CVE-2013-4496:samr: Remove ChangePasswordUser

This old password change mechanism does not provide the plaintext to
validate against password complexity, and it is not used by modern
clients.  It also has quite difficult semantics to handle regarding
password lockout.

The missing features in both implementations (by design) were:

 - the password complexity checks (no plaintext)
 - the minimum password length (no plaintext)

Additionally, the source3 version did not check:

 - the minimum password age
 - pdb_get_pass_can_change() which checks the security
   descriptor for the 'user cannot change password' setting.
 - the password history
 - the output of the 'passwd program' if 'unix passwd sync = yes'.

Finally, the mechanism was almost useless, as it was incorrectly
only made available to administrative users with permission
to reset the password.  It is removed here so that it is not
mistakenly reinstated in the future.

CVE-2013-4496:Revert remainder of ce895609b04380bfc41e4f8fddc84bd2f9324340

Part of this was removed when ChangePasswordUser was unimplemented,
but remove the remainder of this flawed commit.  Fully check the
password first, as extract_pw_from_buffer() already does a partial
check of the password because it needs a correct old password to
correctly decrypt the length.
