memprof: add memory profiling using LD_PRELOAD
This brings over some of the techniques from the old memprof design. Sysprof and memprof shared a lot of code, so it is pretty natural to bring back the same callgraph view based on memory allocations. This reuses the StackStash just like it did in memprof. While it would be nice to reuse some existing tools out there, the fit of memprof with sysprof is so naturally aligned, it's not really a big deal to bring back the LD_PRELOAD. The value really comes from seeing all this stuff together instead of multiple apps. There are plenty of things we can implement on top of this that we are not doing yet such as temporary allocations, cross-thread frees, graphing the heap, and graphing differences between the heap at to points in time. I'd like all of these things, given enough time to make them useful. This is still a bit slow though due to the global lock we take to access the writer. To improve the speed here we need to get rid of that lock and head towards a design that allows a thread to request a new writer from Sysprof and save it in TLS (to be destroyed when the thread exits).
