Breakpad symbol dumper: Move Linux dumping classes into src/common.
The Linux symbol dumper's classes are reasonably portable, and should be usable for the Mac dumper as well. Move them to src/common, along with their unit tests. Update #include directives and Makefile. a=jimblandy, r=nealsid git-svn-id: http://google-breakpad.googlecode.com/svn/trunk@567 4c0a9323-5329-0410-9bdc-e9ce6186880e
