So far the udp_tun_func_t had been (ab)using inp_ppcb for udp in kernel
tunneling callbacks. Move that into the udpcb and add a field for flags
there to be used by upcoming changes instead of sticking udp only flags
into in_pcb flags2.
Bump __FreeBSD_version for ports to detect it and because of vnet* struct
size changes.

This also permits tuning of the option per virtual network stack, as
well as separately per inet, inet6.

Cryptodev uses UIO structure do get data from userspace and pass it to
cryptographic engines. Initially UIO size is equal to size of data passed to
engine, but if UIO is prepared for hash calculation an additional small space
is created to hold result of operation.
While creating space for the result, UIO I/O vector size is correctly
extended, but uio_resid field in UIO structure is not modified.
As bus_dma code uses uio_resid field to determine size of UIO DMA mapping,
resulting mapping hasn't correct size. This leads to a crash if all the
following conditions are met:
1. Hardware cryptographic accelerator writes result of hash operation
using DMA.
2. Size of input data is less or equal than (n * PAGE_SIZE),
3. Size of input data plus size of hash result is grather than
(n * PAGE_SIZE, where n is the same as in point 2.
This patch fixes this problem by adding size of the extenstion to uio_resid
field in UIO structure.

In general, this change should reduce the number of traps that occur for
the purpose of setting the modified bit. More specifically, this change
should prevent traps while holding locks in a sysctl handler. See
kern/kern_sysctl.c revisions 1.168 and 1.195 (svn r192160) for further
details.

the code will build when "options KGSSAPI" is specified
without requiring the proposed changes that add host based
initiator principal support. It will not handle the case where
the client uses a host based initiator principal until those
changes are committed. The code that uses those changes is
#ifdef'd notyet until the krpc rpcsec_changes are committed.

because struct vnet_net holds the rt_tables[][] for MRT and array size
is compile time dependent. If you had ROUTETABLES set to >1 after
r192011 V_loif was pointing into nonsense leading to strange results
or even panics for some people.

for reassigning ifnets from one vnet to another.
if_vmove() works by calling a restricted subset of actions normally
executed by if_detach() on an ifnet in the current vnet, and then
switches to the target vnet and executes an appropriate subset of
if_attach() actions there.
if_attach() and if_detach() have become wrapper functions around
if_attach_internal() and if_detach_internal(), where the later
variants have an additional argument, a flag indicating whether a
full attach or detach sequence is to be executed, or only a
restricted subset suitable for moving an ifnet from one vnet to
another. Hence, if_vmove() will not call if_detach() and if_attach()
directly, but will call the if_detach_internal() and
if_attach_internal() variants instead, with the vmove flag set.
While here, staticize ifnet_setbyindex() since it is not referenced
from outside of sys/net/if.c.
Also rename ifccnt field in struct vimage to ifcnt, and do some minor
whitespace garbage collection where appropriate.
This change should have no functional impact on nooptions VIMAGE kernel
builds.

Some hardware easily comes out of sync with regard to whether the current or

issued before receiving the SETUP packet. After this patch the stall command
