MINOR: hlua: safe coroutine.create()
Overriding global coroutine.create() function in order to link the
newly created subroutine with the parent hlua ctx.
(hlua_gethlua() function from a subroutine will return hlua ctx from the
hlua ctx on which the coroutine.create() was performed, instead of NULL)
Doing so allows hlua_hook() function to support being called from
subroutines created using coroutine.create() within user lua scripts.
That is: the related subroutine will be immune to the forced-yield,
but it will still be checked against hlua timeouts. If the subroutine
fails to yield or finish before the timeout, the related lua handler will
be aborted (instead of going rogue unnoticed like it would be the case prior
to this commit)
