media: staging: media: zoran: setup videocodec header for debugging macros

Browse Source 
This adds inline functions in the videocodec header file to convert the
videocodec and videocodec_master structs to their respective contained
zoran struct. This will be used to pass the zoran struct to the
zrdev_XXX() macros defined in the zoran header.

In the zoran header, the new include is added to ensure all variables
can be completely defined with the zoran and videocodec includes where
they are located.
