- `git format-patch --zero-commit` doesn't affect `index xxx...yyy` lines, only `From: `
- so use the _classy_ "use a regex with a callback" solution as git format-patch doesn't offer one
- this will make _all_ patches change when rewritten, but hopefully _for the last time_ !
- we need to preserve `index 000000000000..xxx` as zeros, which indicate new file creation, thus:
- new file creations are rewritten as `index 000000000000..111111111111`
- non-creations are rewritten as `index 111111111111..222222222222`
- this is the final version of #6455
This fixes the readability of colorized output of compile.sh when
running on a terminal with a light background. It uses the COLORFGBG
environment variable similarly to how the ip(8) command does.

- even Rich'er patch output by colorizing certain strings green/yellow/red
- BASE_GIT_TAG now very sneakily also accepts a branch name
- IMPORTANT: this includes: BREAKING CHANGE: patches failing to apply now break the build. fixes#4958
- also break on legacy `process_patch_file()` failure, remove `EXIT_PATCHING_ERROR`
- don't show stats for patches that are bind applied blind (failed to parse/autogen)
- don't show Author, it's too long
- don't dump Python exceptions in log
- extra: expand Python imports
