/* This file is concerned pretty entirely, as you see from its name, with
logging in and out members, and the validation of that.  It contains:

void Login()
- shows a page for the user to type in their username and password.
- caches the referring URL in $_SESSION[&#39;login_url&#39;].
- uses the Login template and language file with the login sub
  template.
- if you are using a wireless device, uses the protocol_login sub
  template in the Wireless template.
- accessed from ?action=login.

void Login2()
- actually logs you in and checks that login was successful.
- employs protection against a specific IP or user trying to brute
  force a login to an account.
- on error, uses the same templates Login() uses.
- upgrades password encryption on login, if necessary.
- after successful login, redirects you to $_SESSION[&#39;login_url&#39;].
- accessed from ?action=login2, by forms.

void Logout(bool internal = false)
- logs the current user out of their account.
- requires that the session hash is sent as well, to prevent automatic
  logouts by images or javascript.
- doesn&#39;t check the session if internal is true.
- redirects back to $_SESSION[&#39;logout_url&#39;], if it exists.
- accessed via ?action=logout;session_var=...

string md5_hmac(string data, string key)
- old style SMF 1.0.x/YaBB SE 1.5.x hashing.
- returns the HMAC MD5 of data with key.

string phpBB3_password_check(string passwd, string passwd_hash)
- custom encryption for phpBB3 based passwords.

void validatePasswordFlood(id_member, password_flood_value = false, was_correct = false)
- this function helps protect against brute force attacks on a member&#39;s password.
