* Adds SIGNAL_HANDLER and SIGNAL_HANDLER_DOES_SLEEP to prevent signal callbacks from blocking (#52761)
Adds SIGNAL_HANDLER, a macro that sets SHOULD_NOT_SLEEP(TRUE). This should ideally be required on all new signal callbacks.
Adds BLOCKING_SIGNAL_HANDLER, a macro that does nothing except symbolize "this is an older signal that didn't necessitate a code rewrite". It should not be allowed for new work.
This comes from discussion around #52735, which yields by calling input, and (though it sets the return type beforehand) will not properly return the flag to prevent attack from slapping.
To fix 60% of the yielding cases, WrapAdminProcCall no longer waits for another admin's proc call to finish. I'm not an admin, so I don't know how many behinds this has saved, but if this is problematic for admins I can just make it so that it lets you do it anyway. I'm not sure what the point of this babysitting was anyway.
Requested by @optimumtact.

admin: Calling a proc while another admin is calling one will no longer wait for the first to finish. You will simply just have to call it again.

add: Spraying holy water on tiles will now prevent cult-based teleportation from using them as a destination point.
tweak: Quantum, wormhole and magic teleportation is no longer disrupted by bags of holding.
/cl
Refactors some teleportation code so it uses do_teleport instead of directly forceMove.
do_teleport now has a channel argument, to specify the type of teleportation used. This will affect what can and cannot interfere with teleportation. For example, BoHs interfere with bluespace teleportation but not wormhole, quantum or magic teleportation.
do_teleport now sends a COMSIG_ATOM_INTERCEPT_TELEPORT signal, allowing the target turf (or anything placing a signal on said turf) to react appropriately. As a proof of concept, blessed tiles use it to prevent teleportation from the cult channel.
Intercepting teleportation can have interesting potential uses, from teleport denial fields, to teleport scramblers (teleports you somewhere else instead), telefraggers that gib anyone unlucky enough to teleport in their area of effect, teleport anchors that shunt all teleportations in a wide area to themselves, and so on.
