ad824b4de1 Define copy/move ctors and assignment ops 
Delete special member functions where they are not used.
(as part of applying suggestions from cppcoreguidelines-special-member-functions)

These classes don't need to be copyable/movable:
  # copy/move not used:
  zmq:: TransportFactory, Socket, Message, UnmanagedRegion, Poller, Context
  shm:: TransportFactory, Socket, Message, UnmanagedRegion, Poller
  ofi:: TransportFactory, Socket, Message, Context
  shm:: ZMsg, Region, Monitor, TerminalConfig, Manager
  plugins:: Config, Control, TerminalConfig
  fairmq::StateQueue, StateMachine, ProgOptions, PluginServices, PluginManager, Plugin, Device, StateSubscription
  TestData, BadDevice, TestDevice (test suite heplers)

  # used via ptr interface:
  fairmq::UnmanagedRegion, TransportFactory, Socket, Poller, Message

These classes need to be movable/copyable:
 MyClass (test suite helper), fairmq::Channel, fairmq::Parts

1007de8e49 feat(ofi): Require asiofi 0.5 
* Modernize some ofi transport code along the way
  * Replace Boost.Container with `<memory_resource>`
  * Introduce namespaced headers
    * `<fairmq/Channel.h>`
    * `<fairmq/Message.h>`
    * `<fairmq/Poller.h>`
    * `<fairmq/Socket.h>`
    * `<fairmq/TransportFactory.h>`
    * `<fairmq/UnmanagedRegion.h>`
* Compile-firewall Boost.Process in `shmem::Manager` because it conflicts
with standalone asio
