clashes with a portal already registered by another mod, e.g. if the size
and frame node is not unique.
A false return value should be handled, you could:
* Fall back to using a secondary material for portals to be built with.
* Use error() to exit lua with a message explaining how two mods are
clashing and how it can be resolved.
* Continue without a portal (the reason will be logged for the user).

* Continue without a portal (the reason will be logged for the user).
* `nether.unregister_portal(name)`
* Unregisters the portal from the engine, and deletes the entry with key
`name` from `nether.registered_portals` and associated internal tables.
* Returns true on success
* register_portal_ignition_item(name, ignition_failure_sound)
* You will probably never need to call this, it exists only for completeness.
* `nether.register_portal_ignition_item(name, ignition_failure_sound)`
* ignition_failure_sound is optional, it plays any time an attempt to use
the item occurs if a portal is not ignited.
* `nether.register_wormhole_node(name, nodedef_overrides)`
* Can be used to register wormhole nodes with a different post_effect_color
from the "nether:portal" node. "Post effect color" is the tint the world
takes on when you are standing inside a portal. `post_effect_color` is the
only key/value that is needed in the nodedef_overrides table to achieve that,
but the function allows any nodedef key/value to be specified/overridden.
* Invokes `minetest.register_node()`, so can only be called at mod load time.
* After `register_wormhole_node()`, invoke `register_portal()` and include
`wormhole_node_name` in the portal_definition, assigning it the name of the
new wormhole node.
