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
* 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
