- Copy stable/10 (r259064) to releng/10.0 as part of the
10.0-RELEASE cycle.
- Update __FreeBSD_version [1]
- Set branch name to -RC1

[1] 10.0-CURRENT __FreeBSD_version value ended at '55', so
start releng/10.0 at '100' so the branch is started with
a value ending in zero.

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.

Add missing and probably also mandatory -h option.

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.

Add support for filtering USB devices and USB endpoints to the usbdump utility
when making software USB traces.

Make the usbdump utility work again by using the correct BPF structures.

Minor usbdump update:
- Use memcpy() instead of bcopy().
- Replace all asserts() by standard error messages.
- Update usage().

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.
