hid: Import functions and constants required by new subsystem

This does an import of quirk stubs, debugging macros from USB code and
numerous usage constants used by dependent drivers.

Besides, this change renames some functions to get a better matching
with userland library and NetBSD/OpenBSD HID code. Namely:

- Old hid_report_size() renamed to hid_report_size_max()
- New hid_report_size() calculates size of given report rather than
maximum size of all reports.
- hid_get_data_unsigned() renamed to hid_get_udata()
- hid_put_data_unsigned() renamed to hid_put_udata()

Compat shim functions are provided in usbhid.h to make possible compile
of legacy code unmodified after this change.

Fix bogusly declared WERRORs in kernel build

Many arm kernel configs bogusly specified WERROR=-Werror. There's no
reason for this because the default is that and there's no reason to
override. These date from a time when we needed to add additional
warning->error suppression. They are obsolete and were cut and paste
propagated from file to file.

Comment out all the WERROR=.... lines in powerpc. They aren't bogus,
but were appropriate for the old defaults for gcc4.2.1. Now that we've
made the policy decision to suppress -Werror by default on these
platforms, it is appropriate to comment these out. People wishing to
fix these errors can still un-comment them out, or say WERROR=-Werror
on the command line.

Fix two instances (cut and paste propagation) of hard-coded -Werror
in x86 code. Replace with ${WERROR} instead. This is a no-op change
except for people who build WERROR=-Wno-error :).

This should fix tinderbox / CI breakage.

tun/tap: merge and rename to `tuntap`

tun(4) and tap(4) share the same general management interface and have a lot
in common. Bugs exist in tap(4) that have been fixed in tun(4), and
vice-versa. Let's reduce the maintenance requirements by merging them
together and using flags to differentiate between the three interface types
(tun, tap, vmnet).

This fixes a couple of tap(4)/vmnet(4) issues right out of the gate:
- tap devices may no longer be destroyed while they're open [0]
- VIMAGE issues already addressed in tun by kp

[0] emaste had removed an easy-panic-button in r240938 due to devdrn
blocking. A naive glance over this leads me to believe that this isn't quite
complete -- destroy_devl will only block while executing d_* functions, but
doesn't block the device from being destroyed while a process has it open.
The latter is the intent of the condvar in tun, so this is "fixed" (for
certain definitions of the word -- it wasn't really broken in tap, it just
wasn't quite ideal).

ifconfig(8) also grew the ability to map an interface name to a kld, so
that `ifconfig {tun,tap}0` can continue to autoload the correct module, and
`ifconfig vmnet0 create` will now autoload the correct module. This is a
low overhead addition.

(MFC commentary)

This may get MFC'd if many bugs in tun(4)/tap(4) are discovered after this,
and how critical they are. Changes after this are likely easily MFC'd
without taking this merge, but the merge will be easier.

I have no plans to do this MFC as of now.

In the TCP stack, the hhook(9) framework provides hooks for kernel modules
to add actions that run when a TCP frame is sent or received on a TCP
session in the ESTABLISHED state. In the base tree, this functionality is
only used for the h_ertt module, which is used by the cc_cdg, cc_chd, cc_hd,
and cc_vegas congestion control modules.

Presently, we incur overhead to check for hooks each time a TCP frame is
sent or received on an ESTABLISHED TCP session.

This change adds a new compile-time option (TCP_HHOOK) to determine whether
to include the hhook(9) framework for TCP. To retain backwards
compatibility, I added the TCP_HHOOK option to every configuration file that
already defined "options INET". (Therefore, this patch introduces no
functional change. In order to see a functional difference, you need to
compile a custom kernel without the TCP_HHOOK option.) This change will
allow users to easily exclude this functionality from their kernel, should
they wish to do so.

Note that any users who use a custom kernel configuration and use one of the
congestion control modules listed above will need to add the TCP_HHOOK
option to their kernel configuration.

setenv bootargs video-mode=${video-mode}

at the u-boot CLI.
