registry: System registry cache file
Submitted by Dan Nicholson
Link to original bug (#748452)
Description
Right now, the first time a user runs a gstreamer program, it's slowed down by generating the registry cache file. Gstreamer should be able to try a system registry cache file if the user's cache file doesn't exist. See previous discussion here:
