* incorporated most Objective-C 1 run time functions in objc1 from
packages/objcrtl/src/objcrtl10.pas (so that if {$modeswitch objectivec1}
is used, you don't have to include objcrtl anymore, because that unit
declares some identifiers with the same name as in objc1, such as id,
causing type clashes)
