Subject: [PATCH] Add private API for finding symbols on Linux

Add an API for use by declarative that allows searching for a
symbol that has been loaded, without opening a specific library.
This makes it possible for declarative to determine if the
profiling library has been preloaded, and to call functions on
it that enable / disable / save the current profile.
