Janusz Kaczmarek 70bb6fe0ae Bug 18458: Fix subfields ordering when Merging authority records
While doing a merge, if a subfield(s) precedes the controlled subfields
(like $i before $a in 7XX, which comes before $a -- rare but will
become more and more usual) after merging will be moved to the end.
This is not right.

The patch (with AuthorityMergeMode == loose) make merge consider the
subfields order: all subfields which originally were found before
the first controlled subfield (e.g. $i before $a in 7XX / MARC 21)
will remain in the front, the rest of not controlled subfields that
should remain in the field will come after the subfields copied
from authority rec.

As a bonus, $9 will be placed at the end.

To test:
0) Have AuthorityMergeMode == loose;
1) Have some field in bibliorecord, controlled by an authority, with
extra subfield(s) (i.e. not present in authority rec.) placed at the
beginning of the field;
2) Open (not necessarily edit) and save the connected authority;
3) See that the extra subfieds were moved to the end of the field
   (and $9 is in the front);
4) Apply the patch;
5) Reorder subfields in biblio field;
6) Open (not necessarily edit) and save the connected authority;
7) See that the order has been conserved, additionally $9 the last
   subfield in the field.

Amended:
Moved field creation to its original place. Changed $9 handling. Simplified the following add_subfields for loop. Edited comments.
Restored the append_fields_ordered call (see comment6).

With this patch, the Merge.t test now passes.

Merge biblios linked to authority $mergefrom (mandatory parameter).
If $mergeto equals mergefrom, the linked biblio field is updated.
If $mergeto is different, the biblio field will be linked to $mergeto.
If $mergeto is missing, the biblio field is deleted.
MARCfrom is used to determine if a cleared subfield in the authority record
should be removed from a biblio. MARCto is used to populate the biblio
record with the updated values; if you do not pass it, the biblio field
will be deleted (same as missing mergeto).
Normally all biblio records linked to $mergefrom, will be considered. But
you can pass specific numbers via the biblionumbers parameter.
The parameter override_limit is used by the cron job to force larger
postponed merges.
Note: Although $mergefrom and $mergeto will normally be of the same
authority type, merge also supports moving to another authority type.
