[PATCH/RFC 0/3] pedantic errors in next

Building next with pedantic enabled shows the following 2 issues that were originally in ew/many-alternate-optim, apologies for not catching them earlier.

the second one could be skipped, and has indeed another similar case already in seen which will be send separately.

the third patch adds a CI job that could be used to detect this issues early and that adds about 5m of computing time.

Carlo Marcelo Arenas Belón (3):
  oidtree: avoid nested struct oidtree_node
  object-store: avoid extra ';' from KHASH_INIT
  ci: run a pedantic build as part of the GitHub workflow
