kohabug 2076: updated 2.2 -> 3.0 upgrade

Numerous changes to update22to30.pl to help ensure
that a database upgraded from 2.2.9 to 3.0 will have
a DB schema identical to that of a new installation.

These changes were testing by starting from an empty database,
loading koha.mysql from the 2.2.9 package, then running

update22to30.pl
move_marc_to_authheader.pl
move_marc_to_biblioitems.pl
dropping the following tables:
  marc_subfield_table
  auth_subfield_table
  marc_biblio
  marc_blob_subfield
  auth_word
  biblioanalysis
  borexp
  catalogueentry
  charges
  itemsprices
  marc_word
  marcrecorddone
  sessionqueries

  users
