[PATCH v1 0/2] Introduce asinfo tool

[Edgar Kaziahmedov]

1.Separate common subroutines for asinfo and strace to avoid duplication of code.
Moreover, it will be useful for any complementary tool in the strace package.
2.This version is refactored(in sense of arch_dispatcher) and for now, concerning
syscalls, tool is able to dump name of syscall using its number. The remainig options
are blocked for a while.
