Our mm_malloc, mm_calloc, etc functions were all exported, since C hasn't got a nice portable way to say "we want to use this function inside our library but not export it to others". But they apparently conflict with anything else that calls its symbols mm_*, as libmm does. This patch renames the mm_*() functions to event_mm_*_(, and defines maros in mm_internal so that all the code we have that uses mm_*() will still work. New code should also prefer the mm_*() macro names. Reported by Gernot Tenchio. Fixes sf bug 2996541
