- Fixed doc in pdp.xsd on PDP extensions

- fixed javadoc

datatype implementation classes to authzforce-ce-core-pdp-api

policies/resquests/responses (still pointing to XACML 2.0 XSD)
- Added test extensions for result filter (for CombinedDecision from
XACML Multiple Decision Profile, in TestCombinedDecisionResultFilter),
simple datatype (dnsName-value from XACML DLP/BAC profile, in
TestDNSNameValueEqualFunction class), complex datatype (XACML Policy, in
class TestXACMLPolicyAttributeValue), function (dnsName-value-equal from
XACML DLP/NAC profile, in TestDNSNameValueEqualFunction class),
combining algorithm from XACML Additional Combining Algorithms Profile
(in class TestOnPermitApplySecondCombiningAlg)
- Fixed NullPointerException occuring when specifying unsupported
combining algorithm in PDP configuration
- New method in PdpExtensionLoader to get list of extensions of a given
type
- Fixed bug in PdpExtensionLoader considering input extension type
invalid if no extension found of this type (although type is correct)
- Renamed DNSNameValue to DNSNameWithPortRangeValue class to distinguish
dnsName datatype from new dnsname-value type in XACML DLP/NAC profile
with accepts just a port number (not a range)
- Removed support for dnsName-equal and ipAddress-equal functions which
do not exist in XACML spec actually (the regexp-match equivalent is to
be used instead)
