frame allocs (25.2): @frame on a step list's field, @alloc_ok on a statement, and on an exported function

Browse source 
A field declared '@frame run: fn(...)' makes every function stored in it a frame root, as a System's
tick is. @alloc_ok("why") before a statement takes that statement out of frame_allocs and makes what
it allocates declared at run time; a function holding one keeps the fence's scope depth and puts it
back at its return, so a return inside the statement cannot leave the scope open. @alloc_ok above
'export function' was lost - export parses the declaration one call down - and is now carried to it.
