Bug 9830: Fix some indexes in UNIMARC item indexing

Bug 9830: Fix some indexes in UNIMARC item indexing

With this combination of sysprefs, and a UNIMARC configuration, it was
impossible to search on location, barcode and ccode indexes :

QueryWeightFields          is activated
QueryAutoTruncate          only if * is added

But in UNIMARC, location, barcode and ccode (995 $e,$f,h) were indexed
only as "words". They need to be indexed also as "phrase".

Additionnaly, in UNIMARC, information about damaged and withdrawn status
of items is not indexed, while it is done in MARC21.

This patch
- add 2 new indexes for 995$1 (damaged) and 995$3 (withdrawn)
- index location, barcode and ccode as "phrase" as well as "words"

Indexing of items in UNIMARC could be improved later. So this patch also
add comments explaining the origin of Koha 995, I think it could be
useful for further changes.

To test, on a UNIMARC configuration :
A. indexed with GRS-1
1) Set sysprefs QueryWeightFields as "activated" and QueryAutoTruncate
   as "only if * is added"
2) Select location index in advanced search and search for a value
   existing in your records in 995$e => 0 results
3) Apply patch
4) Rebuild zebra
5) Select location index in advanced search and search for a value
   existing in your records in 995$e => x results
6) Mark an item as withdrawn; search "withdrawn:1" => x results, and
   among them the biblio to which the item is attached
7) Mark an item as damaged ; search "damaged:1" => x results, and among
   them the biblio to which the item is attached

B. indexed with DOM
Do the same operations

Work as described. No koha-qa errors

Test
Apply the patch
Begin with GRS-1
Full reindex
Search by location, no results
cp files biblio-*-indexdefs.xml and record.abs to destination on etc/zebra
Full reindex
Search by location, got results

Switch to DOM
reset files
Full reindex
Search by location, no results
cp files
Full reindex
Search by location, results !
