[8u] RFR 8200400: Allow Sasl mechanisms to be restricted

[Martin Balao]

Hi,

I'd like to request a review for the jdk8u backport of JDK-8200400 [1]:

 *
https://cr.openjdk.java.net/~mbalao/webrevs/8200400/8200400.webrev.jdk8u.jdk.00/

Changes:

 * Paths

 * java.security change per OS file

 * Sasl.java
  * copyright date
  * documentation hooks did not apply cleanly

 * Test
  * @module jtreg tag removed
  * @library path changed
  * Asserts import changed

Testing:

 * javax/security/sasl/Sasl/DisabledMechanisms.java passed

Thanks,
Martin.-
