Add DRMFILE definitions and supply filp for BSD in the
post-drm-filp-0-1-branch world. The filp is a void * cast from the current pid. This is a temporary solution which maintains the status quo until a proper solution is implemented. What is really needed is a unique pointer per open, hopefully with a device private area. This can be done in FreeBSD for all entry points except mmap, but is difficult (sys/dev/streams/streams.c is an example). I have partially completed code for this but have not had time to debug, so this is a temporary fix.
