[8u] RFR 8241888: Mirror jdk.security.allowNonCaAnchor system property with a security one

[Martin Balao]

Hi,

I'd like to request a review for the 8u backport of 8241888 [1]. For
further information on why it's desirable to have this in JDK-8, have a
look at the 8u-CSR [2] (already approved).

Webrev.00:

http://cr.openjdk.java.net/~mbalao/webrevs/8241888/8241888.webrev.jdk8u.jdk.00/

Main line patch does not apply cleanly because we need to propagate
java.security change across all java.security-os files. There is nothing
OS-specific in 8241888 so this change applies to all of them.

Testing:

 * Tests in sun/security/validator passed.
 * Executed my own internal test to make sure that both the Security
property and the replacement of the System property work fine
  * Note: no new tests have been proposed as part of the main line patch
because it's a trivial change and SecurityProperties functionality
(basis for this patch) is already covered by tests.

Thanks,
Martin.-
