* port_fwd: Better parameterise procfs_scan_listen()David Gibson2023-11-071-31/+24
| | | | | | | | | | | | | procfs_scan_listen() does some slightly clunky logic to deduce the fd it wants to use, the path it wants to open and the state it's looking for based on parameters for protocol, IP version and whether we're in the namespace. However, the caller already has to make choices based on similar parameters so it can just pass in the things that procfs_scan_listen() needs directly.

* port_fwd: Move automatic port forwarding code to port_fwd.[ch]David Gibson2023-11-071-0/+179
The implementation of scanning /proc files to do automatic port forwarding is a bit awkwardly split between procfs_scan_listen() in util.c, get_bound_ports() and related functions in conf.c and the initial setup code in conf(). Consolidate all of this into port_fwd.h, which already has some related definitions, and a new port_fwd.c.
