[PATCH 00/28] Revamping the attr subsystem!

[Stefan Beller <sbeller@google.com>]

This is a series that
* replaces jc/attr-more. I did merge one fixup! commit at the appropriate place,
  as well as resolving a minor merge conflict when rebasing to the latest master
* revamps the API of the attr subsystem, such that it can be made thread safe
  in a later step easily, because the expected changes are only in attr.c
  
I think this is a start to the minimal set of changes such that we can rebase
sb/pathspec-label and sb/submodule-default-paths on top of these eventually.

Thanks,
Stefan
