Merge mainstream 'master' branch into refactoring

During merge I had to revert:
	Nikita's patch for php_splice() (it probably needs to be applyed again)
	Bob Weinand's patches related to constant expression handling (we need to review them carefully)
	I also reverted all our attempts to support sapi/phpdbg (we didn't test it anyway)
