PerfTools/JeProf: Make a library that allows a call to jemalloc profile heap dump function.

[gartung]

The proposed usage would be to add <use="PerfTools/JeProf" /> to a package Buildfile.xml and then make a call to cms::jeprof::makeHeapDump() in your module code to produce a Heap Profile with the filename passed as an argument when your module config is run with cmsRunJEProf
