leads to compile errors when trying to compile firmware(9) stubs created with
gawk, as multiple #include statements end up on the same line. Replace the
multi-line printc statement that outputs all of the #includes with one printc
per #include. This allows modules compatible with firmware(9) to be cross-built
from a Linux machine without requiring the one true awk to be installed.
I've intentionally done the minimal set of changes necessary to make gawk
produce valid (but not pretty) C code, to reduce the churn and keep fw_stubs.awk
as readable as possible.

- Remove contention on ISR during the crypto operation by using rwlock(9).
- Remove a second lookup of the SA in the callback.
Gain on 6 cores CPU with SHA1/AES128 can be up to 30%.

too much time. This can finish in a scheduler deadlock with ping-pong
between two threads.
One sample of this is:
- device lapic (to have a preemption point on critical_exit())
- options DEVICE_POLLING with HZ>1499 (to have lapic freq = hardclock freq)
- running a cpu intensive task (that does not enter the kernel)
- only one CPU on SMP or no SMP.
As requested by jhb@ 4BSD have received the same type of fix instead of
propagating the flag to the new thread.

bus driver will now remember the size of a BAR obtained during the initial
bus scan and use that size when doing lazy resource allocation rather than
resizing the BAR. The bus driver will now also report unallocated BARs to
userland for display by 'pciconf -lb'. Psuedo-resources that are not BARs
(such as the implicit I/O port resources for master/slave ATA controllers)
will no longer be listed as BARs in 'pciconf -lb'. During resume, BARs are
restored from their new saved state instead of having the raw registers
saved and restored across resume. This also fixes restoring BARs at
unusual loactions if said BAR has been allocated by a driver.
Add a constant for the offset of the ROM BIOS BAR in PCI-PCI bridges and
properly handle ROM BIOS BARs in PCI-PCI bridges. The PCI bus now also
properly handles the lack of a ROM BIOS BAR in a PCI-Cardbus bridge.

- AH does not release the SA like in ESP/IPCOMP when handling EAGAIN
- ipsec_process_done incorrectly release the SA.

I have not properly thought through the commit. After r220031 (linux
compat: improve and fix sendmsg/recvmsg compatibility) the basic
handling for SO_PASSCRED is not sufficient as it breaks recvmsg
functionality for SCM_CREDS messages because now we would need to handle
sockcred data in addition to cmsgcred. And that is not implemented yet.

Introduce the AHB glue for Atheros embedded systems. Right now it's
hard-coded for the AR9130 chip whose support isn't yet in this HAL;
it'll be added in a subsequent commit.
Kernel configuration files now need both 'ath' and 'ath_pci' devices; both
modules need to be loaded for the ath device to work.
on the set of rules it maintains and the current resource usage. It also
privides userland API to manage that ruleset.

to the maximum allowed window. Growing the window too large would cause
an underflow in the calculations in tcp_output() to decide if a window
update should be sent which would prevent the persist timer from being
started if data was pending and the other end of the connection advertised
an initial window size of 0.
