console-server: refactor pollfd management

Instead of the previous memory management of pollfd array,
with a fixed and flexible part and hardcoded indices,
provide two functions to request and release pollfds.

- console_server_request_pollfd
- console_server_release_pollfd

The pollfds are still in the same array but can be requested and
released by these functions now. struct console_server and
struct console now contain indices into that array of pollfds.

The benefit of this contribution is that the new interface provides a
clean allocator-like abstraction for requesting and releasing pollfds,
which will scale to multiple consoles and can be refactored or
unit-tested more easily in the future.

The previous implementation was tightly coupled to the single-console
use-case and the pollfds stored at hardcoded indices.
