Nick Clemens 88cb7f223d Bug 25265: Prevent double reindex of the same item in batchmod
When batch editing, 2 reindex calls are sent to ES/Zebra.
We can easily avoid that reusing the skip_modzebra_update (renamed skip_record_index)

Additionally we should only send one request for biblio, and we should
only do it if we succeed

As the whole batch mod is in a transaction it is possible to fail in which case
Zebra queue is reset, but ES indexes have already been set

In addition to the skip param this patchset moves Zebra and Elasticsearch calls to
Indexer modules and introduces a generic Koha::SearchEngine::Indexer so that we don't
need to check the engine when calling for index

The new index_records routine takes an array so that we can reduce the calls to
the ES server.

The index_records routine for Zebra loops over ModZebra to avoid affecting current behaviour

Test plan:

General tests, under both search engines:
  1 - Add a biblio and confirm it is searchable
  2 - Edit the biblio and confirm changes are searchable
  3 - Add an item, confirm it is searchable
  4 - Delete an item, confirm it is not searchable
  5 - Delete a biblio, confirm it is not searchable
  6 - Add an authority and confirm it is searchable
  7 - Delete an authority and confirm it is not searchable

Batch mod tests, under both search engines
  1 - Have a bib with several items, none marked 'not for loan'
  2 - Do a staff search that returns this biblio
  3 - Items show as available
  4 - Click on title to go to details page
  5 - Edit->Item in a batch
  6 - Set the not for loan status for all items
  7 - Repeat your search
  8 - Items show as not for loan
  9 - Test batch deleting items
    a - Test with a list of items, not deleting bibs
    b - Test with a list of items, deleting bibs if no items remain where all items are only item on a biblio:
     SELECT MAX(barcode) FROM items GROUP BY biblionumber HAVING COUNT(barcode) IN (1)
    c - Test with a list of items, deleting bibs if no items remain where some items are the only item on a biblio:
     SELECT MAX(barcode) FROM items GROUP BY biblionumber HAVING COUNT(barcode) IN (1,2)
 10 - Confirm records are update/deleted as appropriate

Merge biblios linked to authority $mergefrom (mandatory parameter).
If $mergeto equals mergefrom, the linked biblio field is updated.
If $mergeto is different, the biblio field will be linked to $mergeto.
If $mergeto is missing, the biblio field is deleted.
MARCfrom is used to determine if a cleared subfield in the authority record
should be removed from a biblio. MARCto is used to populate the biblio
record with the updated values; if you do not pass it, the biblio field
will be deleted (same as missing mergeto).
Normally all biblio records linked to $mergefrom, will be considered. But
you can pass specific numbers via the biblionumbers parameter.
The parameter override_limit is used by the cron job to force larger
postponed merges.
Note: Although $mergefrom and $mergeto will normally be of the same
authority type, merge also supports moving to another authority type.
