1. 7.4 components/file.inc \webform_file_allow_access()

Pre-render callback to allow access to uploaded files.

Files that have not yet been saved into a submission must be accessible to the user who uploaded it, but no one else. After the submission is saved, access is granted through the file_usage table. Before then, we use a $_SESSION value to record a user's upload.
