#1044140, #1044032, #1056174 by KarenS and bfroehle, lots of fixes to tests to avoid exception errors and make it more flexible.

#781088 Reorganize Content Migrate files for efficiency, and also to make it easier to use the individual module code as examples on how to implement the hooks.

#781088 by Island Usurper, loganfsmyth, and mattbatt, fixes to get imagefield and filefield data migrated.

Rewrote content_migrate to migrate one data record at a time, with a drupal_alter() before inserting it into the new table, to allow fields like imagefields to re-organize the data in the new table.

Add more information to the drupal_alter -- field info when altering an instance and instance info when altering a field -- for settings that are being moved from field to instance or vice versa. Initial attempt to handle the imagefield migration.

Add installation function to content migrate that will swap the stored content_extra_weight values to the new field_bundle_settings variable. Also properly set the body weight, which is otherwise not right.

#781088 More work on content migrate. Fix allowed values to make them into arrays, to match the new way that lists are stored.

node_reference and user_reference field types now live in the 'references' project - http://drupal.org/project/references

Kudos @swentel and @stalski for moving the code forward and taking over maintainance

still requires core fix in

- #470470 by neilnz, use iLIKE for postgres selects.
- #558420 Accept trimmed titles in nodereference autocomplete validation to prevent title mismatch errors when title ends with space.
- security fixes in http://drupal.org/cvs?commit=380008 (SA : http://drupal.org/node/829566)

Revert #780566 by stella, add drupal_alter() for content_allowed_values lists created by userreference and nodereference, needs more thought.

Also need to re-name the autocomplete module to the new node_reference and user_reference module names.

More tweaking of content migrate script, starting to work correctly for at least the cases I have tested so far.

Adding content migrate module. Still needs lots of work, just getting this much committed so it is not lost.

Fix fatal errors when enabling cck and fieldgroup by removing install schema. Add entity_type to cck table.

#699066 by litwol and chx : add meta data to the 'referenceable nodes / users' queries for easier tracking
