[PATCH 1/3] mpr: Implement remembered connection enumeration.

[Pierre Schweitzer]

Hi,

Please find attached a patch that implements enumerating remembered (aka
persistent) connections from registry.
Note that this leads to the removal of the null enumerator code which is
no longer used.

The next patches implement the creation and the deletion of persistent
connections.

As usual, this patch series got tested on ReactOS and its purpose is to
reduce the diff between Wine's MPR and ReactOS' one. The initial
implementation was too broken to get into Wine. This one is correct.

Cheers,
