Log Message:
-----------
[pmc] Clarify dead coroutines
Coros are not resumable when all yield states are exhausted.
This is consistent with the LUA design, which we follow, and all other
coro implementations I know of. Just the parrot book argues that after a
return the state should be automatically reset. Technically no problem, even
without the quirks described in
https://github.com/parrot/parrot/issues/564#issuecomment-3503597
or via a seperate reset() method, but semantically an auto-reset is problematic.
Added testcases for all the relevant tickets: #564, #585 and there is on
bug remaining: TT #1003 leading to Null PMC access in get_string on a dead coro
