Bug 6434 - Ukrainian and Russian MARC sql-tables

Bug 6434 - Ukrainian and Russian MARC sql-tables

Changes: Marc21 support, 995 for items (Unimarc), authorities types for both
MARC's, many small field/subfield changes

Signed-off-by: Frédéric Demians <f.demians@tamil.fr>
It works, doesn't break anything, seems to be in Ukrainian/Russian (I can't
judge).

It's a huge patch (21M). That's why it's attached as a bz2 archive: so the
archive must be downloaded, decompressed, and then applied.

General remark: Adding this patch to Koha will increase substantially Koha git
repository size. It shows that non-code files (.po files, SQL files)
could/should be managed outside Koha core repository. See this discussion:

Here is my test plan:

[1]  Apply the patch on master
[2]  Install ru-RU and uk-UA languages:
     cd misc/translator
     ./translate ru-RU uk-UA
[3]  re-create Koha DB:
     DROP DATABASE koha;
     CREATE DATABASE koha;
[4]  Load Koha pro interface: get web installer
[5]  Choose ru-RU language
[6]  Everything is in Russian. Click blindly on button until reaching the
     page where to choose Unimarc/Marc21.
[7]  Choose Unimarc.
[8]  Tick on everything to load all UNIMARC SQL files.
[9]  All SQL are loaded without any error.
[10] Check Koha cataloguing.
[11] Go to [3] and choose Marc21 at step [7].
[12] Go to [3] and choose uk-UA at step [5].
[13] Go to [3] and choose uk-UA at step [5] and Marc21 at step [7].
