Avoid duplicate of attachment by using a hash algorithm

Registered by Nicolas DS on 2009-08-10

Each time a file is uploaded, compute the hash of the file.

Check if the hash already exists in database:
yes => make a link
no => Store the hash, with file content.
It will avoid using disk space for nothing.

A hash algorithm like SHA-1, SHA-256 could be used.
