Ticket 47753 - Add switch to disable pre-hashed password checking

By default, 389 DS doesn't allow pre-hashed passwords to be set by
anyone other than Directory Manager. This privilege can be delegated
to other users by adding them to the Password Administrators group.
This works fine for most cases, but there are cases where one might
want to allow anyone to set pre-hashed passwords. An example is the
FreeIPA project, who has their own SLAPI plug-in that controls
pre-hashed password checking. We should add a switch to completely
disable pre-hashed password checking to support this case.

Ticket #346 - Fixing memory leaks

Description:
There was a leak in attrlist_replace/attrlist_replace_with_flags
when attr_replace failed to replace the attribute values.

commit 708a56b8d524131362e2d71b7fbc2eb257075e14 for Ticket #47834
tried to fix it, but it was wrong and introduced a double free.
This patch fixes it so that ...
If attr_replace fails and if to be replaced Slapi_Attr is newly
created in attrlist_replace//attrlist_replace_with_flags, the
Slapi_Attr is removed from the attrlist (alist) and Slapi_Attr
is freed.  Otherwise, values and Slapi_Attr are not freed since
Slapi_Attr is just pointing the attribute in the attrlist and
values are consumed in attr_replace.
