SecurityUtil: Generalize cert validation and AccessControlContext query; PropertyAccess: Fix security code, grant access to common 'trusted' properties

- SecurityUtil
  - Generalize cert validation for JAR and property access
  - Grant access to common AccessControlContext for 'same' cert

- PropertyAccess:
  - Fix security code: Passing the current AccessControlContext from the caller
    didn't include priviledges.

  - Grant access to common 'trusted' properties,
    which removes the need of passing the AccessControlContext for general properties
    like 'jnlp.', 'jogamp.' ..

  - Enable registering 'trusted' properties, when caller's cert is 'same'
