DWC OTG driver. Fix a hang issue when using LOW and FULL speed
BULK traffic. Make sure we don't ask for data in the last
microframe. This allows using devices like USB mice and USB
keyboards connected to the RPI-B.

the 'PREVENT/ALLOW MEDIUM REMOVAL' SCSI command. An example of such a
device is the STmicro ST72682. We send the SCSI command for every open and
close, which can result in a significant amount of spam on the console
during boot.

temporarily stores characters if the TTY buffer is full when
used a as a console. This can happen when a console is suspended.
Also properly do the flow stop signalling when this happens and
flow start when the condition changes back to normal again.
Bump __FreeBSD_version to force external kernel modules
to be recompiled. No kernel API changes.

Also update the port reset time from 250ms to 50ms. Some USB devices
have a hard limit in hardware at 222ms for the port reset time and will
not enumerate unless this delay is closer to the usb.org defined value.
This patch can fix enumeration with some USB devices.

if_clone_simple()

to initialize a cloner, instead of macros that initialize if_clone

Note: This makes it possible to use lqr/echo in ppp.conf. And it
resolves ppp hanging during the PPp> phase.

set not-NULL during SIM registration and set to UMASS_GONE on destruction.
Debug messages there look broken for at least 9 years, as they dereference
softc value that was just checked to be equal to NULL.
- Remove magic pointer value UMASS_GONE and use simple NULL instead.

gone rule. Optimise use of channels so that when a channel
is not ready another channel is used. Instead of using the SOF interrupt
use the system timer to drive the host statemachine. This might
give lower throughput and higher latency, but reduces the CPU usage
significantly. The DWC OTG host mode support should not be considered
for serious USB host controller applications. Some problems are still
seen with LOW speed USB devices.
