This reverts commits b21c17eee9 and 2f78338aeb.
'Debug Fmod' was not an intended commit, was meant for local testing. But might be a good idea to make this a part of DebWithRelInfo or provide a cmake switch.
This particular case of LLAPRFile crashes due to thread issues (and if it doesn't it might be affecting some other apr call due to using default pool).
Function is not opening the .dsf file in question and LLAPRFile won't ensure that file exists till the end of the function, it just checks that file exists at a given moment. No point to overcomplicate things by adding thread safe pool, so replaced with dirutil.
