generate_eh_elf: compile in C to avoid name mangling
...
This made symbol lookup problematic…

Use those functions in stack_walked.cpp test

Move _fde_func_t typedef to shared .h

Add fde_handler_for_pc (untested)
...
This is an abstraction function to get the _fde_yyy function out of the
eh_elf for a given PC

Add a simple stack_walker test

Add a tentative stack walker using eh_elfs
...
This is only a beginning: this does so far load the appropriate
eh_elf.so files and read a context. Unwinding is still absent.

Check mtime to avoid recreating existing so

Refactor code generation: use shared/context_struct.h
...
This allows #include'ing `context_struct.h` in the stack walker
implementation as well

Remove debug output

Allow unimplemented registers to appear in DWARF
...
The presence of such a register — eg. rcx, which is actually used in CFA
on a few lines of libgcc_s.so on my system — will yield an assert(0) in
the produced code, but will at least not fail to compile alltogether.

Add simplistic Dwarf representation
...
This is only representing a small fragment of Dwarf, **on purpose**: in
practice, the huge majority of Dwarf observed in the wild belongs to
this fragment.
