[CFT] New version of webcamd, now v4.8.0.2

Hi,

If you are using webcamd, please help test the latest version which 
includes the most recent Linux v4.8-rc1 media tree sources.

The latest webcamd port is available from here:

svn --username anonsvn --password anonsvn \
       checkout svn://svn.turbocat.net/i4b/trunk/ports/multimedia/webcamd

Please test and report any regression issues to me or 
freebsd-multimedia_at_freebsd.org

Changes:
- updated all Linux kernel sources to the latest Linux' Torvalds
- fixed some minor bugs in the webcamd Linux kernel emulation
- improved Linux kernel emulation support
- added support for the coming evdev kernel module (GSOC project)
