This is a major cleanup of the authentication code. I've simplified a bit so that the auth code never deals with setting project cookies. Other than that the code should function exactly as before.

• core/authentication_api.php: total cleanup

• account_update.php: rename auth_api functions

• index.php: rework to use new auth_api functions

• login.php: rework to use new auth_api functions

• login_select_proj_page.php: rename auth_api function

• logout_page.php: use auth_clear_cookies()

• manage_user_reset.php: rename auth_api functions

• core/user_api.php
  (user_create): rename auth_api functions
  (user_signup):

  • tweak LDAP code and add a note to look at it in more detail
  • rename auth_api functions
    (user_get_row_by_name): use === instead of ==
