gprofng: Use prototype to call libc functions
libcollector may not link against libC.
We use dlsym() to get a function from libc.
In some files, pointers to these functions do not have prototypes.
I also moved the shared definitions to libcollector/collect.h.
gprofng/ChangeLog

libcollector/collector.c: Add prototypes.
libcollector/dispatcher.c: Likewise.
libcollector/heaptrace.c: Likewise.
libcollector/iotrace.c: Likewise.
libcollector/linetrace.c: Likewise.
libcollector/mmaptrace.c: Likewise.
libcollector/synctrace.c: Likewise.
libcollector/collector.h: Add CALL_REAL(), NULL_PTR(), and DBG_LT.
