Breakpad Linux/Mac symbol dumper: Share duplicate strings that arise in DWARF data.
This patch avoids allocating many copies of identical strings appearing in debugging information. Without this patch, running dump_syms on Mozilla's libxul.so (with 173MiB of debugging information) has a peak resident set of around 450MiB. With this patch, the peak is around 365MiB. a=jimblandy, r=mark git-svn-id: http://google-breakpad.googlecode.com/svn/trunk@626 4c0a9323-5329-0410-9bdc-e9ce6186880e
