This adds and enables the PV console used on XEN kernels to
GENERIC/XENHVM kernels in order for it to be used on PVH.

dev/xen/console/console.c:
- Define console_page.
- Move xc_printf debug function from i386 XEN code to generic console
code.
- Rework xc_printf.
- Use xen_initial_domain instead of open-coded checks for Dom0.
- Gate the attach of the PV console to PV(H) guests.
dev/xen/console/xencons_ring.c:
- Allow the PV Xen console to output earlier by directly signaling
the event channel in start_info if the event channel is not yet
initialized.
- Use HYPERVISOR_start_info instead of xen_start_info.
i386/include/xen/xen-os.h:
- Remove prototype for xc_printf since it's now declared in global
xen-os.h
i386/xen/xen_machdep.c:
- Remove previous version of xc_printf.
- Remove definition of console_page (now it's defined in the console
itself).
- Fix some printf formatting errors.
x86/xen/pv.c:
- Add some early boot debug messages using xc_printf.
- Set console_page based on the value passed in start_info.
xen/xen-os.h:
- Declare console_page and add prototype for xc_printf.
(1) Invoke cpp to bring in files via #include (although the old
/include/ stuff is supported still).
(2) bring in files from either vendor tree or freebsd-custom files
when building.
(3) move all dts* files from sys/boot/fdt/dts to
sys/boot/fdt/dts/${MACHINE} as appropriate.
(4) encode all the magic to do the build in sys/tools/fdt/make_dtb.sh
so that the different places in the tree use the exact same logic.
(5) switch back to gpl dtc by default. the bsdl one in the tree has
significant issues not easily addressed by those unfamiliar with
the code.
This is (almost!) enough to actually probe, attach, configure a default
port group and do some basic work. It's also totally hard-coded for
the Qualcomm Atheros DB120 board - it doesn't yet have any of the code
from OpenWRT which parses extra configuration data to know how to program
the switch. The LED stuff is also missing.
But, it's enough to facilitate board, PHY, switch and VLAN bringup,
so I am committing it now.

- netmap pipes, providing bidirectional blocking I/O while moving
100+ Mpps between processes using shared memory channels
(no mistake: over one hundred million. But mind you, i said
*moving* not *processing*);
- kqueue support (BHyVe needs it);
- improved user library. Just the interface name lets you select a NIC,
host port, VALE switch port, netmap pipe, and individual queues.
The upcoming netmap-enabled libpcap will use this feature.
- optional extra buffers associated to netmap ports, for applications
that need to buffer data yet don't want to make copies.
- segmentation offloading for the VALE switch, useful between VMs.
and a number of bug fixes and performance improvements.
My colleagues Giuseppe Lettieri and Vincenzo Maffione did a substantial
amount of work on these features so we owe them a big thanks.
There are some external repositories that can be of interest:
https://code.google.com/p/netmap
our public repository for netmap/VALE code, including
linux versions and other stuff that does not belong here,
such as python bindings.
https://code.google.com/p/netmap-libpcap
a clone of the libpcap repository with netmap support.
With this any libpcap client has access to most netmap
feature with no recompilation. E.g. tcpdump can filter
packets at 10-15 Mpps.
https://code.google.com/p/netmap-ipfw
a userspace version of ipfw+dummynet which uses netmap
to send/receive packets. Speed is up in the 7-10 Mpps
range per core for simple rulesets.
Both netmap-libpcap and netmap-ipfw will be merged upstream at some
point, but while this happens it is useful to have access to them.
And yes, this code will be merged soon. It is infinitely better
than the version currently in 10 and 9.

Move the GPIOBUS lock macros to gpiobusvar.h as they are now shared between
the OFW and the non OFW versions of GPIO bus.
Export gpiobus_print_pins() so it can also be used on the OFW GPIO bus.

Useful for so-called USB tethering.
- Imported code from OpenBSD
- Adapted code to FreeBSD
- Removed some unused functions
- Fixed some buffer encoding and decoding issues
- Optimised data transport path a bit, by sending multiple packets at a time
- Increased receive buffer to 16K

have passed. The firmware now exists in pre-compiled form, no longer

This also fixes the problem introduced with r257777 et al with building

fdtbus in most cases. This brings ARM and MIPS more in line with existing
Open Firmware platforms like sparc64 and powerpc, as well as preventing
double-enumeration of the OF tree on embedded PowerPC (first through nexus,
then through fdtbus).
This change is also designed to simplify resource management on FDT platforms
by letting there exist a platform-defined root bus resource_activate() call
instead of replying on fdtbus to do the right thing through fdt_bs_tag.
The OFW_BUS_MAP_INTR() and OFW_BUS_CONFIG_INTR() kobj methods are also
available to implement for similar purposes.

gets built with the host compiler, not the compiler in obj/... used to build

This includes the following:
- use separate memory regions for VALE ports
- locking fixes
- some simplifications in the NIC-specific routines
- performance improvements for the VALE switch
- some new features in the pkt-gen test program
- documentation updates
There are small API changes that require programs to be recompiled
(NETMAP_API has been bumped so you will detect old binaries at runtime).
In particular:
- struct netmap_slot now is 16 bytes to support an extra pointer,
which may save one data copy when using VALE ports or VMs;
- the struct netmap_if has two extra fields;
