This reverts commit c98e40ff.

Add a .git-blame-ignore-revs file to improve the output of git-blame(1) by ignoring large changes when introducing the Black source code reformatter and update the CONTRIBUTING.md guide on how to optionally use it locally.

Search for expected keywords in the output of cbfstool tests and not a specific output. (Closes: reproducible-builds/diffoscope!42)

Stop trying to track every small change in the output of the "cbfstool print"
command, just search for some expected keywords instead.

- Around 2015 the legacy master header stopped being generated by default:
   https://www.coreboot.org/CBFS#FMAP
   https://review.coreboot.org/c/coreboot/+/10135



- In v4.7, cbfstool added the Comp(ression) column.

- v4.8 or v4.9 added a new header " FMAP REGION: COREBOOT", see new

Support external build tools. (Closes: reproducible-builds/diffoscope#87, reproducible-builds/diffoscope!41)

Drop --max-report-size-child and --max-diff-block-lines-parent; scheduled for removal in January 2018.

(diff is kinda misleading; nothing is actually changed.)

Append a comment to a difference if we fallback to an inferior container format but we are missing a tool.

Add support for alternative container types for a file, allowing for runtime (vs import time) control of fallbacks such as adding comments. (Re: #86)

Factor-out the generation of "foo not available in path" comment messages into the exception that raises them.

Fallback to the regular .zip container support if apktool is not available by simply swapping out the container class at import-time. (Re: #86)

Alternative solution pending.

Rename diffoscope.locale module to diffoscope.environ as we are modifying things beyond just the locale (eg. calling tzset(), etc.)

Add the current PATH environment variable to the "Normalising locale..." debug-level logging message.

Log a debug-level message if we cannot open a file as container due to a missing tool to assist in diagnosing issues. (Re: #86)
