[BUG] [MEMLEAK] Memory leak in Phalcon\Debug::setCharset(), setLinesBeforeContext(), setLinesAfterContext()

[ghost]

Test case (will be similar for all functions):

$d = new \Phalcon\Debug();
$f1 = 1;
$f2 = $f1;
$d->setCharset($f2);

This happens because PHALCON_SEPARATE_PARAM_NMO() does not decrement the refcount when it separates the argument.
