[PATCH v2 0/3] Stronger typing for remote file i/o

[Tom Tromey <tromey@adacore.com>]

This short series adds stronger typing to the remote file i/o APIs, by
replacing some integers with enums.  This prevents mixing host and
remote-protocol values, and also differentiates between host and
remote file descriptors.

Regression tested on x86-64 Fedora 43.
