Fix parsing of corrupt data in usbdump(8). Check that the transfer
type array lookup is within bounds to avoid segfault.

MFC r326276:

various: general adoption of SPDX licensing ID tags.

Mainly focus on files that use BSD 2-Clause license, however the tool I
was using misidentified many licenses so this was mostly a manual - error
prone - task.

The Software Package Data Exchange (SPDX) group provides a specification
to make it easier for automated tools to detect and summarize well known
opensource licenses. We are gradually adopting the specification, noting
that the tags are considered only advisory and do not, in any way,
superceed or replace the license texts.

No functional change intended.

Copy head@r302406 to stable/11 as part of the 11.0-RELEASE cycle.
Prune svn:mergeinfo from the new branch, as nothing has been merged
here.

Additional commits post-branch will follow.

Fix for big endian architectures. The "up_address" field is 8-bit and
does not need byte swapping.

Make usbusN logging pseudo-interface used by usbdump(8) clonable. One is
now created/destroyed automatically by usbdump(8).

Note that "hw.usb.no_pf" loader tunable is now obsolete.

Improve support for USB packet filtering also when reading dumps, and
allow filtered data to be dumped to a binary file.

Create new file header format to simplify the endian and cross platform issues.
This patch does not break binary compatibility with previous versions.

MFC after: 1 week

Fix cross-platform issue about the file-format in which
usbdump stores data. Until this patch it was not possible
to exchange traces between 32-bit, 64-bit, big- and
little endian platforms. The problem is the dynamic nature
of the BPF timestamp in the header. All other fields are
fixed size and little endian.

fix printing of tv_usec

- Improvements to USB PF solution
- Add more fields for USB device and host mode
- Add more information to USB PF header so that decoding
can easily be done by software analyzer tools like
Wireshark.
- Optimise usbdump to display USB streams in text format
more efficiently.
- Software using USB PF must be recompiled after
this commit, due to structure changes.

- Remove double semicolon.
- Remove reference to sprintf. Use printf directly. This part of
the code should be optimised further to avoid many small printouts.
Setting a sensible line buffer length could help aswell when printing
out megabytes of data per second.

Approved by: thompsa (mentor)

Changes the meaning of each characters '<' and '>' that it could be
confused with USB OUT or USB IN packets though it just represents USB
submit or done. To know the USB packet direction, the endpoint address
should be referred.

Requested by: jkim

As a refection of r215802 it should use BPF interfaces because the
duplication code of USB pf is removed.

Adds usbdump(8) tool that currently it only supports the very basic
feature set. It's not connected to the build yet.
