I came across commit 5c2726f "[core] rename lib apr symbols to fspr" while diving into the internals of FreeSWITCH and figuring out why the generated Doxygen docs don't point to the correct definitions for the most basic functions (e.g., `switch_mutex_lock`).

I'm pretty sure the commit above has nothing to due with the Doxygen issue, but now I'm curious what the rationale was behind that massive renaming task?

I'm new to C and APR, so I guess that was for debugging purposes only? Or were the APR functions re-written also?
