nsILoginManagerStorage in Firefox 3.0

 Store a new login.

 @param aLogin
        The login to be added.

 Search for logins matching the specified criteria, as with
 findLogins(). This interface only returns the number of matching
 logins (and not the logins themselves), which allows a caller to
 check for logins without causing the user to be prompted for a master
 password to decrypt the logins.

 @param aHostname
        The hostname to restrict searches to. Specify an empty string
        to match all hosts. A null value will not match any logins, and
        will thus always return a count of 0.
 @param aActionURL
        The URL to which a form login will be submitted. To match any
        form login, specify an empty string. To not match any form
        login, specify null.
 @param aHttpRealm
        The HTTP Realm for which the login applies. To match logins for
        any realm, specify an empty string. To not match logins for any
        realm, specify null.

 Search for logins matching the specified criteria. Called when looking
 for logins that might be applicable to a form or authentication request.

 @param count
        The number of elements in the array. JS callers can simply use
        the array's .length property, and supply an dummy object for
        this out param. For example: |findLogins({}, hostname, ...)|
 @param aHostname
        The hostname to restrict searches to, in URL format. For
        example: "http://www.site.com".
 @param aActionURL
        For form logins, this argument should be the URL to which the
        form will be submitted. For protocol logins, specify null.
 @param aHttpRealm
        For protocol logins, this argument should be the HTTP Realm
        for which the login applies. This is obtained from the
        WWW-Authenticate header. See RFC2617. For form logins,
        specify null.
 @param logins
        An array of nsILoginInfo objects. 

 NOTE: This can be called from JS as:
       var logins = pwmgr.findLogins({}, hostname, ...);

 Obtain a list of all hosts for which password saving is disabled.

 @param count
        The number of elements in the array. JS callers can simply use
        the array's .length property, and supply an dummy object for
        this out param. For example: |getAllDisabledHosts({})|
 @param hostnames
        An array of hostname strings, in origin URL format without a
        pathname. For example: "https://www.site.com".

 NOTE: This can be called from JS as:
       var logins = pwmgr.getAllDisabledHosts({});

 Fetch all logins in the login manager. An array is always returned;
 if there are no logins the array is empty.

 @param count
        The number of elements in the array. JS callers can simply use
        the array's .length property, and supply an dummy object for
        this out param. For example: |getAllLogins({})|
 @param logins
        An array of nsILoginInfo objects. 

 NOTE: This can be called from JS as:
       var logins = pwmgr.getAllLogins({});
       (|logins| is an array).

 Check to see if saving logins has been disabled for a host.

 @param aHost
        The hostname to check. This argument should be in the origin
        URL format, without a pathname. For example: "http://foo.com".

 Initialize the component. Not invoked automatically.

 Initialize the component, but override the default filename
 locations. This is primarily used to the unit tests and profile
 migration.

 @param aInputFile
        File to read for stored logins.
 @param aOutputFile
        If non-null, file to output logins to.

 Modify an existing login in the login manager.

 @param aLogin
        The login to be modified.

 Remove all stored logins.

 The browser sanitization feature allows the user to clear any stored
 passwords. This interface allows that to be done without getting each
 login first (which might require knowing the master password).

 Remove a login from the login manager.

 @param aLogin
        The login to be removed.

 Disable (or enable) storing logins for the specified host. When
 disabled, the login manager will not prompt to store logins for
 that host. Existing logins are not affected.

 @param aHost
        The hostname to set. This argument should be in the origin
        URL format, without a pathname. For example: "http://foo.com".
 @param isEnabled
        Specify if saving logins should be enabled (true) or
        disabled (false)
