This follows NTB subsystem modularization in Linux, tuning it to FreeBSD
native NewBus interfaces. This change allows to support different types
of hardware with different drivers, support multiple NTB instances in a
system, ntb_transport module use for needs other then if_ntb, etc.

lang/gcc{48,49,5} lacks -fformat-extensions support (causing build errors, which
is what prompted r302403 to be committed). devel/amd64-gcc on the other hand
(which is used by Jenkins), has the support.
This fixes the Jenkins failure emails due to excessive warnings being produced
with "make buildkernel".

Ports versions of gcc do not have -fformat-extensions support.
This unbreaks compiling the kernel/modules with non-base gcc (4.8,

default. At least initially, the feature to support multiple TCP stacks is
aimed at supporting advanced use cases and TCP development, but it is not
necessarily aimed at a wide audience. Therefore, there is no need to build
and install the extra TCP stacks by default. Instead, the people who are
using or developing this functionality can add the extra option to build/
install the extra TCP stacks.
However, we do want to build the extra TCP stacks as part of test builds
(e.g. LINT or tinderbox) to ensure that developers who are testing their
changes will know that their changes do not break the additional TCP
stack modules.
After this change, a user will need to add WITH_EXTRA_TCP_STACKS=1 to
make.conf or the kernel config in order to build the extra TCP modules.

Now that bhnd(4) provides feature parity with the previous siba/mips
implementation, we can switch sentry5 over and begin lifting common
support code out for use across bhnd(4) embedded targets.
Changes:
- Fixed enumeration of siba(4) per-core address maps, required for
discovery of memory mapped chipc flash region on siba(4) devices.
- Simplified bhnd kernel configuration (dropped 'bhndbus' option).
- Replaced files.broadcom's direct file references with their
corresponding standard kernel options.
- Lifted out common bcma/siba nexus support, inheriting from the new
generic bhnd_nexus driver.
- Dropped now-unused sentry5 siba code.
- Re-integrated BCM into the universe build now that it actually compiles.

This breaks cross-building with WITH_META_MODE since it will rebuild
'build-tools' during the 'everything' phase.
A more proper fix is coming to bmake to implicitly require .META unless
.NOMETA (and other restrictions) are in place.
framework has significantly changed the driver has moved to a new file.
While it shares some code with the existing driver this has been modified
to work better with the intrng framework.
This has been tested on the ThunderX servers in the netperf cluster and has
been used to boot them for other testing, including DTrace and hwpmc.
With this we can use intrng on all supported arm64 platforms I was able to
test on. It is expected we will move to intrng soon, and disable the old
arm64 interrupt framework.

This is the initial framework to call into the MCI HAL routines and drive
the basic state engine.
The MCI bluetooth coex model uses a command channel between wlan and
bluetooth, rather than a 2-wire or 3-wire signaling protocol to control things.
This means the wlan and bluetooth chip exchange a lot more information and
signaling, even at the per-packet level. The NICs in question can share
the input LNA and output PA on the die, so they absolutely can't stomp
on each other in a silly fashion. It also allows for the bluetooth side
to signal when profiles come and go, so the driver can take appropriate
control. There's also the possibility of dynamic bluetooth/wlan duty cycle
control which I haven't yet really played with.
It configures things up with a static "wlan wins everything" coexistence,
configures up the available 2GHz channel map for bluetooth, sets a static
duty cycle for bluetooth/wifi traffic priority and drives the basics needed to
keep the MCI HAL code happy.
It doesn't do any actual coexistence except to default to "wlan wins everything",
which at least demonstrates that things do indeed work. Bluetooth inquiry frames
still trump wifi (including beacons), so that demonstrates things really do
indeed seem to work.
Tested:
* AR9462 (WB222), STA mode + bt
* QCA9565 (WB335), STA mode + bt
TODO:
* .. the rest of coexistence. yes, bluetooth, not people. That stuff's hard.
* It doesn't do the initial BT side calibration, which requires a WLAN chip
reset. I'll fix up the reset path a bit more first before I enable that.
* The 1-ant and 2-ant configuration bits aren't being set correctly in
if_ath_btcoex.c - I'll dig into that and fix it in a subsequent commit.
* It's not enabled by default for WB222/WB225 even though I believe it now
can be - I'll chase that up in a subsequent commit.

Adding .META to targets-to-build will ensure that they will rebuild if there
is no .meta file.
Adding it to all SUFFIXES and objects ensures that at least objects will
rebuild if there is no .meta file.
This will be reverted if bmake's behavior changes to rebuild on missing .meta
files.

Support for the new hashing algorithms in ZFS was introduced in r289422
However it was disconnected because FreeBSD lacked implementations of
SHA-512 (truncated to 256 bits), and Skein.
These implementations were introduced in r300921 and r300966 respectively
This commit connects them to ZFS and enabled these new checksum algorithms
This new algorithms are not supported by the boot blocks, so do not use them
on your root dataset if you boot from ZFS.

includes the FDT option. Use OPT_FDT to conditionally compile modules
that require FDT support.
In the past we've gotten away with using the arch name as a proxy for FDT
support in makefile conditional logic, but now mips has some platforms with
fdt support and some without and we need a more direct test.
This allows using META_MODE directly from the kernel build directory.
This also allows removing a hack from the DIRDEPS_BUILD kernel target.

This patchset adds support to bhnd_chipc for sharing SYS_RES_MEMORY
resources with its children, allowing us to hang devices off of
bhnd_chipc that rely on access to a subset of the device register space
that bhnd_chipc itself must also allocate.
We could avoid most of this heavy lifting if RF_SHAREABLE+SYS_RES_MEMORY
wasn't limited to use with allocations at the same size/offset.
As a work-around, I implemented something similar to vga_pci.c, which
implements similar reference counting of of PCI BAR resources for its
children.
With these changes, chipc will use reference counting of SYS_RES_MEMORY
allocation/activation requests, to decide when to allocate/activate/
deactivate/release resources from the parent bhnd(4) bus.
The requesting child device is allocated a new resource from chipc's
rman, pointing to (possibly a subregion of) the refcounted bhnd resources
allocated by chipc.
Other resource types are just passed directly to the parent bhnd bus;
RF_SHAREABLE works just fine with IRQs.
I also lifted the SPROM device code out into a common driver, since this
now allows me to hang simple subclasses off of a common driver off of both
bhndb_pci and bhnd_chipc.
Tested:
* (landonf) Tested against BCM4331 and BCM4312, confirmed that SPROM still
attaches and can be queried.
