* Drive by fixes The visibility modifiers are remnants of the previous structure where HRMP wasn't a standalone module, by rather a submodule of the router module. * Add Currency assoc type to Config This would allow us to reserve balance for deposits. This commit also integrates the HRMP module in rococo, test-runtime and mocks to use the balances pallet. * Fix a bug that doesn't increment the age In case the request is not confirmed, the age would be incremented but not persisted. * Fix cleaning the indexes Before that change, the cleaning of the channel indexes was wrong, because it naively removed entire rows that was pertaining to the para we delete. This approach is flawed because it doesn't account for the rows that are pertaining to other paras that contain the outgoing one. This clearly violates the invariant imposed on the indexes, that all the index rows must contain alive paras, but apart from that it also lead to the situation where ingress index would contain the a different set of channels that an egress have. * Reserve currency for opening the channels Note the ugly `unique_saturated_into` calls. The reason for them is the currency trait accepts and defines the `Balance` associated type and the deposit values are coming from the `HostConfiguration` where they are defined using the `Balance`. I figured that parameterising `HostConfiguration` would be annoying. On the other hand, I don't expect these `unique_saturated_into` calls to give us problems since it seems to be a reasonable assumption that this module will be instantiated within a runtime where the Currency provided will have a Balance that matches the one used in the configuration. * Tests: Adapt `run_to_block` so that it submits a proper config * Tests: exercise the deposit logic
