Fix file path problems that are related to configured default folders.
The most visible affected bug that is fixed with this is path previews.

The {node_field_instance} table is very large ("mediumtext" in MySQL) so
it's absolutely no problem to store longer file extension specifications.

Mixed up "cvs commit" and "svn commit". Again, my sincerest apologies.

(make private downloads work by clearing the field's session variable)
and there wasn't a line missing but it was inserted at the wrong place,
for the 'delete' action instead of the 'insert' one.
So, add it for 'delete' ('insert' has it since the previous commit).

the database consistency patch, where it originally came from.

@tod0, test hook_filefield_file.

back porting imagefield preview handling updates. fixing some logic issues with single value uploads, and the
form theme functions. single value fields seem to be working. not sure about multivalue fields... required and
extension validation is still working. try at your own risk.

drupal_render.

filefield HEAD should be DRUPAL-5 compatible. I will branch for DRUPAL-5
once I've tested with DRUPAL-5 cck.
