order to keep working. Previously this situation broke at least vlan(4) and
lagg(4) configurations.
The EVENTHANDLER_INVOKE call was not placed within if_setlladdr() due to the
risk of a loop.
