* Get current error reporting level.
* PHP 4.1.2 does not return current error reporting level in ini_get (php 5.1b3 and
* 4.3.10 does). Retrieve current error reporting level while setting error reporting
* to ini value and reset it to retrieved value.
* Check error_reporting value before logging error.
* Don't log errors that are disabled by @ (error_reporting = 0). Some SquirrelMail scripts
* (sq_mb_list_encodings(), ldap function calls in functions/abook_ldap_server.php)
* handle errors themselves and @ is used to disable generic php error messages.
