Ignore PHP warnings removed when the @ operator is being used.

Please, consider applying this patch. It makes no sense to log PHP notices when the programmer has decided to avoid them by using the @ operator. This is specially important when using functions such as fsockopen because warnings are always generated. The only option for the programmer is the @ operator.

Otherwise, drupal administrators will get confused by records in their logs the mean nothing.

Patch attached.

hmm... actually, the site administrator is allowed to choose what to do with PHP errors (error_level option in admin/settings).

What about adding another option to let them choose what to do with PHP warnings removed by the @ operator?

The error_handler could look like this:

function error_handler($errno, $message, $filename, $line) {
  if (IGNORE_AT_SIGN_REMOVED_WARNINGS && error_reporting() == 0) {
    return;
  }

  ...
  ...
  ...

Where IGNORE_AT_SIGN_REMOVED_WARNINGS could be a constant defined as soon as the bootstrap process allows to use the variable_get() function.
