patches 0.0-1.ef1b8a7 Patch tracking tool

Patches is a patch-tracking tool initially written for the QEMU project. It provides commands that build a database of patches from a mailing list, and commands that can search that database. It allows users to track the status of a patch, apply patches, and search for patches---all that from the command-line or from Emacs via its Notmuch integration.
