in theory, std::result_of_t should have been removed in C++20. and
std::invoke_result_t is available since C++17. thanks to libstdc++,
the tree is compiling. but we should not rely on this.
so, in this change, we replace all `std::result_of_t` with
`std::invoke_result_t`. actually, clang + libstdc++ is already warning
us like:

It's not possible to abort an RPC call entirely, since the remote part
continues running (if the message got out). Calling the provided abort
source does the following:
1. if the message is still in the outgoing queue, drop it,
2. resolve waiter callbacks exceptionally.
Using the word "cancellable" is more appropriate.
Also write a small comment at `send_message_cancellable`.
Make it consistent with the other 'send message' functions.
Simplify code generation logic in idl-compiler.
Interestingly this function is not used anywhere so I didn't have to fix
any call sites.
messaging_service.hh is a switchboard - it includes many things,
and many things include it. Therefore, changes in the things it
includes affect many translation units.
Reduce the dependencies by forward-declaring as much as possible.
This isn't pretty, but it reduces compile time and recompilations.
Other headers adjusted as needed so everything (including
`ninja dev-headers`) still compile.
Closes#10755
I want to be able to timeout `send_message`, but not through the
existing `send_message_timeout` API which forces me to use a particular
clock/duration/timepoint type. Introduce a more general
`send_message_abortable` API which gets an `abort_source&`, subscribes
to it, and uses the `rpc::cancellable` interface to cancel the RPC on
abort.
The function is 90% copy-pasta from `send_message{_timeout}`, only the
abort part is new.
Introduce a new header `message/rpc_protocol_impl.hh`, move here
the following things from `message/messaging_service.cc`:
* RPC protocol wrappers implementation
* Serialization thunks
* `register_handler` and `send_message*` functions
This code will be used later for IDL-generated RPC verbs
implementation.
