Bug 6440: Implement OAI-PMH Sets

New sql tables:
  - oai_sets: contains the list of sets, described by a spec and a name
  - oai_sets_descriptions: contains a list of descriptions for each set
  - oai_sets_mappings: conditions on marc fields to match for biblio to be
    in a set
  - oai_sets_biblios: list of biblionumbers for each set

New admin page: allow to configure sets:
  - Creation, deletion, modification of spec, name and descriptions
  - Define mappings which will be used for building oai sets

Implements OAI Sets in opac/oai.pl:
  - ListSets, ListIdentifiers, ListRecords, GetRecord

New script misc/migration_tools/build_oai_sets.pl:
  - Retrieve marcxml from all biblios and test if they belong to defined
    sets. The oai_sets_biblios table is then updated accordingly

Use OPACBaseURL in oai_dc xslt

---

To test:
 - Run updatedatabase.pl
 - Go to OAI Sets administration page (Administration > OAI Sets Configuration)
 - Create some sets with some mappings (mappings define if biblios belong to a
set or not, they're in the form of conditions FIELD$SUBFIELD = VALUE, multiple
conditions can be defined for a set)
 - Check some biblios are matching the conditions to belong to one set or more
 - Run misc/migration_tools/build_oai_sets.pl
 - Now you can test with $OPACBaseUrl/cgi-bin/koha/oai.pl

OAI-PMH spec is here http://www.openarchives.org/OAI/openarchivesprotocol.html

Some examples:

http://mylibrary.org/cgi-bin/koha/oai.pl?verb=ListSets
http://mylibrary.org/cgi-bin/koha/oai.pl?verb=ListRecords&metadataPrefix=oai_dc&set=set1
http://mylibrary.org/cgi-bin/koha/oai.pl?verb=ListIdentifiers&set=set2
http://mylibrary.org/cgi-bin/koha/oai.pl?verb=GetRecord&metadataPrefix=oai_dc&identifier=KOHA-OAI-TEST:3

The response of ListRecords and GetRecord must include setSpecs in header
