function content_load in Content Construction Kit (CCK) 5

1. 6.3 content.module \content_load()
2. 6 content.module \content_load()
3. 6.2 content.module \content_load()

Load data for a node type's fields.

When loading one of the content.module nodes, we need to let each field handle its own loading. This can make for a number of queries in some cases, so we cache the loaded object structure and invalidate it during the update process.
