crash-stack: adding fallback heuristic method for unwinding

This reverts commit b7ef1fff4dd5f8f754df1431fe4b80fc1901b459,
which reverted commit f29763ccb1cf24bea7807b55ecd9722e3cb03743.

In case no better method is ready or available, this method
may yield some useful results. It simply walks over data stack
and checks word after word if it looks like an address from
any function. All such addresses are considered as call stack
functions. It should generally show all the called functions
that left any trace on the stack. However, among those there
may be a number of false positives.

This is currently used for x86_64 architecture.

Thus, this reverts commit ba3f2151f97c3e4bba1ac04c953f28ac4eb1e463,
which reverted commit 269790304eea1bde27644962efa7803c7ab611df.

To unwind call stack on aarch64 we need to use external
method, as libelf 0.153 does not support unwinding yet.
Possible methods are:
- using libunwind;
- manual walk with frame pointers;
- heuristic unwind by inspecting data stack.

This patch adds support for unwinding on aarch64 with frame pointers,
along with changes needed to modularize unwinding.
