Refactor profiling

Browse Source 
Refactored core profiling codebase into two logical parts:

(a) `prof_data.c`: core internal data structure managing & dumping;
(b) `prof.c`: mutexes & outward-facing APIs.

Some internal functions had to be exposed out, but there are not
that many of them if the modularization is (hopefully) clean enough.
