Subject: [PATCH] Bug 34943: Implement `before_biblio_metadata_store` plugin
 hook
MIME-Version: 1.0
Content-Type: text/plain; charset=utf8
Content-Transfer-Encoding: 8bit

This patch implements a hook allowing record modification right before
they are written on the DB. The idea is that a plugin could be used to
add machine-generated fields/subfields.

To test:
1. Apply the unit tests patch
2. Run:
   $ ktd --shell
  k$ prove t/db_dependent/Koha/Plugins/Biblio_and_Items_plugin_hooks.t
=> FAIL: Tests fail! The hook is not implemented so the desired results
don't appear (added fields/subfields).
3. Apply this patch
4. Repeat 2
=> SUCCESS: It works!
5. Run:
  k$ qa -c 2
=> SUCCESS: All green!
6. Sign off :-D
