give password plugin drivers more power

Allow password drivers more control over the entire password changeing
processes not just the save action. Allow them to perform old/new
password comparisons and also password strength checking.

*) allow password drivers override default password comparisons (eg
   new is not same as current) #6473
*) allow password drivers override default strength checks (eg allow
   for 'not the same as last x passwords')
*) allow separate password saving and strength drivers for use of
   strength checking services eg HaveIBeenPwned.com #5040
*) allow drivers to define password strength rules displayed to the
   user
*) rename password_require_nonalpha config option to
   password_check_strength to reflect new strength checking
   possibilities (added backwards compatibility)

2.2. Password Strength Drivers
------------------------------
Password plugin supports many password strength checking mechanisms which are
handled by included drivers. Just pass driver name in 'password_strength_driver' option.
3. Driver API
-------------
Driver file (<driver_name>.php) must define rcube_<driver_name>_password class
with public save() method that has two arguments. First - current password, second - new password.
Driver file (<driver_name>.php) must define rcube_<driver_name>_password class. Drivers should
provide one or both of a public save() or check_strength() method.
All password changing drivers (used in config `password_driver` - the password driver) must have
a save() method. The same driver can also contain a check_strength() method or a separate driver
containing this method can be used in `password_strength_driver` (the strength driver). To enable
strength checks ensure `password_check_strength` is set to true.
The save() method, used for changing the password has two arguments:
First - current password, second - new password.
This method should return PASSWORD_SUCCESS on success or any of PASSWORD_CONNECT_ERROR,
PASSWORD_CRYPT_ERROR, PASSWORD_ERROR when driver was unable to change password.
Extended result (as a hash-array with 'message' and 'code' items) can be returned
too. See existing drivers in drivers/ directory for examples.
Optionally a password driver can contain a compare() method which has three arguments:
First - current password, second - test password, third - compare type.
Compare type: PASSWORD_COMPARE_CURRENT - when comparing the test password with current password.
PASSWORD_COMPARE_NEW - when comparing the current password with the test password.
For PASSWORD_COMPARE_CURRENT it should return error text if user entered and real current password
DO NOT MATCH. For PASSWORD_COMPARE_NEW it should return error text if user entered and real current
password DO MATCH. Else it should return null (no error).
The check_strength() method, used for checking password strength has one argument: new password.
This method should return null on success or error message text on failure.
Optionally a strength driver can contain a strength_rules() method. This has no arguments as returns
a string, or array of strings explaining the password strength rules.
