Fix PKCS12 and BKS KeyStore as well as SSL renegotiation

Summary:
- Added KeyStoreTest and fixed PKCS and BKS keystores to be fully functional
- KeyStore and KeyStoreImpl improvements in libcore and bouncycastle for more RI-like behavior
- SSL Renegotiation fix for new implementation

Details:

external/bouncycastle

   TwoFish added back for BKS KeyStore. Like RC2, it not supported as
   a general cipher, but instead used internally for KeyStore
   implementation.

	src/main/java/org/bouncycastle/crypto/engines/TwofishEngine.java
	bouncycastle.config

    Added back PBEWITHSHAANDTWOFISH, PBEWITHSHAANDTWOFISH-CBC,
    PBEWITHSHA1ANDRC2-CBC, PBEWITHHMACSHA, PBEWITHHMACSHA1 to support
    PKCS12 and BKS KeyStore implementations (as determined by new
    KeyStoreTest)

	src/main/java/org/bouncycastle/jce/provider/BouncyCastleProvider.java
	src/main/java/org/bouncycastle/jce/provider/JCEBlockCipher.java
	src/main/java/org/bouncycastle/jce/provider/JCEMac.java
	src/main/java/org/bouncycastle/jce/provider/JCESecretKeyFactory.java

    Don't throw an error when deleting a non-existing KeyStore entry. The
    RI documentation (and behavior) says it throws an error when it fails
    to remove an entry, not when the entry does not exist.

    Try to make BC's PKCS KeyStore have a more RI-like getCreationDate behavior

	src/main/java/org/bouncycastle/jce/provider/JDKPKCS12KeyStore.java

    Make BC's PKCS KeyStore failfast on setting non-supported key,
    instead of failing later on get.

	src/main/java/org/bouncycastle/jce/provider/JDKPKCS12KeyStore.java

    Make BC's PKCS KeyStore handle setting a PrivateKey with an emtpy chain.

	src/main/java/org/bouncycastle/jce/provider/JDKPKCS12KeyStore.java

    Add more general avoidance of NullPointerExceptions on null aliases

    KeyStore improvements based on KeyStoreTest

    - Fix UnrecoverableKeyException to be a subclass of
      UnrecoverableEntryException, which was keeping the new
      KeyStoreTest from compiling.

	luni/src/main/java/java/security/UnrecoverableKeyException.java

    - Fix to not convert UnrecoverableKeyException to KeyStoreException,
      which was only being done because of the UnrecoverableKeyException
      superclass bug.

	luni/src/main/java/java/security/KeyStoreSpi.java

    - Harmony KeyStore was being overly aggresive about throwing on null
      alias arguments in cases where the RI was happy to pass them to the
      KeyStoreSpi.

	luni/src/main/java/java/security/KeyStore.java

    - New test after PKCS12 regresion. It enumerates and excercises
      all methods on all available KeyStore
      implementations. Unfortunately, the main varieties of KeyStores
      made this a lot more complicated than I was originally
      expecting. It does clarifiy the differences between the RI and
      BC KeyStore implementations, especially for PKCS12, where in
      some ways the RI is more feature complete (setting key via
      byte[]), but in other ways BC goes beyond some RI limitations
      (allowing storage of certificates).

	luni/src/test/java/java/security/KeyStoreTest.java

   TestKeyStore improvements while writing KeyStoreTest
   - Renamed "keyStorePassword" working usages to clarify if it really
     means the "storePassword" on the whole KeyStore, or if it is a
     "keyPassword" on individual keys.
   - Moved TestKeyStore from javax.net.ssl to java.security

    Fixing up SSL renegotiation support. Now that we are not trying to
    prevent renegotiation, make sure it is working correctly.

    - Remove SSL_VERIFY_CLIENT_ONCE to take the default behavior of
      re-requesting client certificate on renegotiation.

	luni/src/main/java/org/apache/harmony/xnet/provider/jsse/NativeCrypto.java
	luni/src/main/java/org/apache/harmony/xnet/provider/jsse/OpenSSLSocketImpl.java

    - Updated comments to reflect renegotiation. Bug fix to not clear
      out callback reference on handshake complete, since we need it for
      renegotiation.

   Updated for PKCS12 KeyStore support

   Added javadoc when writint KeyStoreTest
