We should allow for 63 characters TLDs, according to RFC 1035, instead of arbitrary 10.

https://en.wikipedia.org/wiki/Domain_Name_System#cite_ref-rfc1034_1-2

As far as minimum length of 2 is acceptable, becuse IANA says that it isn't likely to introduce 1 character TLD, maximium length is too short.

This partially resolves #9485

Adding comment to clarify logic refs https://github.com/piwik/piwik/issues/8128#issuecomment-121523583

For performance reasons

As preparation for Common::hash() changing its hash function some time in future

As preparation for introduction of a stronger hash function in https://github.com/piwik/piwik/issues/5728, this standardizes the usage of the current **password** hash function across the Login and UsersManager plugins. Specifically:

* Use UsersManager::getPasswordHash() throughout, instead of previous direct use of md5() in some places

* Concentrate the hash length sanity check in the newly created UsersManager::checkPasswordHash(). Previously, UsersManager\Auth and Login\PasswordResetter classes did it separately. Both checks were moved into the newly created UsersManager class function, as that is also where other public static password check functions reside.

* Replaced the "md5" string with "hash" in affected variable names and comments

No functional change is intended.
