Publishing writes the package symlink, the dist symlinks and the tarball,
with no transaction between them. A build killed part-way left the remote in
a state every later build refused to touch ("already exists on S3 but ...
does not", or "Conflicts detected" among the dist symlinks) until someone
cleaned it up by hand, and clients following the symlink got 404s meanwhile.
Write the package symlink with If-None-Match: * and let it arbitrate who
owns the revision. If it points at the store path we are about to write, any
leftovers are our own and we complete the publish; anything else still
aborts. Losing the claim to a build of the same hash is fine, but that build
may itself have died, so check for its tarball instead of assuming it will
finish.
The store must honour If-None-Match (CERN's Ceph RGW verifiably does);
ignoring it would silently restore the old racy behaviour, so there is no
fallback. botocore support is checked up front, and read-only use is
unaffected.

* Add new provenance tracking remote store back-end. Modeled after Google's REAPI. * Add install sub command to install packages without alidist and the need to build them. * Add reconstruct sub command to rebuild a tarball using the provenance information stored in the remote store ledger. * Add migrate sub command to populate the new reapi store with packages from the old store * Code-signing support for official tarballs
