This patch changes the report symbolization strategy that would be used by
sanitizer family of tools: as compiling in-process
symbolizer into ASan runtime involves certain difficulties, we may instead
launch an external symbolizer program (fork + execl) in a subprocess
and communicate with it via pipe. External symbolizer tool (I will sent its
draft for review in another patch) will read requests of the form

<module_path> <module_offset>

and output responses of the form


which is (somewhat) similar to addr2line format.
