Tomas Cohen Arazi daf2ebc4f5 Bug 11096: support the retrieval of large MARCXML records 
This patch makes Koha <-> Zebra use MARCXML for the serialization when
using DOM, and USMARC for GRS-1.

* The following functions are modified to set the Zebra record syntax
according to the current sysprefs and configuration:

- C4::Context->Zconn
- C4::Context-_new_Zconn

* A new function 'new_record_from_zebra' is introduced, which checks the
context we are in, and creates the MARC::Record object using the right
constructor.

The following packages get touched to make use of the new function:
- C4::Search
- C4::AuthoritiesMarc

and the same happens to the UI scripts that make use of them (both in
the OPAC and STAFF interfaces).

* Calls to the unsafe ZOOM::Record->render()[1] method are removed.

Due to this last change the code for building facets was rewritten. And
for performance on the facets creation I pushed higher version
dependencies for MARC::File::XML and MARC::Record (we rely on
MARC::Field->as_string).

* Calls to MARC::Record->new_from_xml and MARC::Record->new_from_usmarc
are wrapped with eval for catching problems [2].

* As of bug 3087, UNIMARC uses the 'unimarc' record syntax. this case is
  correctly handled.
* As of bug 7818 misc/migration_tools/rebuild_zebra.pl behaves like:

- bib_index_mode (defaults to 'grs1' if not specified)
- auth_index_mode (defaults to 'dom')

here we do exactly the same.

To test:
 - prove t/db_dependent/Search.t should pass.
 - Searching should remain functional.
 - Indexing and searching for a big record should work (that's what the
   unit tests do).
 - Test an index scan search (on the staff interface):
    Search > More options > Check "Scan indexes".
 - Enable 'itemBarcodeFallbackSearch' and try to circulate any word, it
   shouldn't break.
 - Searching for a biblio in a new subscription shouldn't break.
 - Running bulkmarcimport.pl shouldn't break.
 - And so on... for the rest of the .pl files.

[2] a record that cannot be parsed by MARC::Record is simply skipped (bug 10684)
