Detailed Description

Functions to check passwords against a policy requirement.

$policyVal is the value configured in $wgPasswordPolicy. If the return status is fatal, the user won't be allowed to login. If the status is not good but not fatal, the user will not be allowed to set the given password (on registration or password change), but can still log in after bypassing a warning.
