Bulletproof CredentialStorage state handling

Browse Source 
As noted by the class javadoc, CredentialStorage has seen the number
of cases to cope with grow. This change tries to address those cases.

	src/com/android/settings/CredentialStorage.java

Added ChooseLockSettingsHelper.EXTRA_KEY_PASSWORD to coordinate
additional producer and consumer.

    constant declaration here, since its used by callers of
    ChooseLockSettingsHelper.launchConfirmationActivity
	src/com/android/settings/ChooseLockSettingsHelper.java

    old producer
	src/com/android/settings/ConfirmLockPassword.java
    new producer (CredentialStorage wants passwords and patterns)
	src/com/android/settings/ConfirmLockPattern.java
    new consumer
	src/com/android/settings/CredentialStorage.java
    old consumer
	src/com/android/settings/CryptKeeperSettings.java

Made class final and removed protected from method to make it clear
ChooseLockSettingsHelper is not to be used by subclassing.

	src/com/android/settings/ChooseLockSettingsHelper.java
