Add support for decoding pressed keys as a bitmap. The keys in the
bitmap are described in the interface specific HID descriptor. Some
keyboards even have multiple input interfaces, only using the bitmap
method when the event array is full. That typically means when more
than seven keys are pressed simultaneously.
The internals of the USB keyboard driver have been slightly reworked
to keep track of all keys in a single bitmap having 256 bits. This
bitmap is then divided into blocks of 64-bits as an optimisation.
Simplify automatic key repeat logic, because only the last key pressed
can be repeated.

r356087 made it rather innocuous to double-register built-in keyboard
drivers; we now set a flag to indicate that it's been registered and only
act once on a registration anyways. There is no misleading here, as the
follow-up kbd_delete_driver will actually remove the driver as needed now
that the linker set isn't also consulted after kbdinit.
Keyboard drivers are generally registered via linker set. In these cases,
they're also available as kmods which use KPI for registering/unregistering
keyboard drivers outside of the linker set.
For built-in modules, we still fire off MOD_LOAD and maybe even MOD_UNLOAD
if an error occurs, leading to registration via linker set and at MOD_LOAD
time.
This is a minor optimization at best, but it keeps the internal kbd driver
tidy as a future change will merge the linker set driver list into its
internal keyboard_drivers list via SYSINIT and simplify driver lookup by
removing the need to consult the linker set.
Most keyboard drivers are using the genkbd implementations as it is;
formally use them for any that aren't set and make
genkbd_get_fkeystr/genkbd_diag private.
These invocations were directly calling enkbd_diag(), rather than
indirection back through kbdd_diag/kbdsw. While they're functionally
equivent, invoking kbdd_diag where feasible (i.e. not in a diag
implementation) makes it easier to visually identify locking needs in these
other drivers.
The datasheets for these chips claim the maximum is 921,600, but testing
shows these two higher rates also work (but no rates above 921,600 other
than these two work; these represent dividing the base buad clock by 3 and 2
respectively).

When epoch(9) was introduced to network stack, it was basically
dropped in place of existing locking, which was mutexes and
rwlocks. For the sake of performance mutex covered areas were
as small as possible, so became epoch covered areas.
However, epoch doesn't introduce any contention, it just delays
memory reclaim. So, there is no point to minimise epoch covered
areas in sense of performance. Meanwhile entering/exiting epoch
also has non-zero CPU usage, so doing this less often is a win.
Not the least is also code maintainability. In the new paradigm
we can assume that at any stage of processing a packet, we are
inside network epoch. This makes coding both input and output
path way easier.
On output path we already enter epoch quite early - in the
ip_output(), in the ip6_output().
This patch does the same for the input path. All ISR processing,
network related callouts, other ways of packet injection to the
network stack shall be performed in net_epoch. Any leaf function
that walks network configuration now asserts epoch.
Tricky part is configuration code paths - ioctls, sysctls. They
also call into leaf functions, so some need to be changed.
This patch would introduce more epoch recursions (see EPOCH_TRACE)
than we had before. They will be cleaned up separately, as several
of them aren't trivial. Note, that unlike a lock recursion the
epoch recursion is safe and just wastes a bit of resources.

This allows replacing "sys/eventfilter.h" includes with "sys/_eventfilter.h"

pollution substantially.
EVENTHANDLER_DECLARE and EVENTHANDLER_LIST_DECLAREs were moved out of .c
files into appropriate headers (e.g., sys/proc.h, powernv/opal.h).
As a side effect of reduced header pollution, many .c files and headers no
longer contain needed definitions. The remainder of the patch addresses
adding appropriate includes to fix those files.
LOCK_DEBUG and LOCK_FILE_LINE_ARG are moved to sys/_lock.h, as required by

to this change).

sys/mutex.h inclusion need to be fixed. __FreeBSD_version has been bumped.
FDT data is sometimes used to configure usb devices which are hardwired into
an embedded system. Because the devices are instantiated by the usb
enumeration process rather than by ofwbus iterating through the fdt data, it
is somewhat difficult for a usb driver to locate fdt data that belongs to
it. In the past, various ad-hoc methods have been used, which can lead to
errors such applying configuration that should apply only to a hardwired
device onto a similar device attached by the user at runtime. For example,
if the user adds an ethernet device that uses the same driver as the builtin
ethernet, both devices might end up with the same MAC address.
These changes add a new usb_fdt_get_node() helper function that a driver can
use to locate FDT data that belongs to a single unique instance of the
device. This function locates the proper FDT data using the mechanism
detailed in the standard "usb-device.txt" binding document [1].
There is also a new usb_fdt_get_mac_addr() function, used to retrieve the
mac address for a given device instance from the fdt data. It uses
usb_fdt_get_node() to locate the right node in the FDT data, and attempts to
obtain the mac-address or local-mac-address property (in that order, the
same as linux does it).
The existing if_smsc driver is modified to use the new functions, both as an
example and for testing the new functions. Rpi and rpi2 boards use this
driver and provide the mac address via the fdt data.

The GMII control bit ETH_MAC_CR_GMII_EN_ is not documented in
LAN78xx datasheets, but from the permissively licensed header provided
by Microchip it is:
#define ETH_MAC_CR_GMII_EN (0x00080000UL ) // GMII/RGMII Selection
is that current one (mass storage device) doesn't work as it is - it
needs to be set to 0 after the LUN is configured, which is what the
cfumass rc script does. In other words: the current default does not
work, and to actually make it work it had to be set to -1 in
/boot/loader.conf.

Previously lan78xx_chip_init locked the driver's mutex if not already
locked, but unlocked it only in the case of error. This provided a
fairly clear indication that the function is already called with the
lock held, so just replace it with a lock assertion.

This driver was developed for the LAN7800 and the register-compatible
LAN7515 and has only been tested on those devices. Adding support for
other members of the family should be straightforward, once we have
devices to test.
With this change the driver will probe but fail to attach due to the
Chip ID check, but will leave a hint leading to the driver that needs
work.

This change adds support for a UBS<->RS232 adapter based on CH340 (or an
analogue) that I own. The device seems to have a newer internal version
(0x30) and the existing code incorrectly configures line control for it
resulting in garbled transmission. The changes are based on what I
learned in Linux drivers for the same hardware.
Additional changes:
- use UCHCOM_REG_LCR1 / UCHCOM_REG_LCR2 instead of explicit 0x18 and
0x25
- use NULL instead of 0 where a pointer is expected

Also, add definitions for more bits of UCHCOM_REG_LCR1 as seen in the
Linux driver. UCHCOM_LCR1_PARENB definition was different from that in
the Linux driver and clashed with newly added UCHCOM_LCR1_RX. I took a
liberty to change UCHCOM_LCR1_PARENB to the Linux definition as it was
unused in the driver anyway. This change should make
uchcom_cfg_set_break() easier to understand.

Product IDs are specified in vendor documents. The previously used
device ID is not. This is a cosmetic change. No functionality depends
on those IDs.
