* Add warning when dropping inclusion inherent

* improve warning when dropping inclusion inherent

- use the actual runtime `warn!` macro
- do not speculate about why the error occurred
- show the actual error returned

* BROKEN: add note if the current block matches the session start block

This doesn't compile for a variety of reasons; this commit demonstrates
what the issues are. I don't think this is an essential feature, so I'm
stopping work on it here instead of pushing through it.

* Revert "BROKEN: add note if the current block matches the session start block"

This reverts commit eeb79ab7.

* ensure a runtime logger exists before attempting to log a warning to it

* More doc fixes.

* Minor refactorings in the process of #2177

By having everything peer set related depend directly on the enum the
code becomes more clear and it is also straight forward to add more
peersets/protocols as the compiler will complain if you forget to
implement parts of it.

* Add peer set infos on startup properly

For feature real_overseer.

+ Fixes from review. Thanks @coriolinus and @ordian

!

* More structure in network-bridge

Some changes, which would have helped me in groking the code faster.

Entry points/public types more to the top. Factored out implementation
in their own files, to clear up the top-level view.

* Get rid of local ProtocolName type definition.

Does not add much at this level.

* Fix tests + import cleanup.

* Make spaces tabs.

* Clarify what correct parameters to send_message are

* Be more less vague in docs of send_message.

* Apply suggestions from code review

Extend copyright on new files to 2021 as well.

* 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

Closes #2241
