Fragment number field (part of i_seq) is used for AAD calculation;
as a result, without this patch every driver without h/w crypto support
need to clear it before ieee80211_crypto_encap().
Also fixes rtwn(4) A-MPDU Tx with dev.rtwn.%d.hwcrypto tunable
set to 0 (h/w crypto is disabled).
Tested with:
* Intel 6205, STA mode.
* RTL8188EU, STA mode.

- Refactor kld loading/unloading logic:
-- Use a loop instead of an unrolled one.
-- Check for the module being loaded before trying to load it, to reduce
noise when loading modules that are already loaded.
-- Don't mute stderr from kldload -- it could be potentially useful to
the tester.
-- In the event that the test script was terminated early, it would leave
the modules still attached to the system (which is undesirable).
Always unload the modules at test end with EXIT/SIGINT/SIGTERM so the
system is returned to its former operating state as best possible.
Unload the modules in reverse order, in part for consistency and/or
dependency reasons.

The problem is that when the parameter 'pat' is null, the function locally
allocates a NULL string but never frees it.
Instead of tracking the local alloc, it is noted that the while(*pat) never
enters when there is a local alloc.
So instead of doing the local alloc, check that 'pat' is null before the
while(*pat) loop.

It is simply a contigous virtual memory pointer and number of pages.
There is no need to build a linked list here. Just increment pointer
and decrement counter. The only functional difference to old allocator
is that before we gave pages from topmost and down to lowest, and now
we give them in normal ascending order.
While here remove padalign from a mutex that is unused at runtime.

polling contexts in the LinuxKPI.
After the kqueue() support was added to the LinuxKPI in r319409 the
Linux poll file operation will be used outside the system file polling
callback function, which can cause a NULL-pointer panic inside
selrecord() because curthread->td_sel is set to NULL. This patch moves
the selrecord() call away from poll_wait() and to the system file poll
callback function in the LinuxKPI, which essentially wraps the Linux
one. This is similar to what the cuse(3) module is currently doing.
Refer to sys/fs/cuse/*.[ch] for more details.

devices. The implementation allows read and write filters to be
created and piggybacks on the poll() file operation to determine when
a filter should trigger. The piggyback mechanism is simply to check
for the EWOULDBLOCK or EAGAIN return code from read(), write() or
ioctl() system calls and then update the kqueue() polling state bits.
The implementation is similar to the one found in the cuse(3) module.

Background:
The Linux VM open operation is called when a new VMA is
created on top of the current VMA. This is done through either mremap
flow or split_vma, usually due to mlock, madvise, munmap and so
on. This is currently not supported by the LinuxKPI.

- Set the "_file" member of "struct linux_file" during open. This
