[PATCH 04/20] dwarf-reader split: create abg-symtab-reader.{h, cc} and test case

[Matthias Maennich <maennich@google.com>]

abg-symtab-reader.{h,cc} shall contain the refactored symtab reader.
Create the stub files, an empty unit test and hook everything up in the
make system.

    * src/abg-symtab-reader.h: New header file.
    * src/abg-symtab-reader.cc: New source file.
    * src/Makefile.am: Add new source files.
    * tests/Makefile.am: Add new test case runtestsymtabreader.
    * tests/test-symtab-reader.cc: New test source file.
