RFR: 8155039: Simplify code to setup SSLContextImpl and TrustManagerFactoryImpl

[Claes Redestad]

After some internal discussions:

http://cr.openjdk.java.net/~redestad/8155039/webrev.03/

Drops the PropertiesWrapper and Properties-retrieving approach in favor of a getter to retrieve multiple properties into a Map<String, String>.

Claes' first iteration of the fix changed this to use a GetPropertyAction.privilegedGetProperties method that returned a Properties object. I expressed a concern that this was now exposing an object that, if accidentally leaked to untrusted code could cause much more damage than the original code (since the code would be able to set/get/remove *any* system property). Hence the current fix which uses a wrapper class which is not exported.
