/* @todo
* We have two ways of saving/loading states.
*
* First which is being used atm, just pure saving/loading of structures.
* The drawback is we have to deal with all the pointers around those structures,
* we'd have to update this code if we'd change state tracking.
* On the bright side it's fast, though it's not really needed as it's not that often operation.
* It could also worth to split those functions into appropriate parts,
* similar to the way context creation is being done.
*
* Second way would be to implement full dispatch api table and substitute diff_api during saving/loading.
* Then if we implement that api in a similar way to packer/unpacker with a change to store/load
* via provided pSSM handle instead of pack buffer,
* saving state could be done by simple diffing against empty "dummy" context.
* Restoring state in such case would look like unpacking commands from pSSM instead of network buffer.
* This would be slower (who cares) but most likely will not require any code changes to support in future.
* We will reduce amount of saved data as we'd save only changed state parts, but I doubt it'd be that much.
* It could be done for the first way as well, but requires tons of bit checks.
