Header refactoring: ctl - unify and remove from catchall. In order to do this, we introduce the mutex_prof module, which breaks a circular dependency between ctl and prof.

Header refactoring: tsd - cleanup and dependency breaking. This removes the tsd macros (which are used only for tsd_t in real builds). We break up the circular dependencies involving tsd. We also move all tsd access through getters and setters. This allows us to assert that we only touch data when tsd is in a valid state. We simplify the usages of the x macro trick, removing all the customizability (get/set, init, cleanup), moving the lifetime logic to tsd_init and tsd_cleanup. This lets us make initialization order independent of order within tsd_t.

Remove mutex_prof_data_t redeclaration. Redeclaration causes compilations failures with e.g. gcc 4.2.1 on FreeBSD. This regression was introduced by 89e2d3c12b573310e60b97beaf178007a71d83a3 (Header refactoring: ctl - unify and remove from catchall.).
