[PATCH v2 0/2] update internal patch-id to use "stable" algorithm

["Jerry Zhang via GitGitGadget" <gitgitgadget@gmail.com>]

Internal usage of patch-id in rebase / cherry-pick doesn't persist
patch-ids, so there's no need to specifically invoke the unstable variant.

This allows the unstable logic to be cleaned up.

In the process, fixed a bug in the combination of --stable with binary files
and header-only, and expanded the test to cover both binary and non-binary
files.
