Amended: Using items from Koha::Biblio seems better :)

Two discussions on koha-devel lead to the same conclusion:
biblioitems.marcxml should be moved out this table
- biblio and biblioitems
http://lists.koha-community.org/pipermail/koha-devel/2013-April/039239.html
- biblioitems.marcxml & biblioitems.marc / HUGE performance issue !
http://lists.koha-community.org/pipermail/koha-devel/2016-July/042821.html
There are several goals to do it:
- Performance
As Paul Poulain wrote, a simple query like
SELECT publicationyear, count(publicationyear) FROM biblioitems GROUP BY publicationyear;
takes more than 10min on a DB with more than 1M bibliographic records
but only 3sec (!) on the same DB without the biblioitems.marcxml field
Note that priori to this patch set, the biblioitems.marcxml was not
retrieved systematically, but was, at least, in
C4::Acquisition::GetOrdersByBiblionumber and C4::Acquisition::GetOrders
- Flexibility
Storing the marcxml in a specific table would allow use to store several
kind of metadata (USMARC, MARCXML, MIJ, etc.) and different formats (marcflavour)
- Clean code
It would be a first step toward Koha::MetadataRecord for bibliographic
records (not done in this patch set).
Test plan:
- Update the DBIC Schema
- Add / Edit / Delete / Import / Export bibliographic records
- Add items
- Reindex records using ES
- Confirm that the following scripts still work:
* misc/cronjobs/delete_records_via_leader.pl
* misc/migration_tools/build_oai_sets.pl
- Look at the reading history at the OPAC (opac-readingrecord.pl)
- At the OPAC, click on a tag, you must see the result
Note: Changes in Koha/OAI/Server/ListRecords.pm is planned on bug 15108.

Fix record matching in misc/cronjobs/delete_records_via_leader.pl

Recently added, delete_records_via_leader.pl reads biblioitems.marc as a
text field and search for record to delete regarding the leader 5.
This can be acchieve doing the same thing on biblioitems.marcxml (will
certainly be slower) waiting for a patch on bug 15537.
Test plan:
Confirm that this script works as before, to do so the easiest way would
be to dump your DB before executing the update DB entry, execute the
script to delete records, reinsert the DB, execute the udpate DB entry
(remove biblioitems.marc), execute the script to delete records.
You should get the same number of records deleted.

Position 05 of the leader in MARC 21 indicates the record's status.
A lower case 'd' indicates that the record is to be deleted
(http://www.loc.gov/marc/authority/adleader.html).
This patch adds a cronjob script that may be run nightly to delete
records where position 05 of the leader is set to 'd'.
Test Plan:
1) Edit one or more records, and set the leader position 05 to 'd'.
2) Run misc/cronjobs/delete_records_via_leader.pl -c -v
3) Those records should either be deleted, or an error message should
state why they were not.

Works as advertised. Edited a record with an item to have leader05 = d,
then ran delete_records_via_leader.pl with -c and got a message that
the record could not be deleted because of the item. Removed the item
and the script deleted the record. Tried with another record with an
item, this time with the -i option and the record was deleted.
