Hi All,

Changes:
* When mmap gets passed an fd of -1 (anonymous map) don't look for it in our
   list of managed fds, as we use -1 to mark unused entries (fixes ekiga
   crashing). Also check for an fd of -1 in the other calls we intercept.
* In close() start with removing the fd from our list of managed fds, this must
   be done first, because as soon as we've done the actual close syscall, the
   fd maybe returned by an open in another thread and we don't want to intercept
   calls to this new fd.
* Make unknown v4l1 palette types a normal level log messages instead of an
   error.
* When an applicaiton changes the width / height through the CMCAPTURE ioctl
   remember the new width and height.
* If the devices initial v4l2 pixformat has no corresponding v4l1 palette, try
   setting a format which does (and which we emulate when necessary) so that
   applicactions which just query the current format (GPICT) and then take
   whatever they get will work (partially fixes camorama)
* Implement our own SWIN instead of using kernel compat layer, for more
   flexibility and better error checking

If you want to test please use this version, the previous version had a nasty 
bug in the mmap wrapping causing all kinda problems (brown paper bag bug).

New version attached.

Regards,

Hans
