fixed by using an updated libbacktrace

A WIP for this can be found in wip/buildid, it will include the buildid in the heaptrack file. But for interpreting, it isn't enough to just load the debug file only. It has to be used in addition apparently, which isn't possible without patching libbacktrace like is done in vogl.

some ideas on how to do it:

need to add configuration for the editor preferences, similar to what gammaray does

additionally, we could try to use seccomp(-bpf) to get notified about mmap syscalls via SIGSYS, but I'm not sure whether we get access to the syscall args from the interrupt handler

there's now a public heaptrack_api.h for pool allocators.

On a 32bit machine:

We should look at rr, and how they monkey-patch the vdso to trace all syscalls. That could be used then to track I/O and futex stuff. It would also be useful for heaptrack itself to trace mmap/munmap/sbrk to check heapspace vs. the "real" requested memory by the allocator.
