[views] Display attributes in entity creation form based on "add" permission
Previously, the "update" permission was used. Hence in case the latter is
more restrictive that the "add" permission, an user may not be able to set
such an attribute, despite she may have "add" permission on it.
As a result of the change of permissions action in `editable_attributes`
method (add/update depending on whether the entity is being created or
modified), the "eid" attribute would have shown up in the edition form. To
avoid this, it is moved in the "hidden" section (where it should arguably
belong anyways).
Closes #4342844.

"""md5crypt.py - Provides interoperable MD5-based crypt() function
SYNOPSIS
import md5crypt.py
cryptedpassword = md5crypt.md5crypt(password, salt);
DESCRIPTION
unix_md5_crypt() provides a crypt()-compatible interface to the
rather new MD5-based crypt() function found in modern operating systems.
It's based on the implementation found on FreeBSD 2.2.[56]-RELEASE and
contains the following license in it:
