hid: Replace USBHID_ENABLED kernel config option with loader tunable

usbhid(4) is disabled by default to avoid conflicts with existing USB HID
drivers. To enable it place following lines to /boot/loader.conf:

hw.usb.usbhid.enable=1
usbhid_load="YES"

hid: Import usbhid - USB transport backend for HID subsystem.

This change implements hid_if.m methods for HID-over-USB protocol [1].

Also, this change adds USBHID_ENABLED kernel option which changes
device_probe() priority and adds/removes PnP records to prefer usbhid
over ums, ukbd, wmt and other USB HID device drivers and vice-versa.

The module is based on uhid(4) driver. It is disabled by default for
now due to conflicts with existing USB HID drivers.

hid: Chase for HID function name changes in existing USB HID drivers

Also hide shim code added in a previous commit under COMPAT_USBHID12.

Note: it is enough to add -DCOMPAT_USBHID12 to CFLAGS to compile old
code with new HID subsystem, but it is not enough to link it at runtime.
HID dependency has to be added explicitly with MODULE_DEPEND macro.

wmt(4): Add support for hybrid mode

In Hybrid mode, the number of contacts that can be reported in one
report is less than the maximum number of contacts that the device
supports. For example, a device that supports a maximum of 4
concurrent physical contacts, can set up its top-level collection to
deliver a maximum of two contacts in one report. If four contact
points are present, the device can break these up into two serial
reports that deliver two contacts each.

usb: clean up empty lines in .c and .h files

wmt(4): Reapply r358872 (by hselasky) modified to use
maximal input report size instead of wMaxPacketSize.

If the USB frame length is set to 1024 bytes, WMT_BSIZE, the EETI controller
will pack multiple touch events in the packet and the current code will only
process the first touch event.

As a result some important events are lost like releasing the finger from the
touchscreen.

Use the maximal input report size as buffer size instead.

Mark more nodes as CTLFLAG_MPSAFE or CTLFLAG_NEEDGIANT (2 of many)

r357614 added CTLFLAG_NEEDGIANT to make it easier to find nodes that are
still not MPSAFE (or already are but aren’t properly marked). Use it in
preparation for a general review of all nodes.

wmt(4): Fix regression introduced in r337289

r337289 has a side effect of reducing usb frame 0 buffer size down to
touch report size. That broke some devices e.g. "Raydium Touch System"
which are capable of generating non-touch frames of bigger length.
Fix it with enlarging frame 0 buffer up to internal wmt(4) buffer size.

wmt(4): Use internal function to calculate input report size

Usbhid's hid_report_size() calculates integral size of all reports of given
kind found in the HID descriptor rather then exact size of report with given
ID as its userland counterpart does. As all input data processed by the
driver is located within the same report, calculate required driver's buffer
size with userland version, imported in one of the previous commits.
This allows us to skip zeroing of buffer on processing of each report.

While here do some minor refactoring.
