two halves: stacktrace.c, which deals with getting, traversing and printing stack traces; and execontext.c, which deals with storing stack traces permanently in a way that avoids duplicates, and comparing them. One nice outcome: previously we were often creating ExeContexts, which live forever, even when they were only needed temporarily. Ie. this was a memory leak, which has been removed. As part of this, new headers have been created, carved off core.h and tool.h. Lots of function names have changed, too. In Massif, I also changed a lot of "eip" names to "ip" to make them less x86-specific. git-svn-id: svn://svn.valgrind.org/valgrind/trunk@3429
