- 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.

Fix build for gcc users by declaring variables for unions in structs which
don't declare a variable. The size before/after this change of the structs
doesn't change with gcc/clang.

- Move videodev headers from compat/linux to contrib/v4l (cp from vendor and
apply diff to compat/linux versions).
- The cp implies an update of videodev2.h to the linux kernel 2.6.34.14 one.

The update makes video in skype v4 work on FreeBSD.

(update of header only)

Update videodev2.h to the version from linux kernel 2.6.34.14.
This version is dual-licensed: 3 clause BSD license and GPL v2+.

Add the v4l2 header now that we have an use case for it.

Import the interface description of the video for linux (v4l) subsystem.
The header is importet from linux 2.6.17.

The header does not come with a license, the author
(Alan Cox <alan@redhat.com>) gave his permission to use it (note, X.org
has a copy of the header too):
