[PATCHv2 0/4] Some cleanups

[Stefan Beller <sbeller@google.com>]

v2:
Thanks Eric, Jeff, Junio for discussion, I picked up all hints and here
is a v2.

* drop the overallocation patches (1&2)
* use git_config_get_string instead of its _const equivalent, such that
  we don't need a cast when freeing in git_config_get_notes_strategy
* Use strbuf_list_free instead of cooking our own.
* have a dedicated error exit path in bundle.c, create_bundle

v1:
One of my first patches to Git were cleanup patches, and I fell back
to my old pattern here, while thinking on how to write better commit
messages for the submodule bugfixes I currently have in flight.

Just some one liners to not leak memory or file descriptors.

They are bundled as a series, but no patch relies on any predessor.

This applies on v2.8.0.

Thanks,
Stefan
