This commit improves the script used to generate the patches from the
upstream git repo. Basically, it removes even more cruft that was
being added by 'git format-patch', making the output really simple and
deterministic (determinism which was a problem before).
Aside from the metadata, nothing else has been changed and therefore
it doesn't justify a new Fedora GDB release.
- chmod +x on the generate-*.sh script.s
- Remove references to gdb-8.0.1 from 'sources' and '.gitignore'.
- Regenerate first line of the patches (remove commit hash).
- Fix empty Source line.
- [archer-tromey-delayed-symfile] New test gdb.dwarf2/dw2-aranges.exp.
- [archer-keiths-expr-cumulative+upstream] Import C++ testcases.
- testsuite: Fix gdb-test-expr-cumulative-archer.patch compatibility.
