Some database changes for dealing with concurrent ID generation problems.
(SF bug #495059) - SQL file separated into database_schema.sql, for creating the schema, clean-database.sql, which removes tables, views etc. from an existing DSpace database, and update-sequences.sql which resets the ID generators, but is only used after an SQL dump which sets explicit primary keys. - Sequences for primary key generation added to SQL schema - SQL function "getnextid" added as an abstraction for access to those sequences - Database manager now uses getnextid() SQL function to get IDs - this means other DB backends can hide ID generation specifics behind this - Minor tweak to HistoryManager, which was accessing DB manager's in-memory ID generator directly - now it doesn't do this. - Old, now unnecessary "reset ID generator" admin servlet/JSP removed git-svn-id: http://scm.dspace.org/svn/repo/trunk@362 9c30dcfa-912a-0410-8fc2-9e0234be79fd
