Bug#1033627: exporttree=yes data loss

[Joey Hess]

Package: git-annex
Version: 10.20230126-2
Severity: important

git-annex has this bug, which can result in data loss when using an 
external special remote with exporttree=yes
https://git-annex.branchable.com/bugs/external_remote_export_sent_to_wrong_process/

This is fixed in version 10.20230329.

I've attached a patch series that fixes this. Note that the second patch
is not strictly necessary, but it's all that's needed to support
VERSION 2, which some external special remote programs will now be
using to avoid being used with the buggy git-annex. So, I strongly
recommend including it.

(The patches are lightly trimmed versions of upstream commits 
02662f52920e84cd9464641ada84f6c3bbe3f86a and
18d326cb6f27912542f41fbb9525eefdbd553d09)
