Each proxied connection uses eight file descriptors: the accepted and the outgoing socket, a duplicate of each, and a pipe for each direction. With the default soft RLIMIT_NOFILE of 1024, setting up forwarding fails with "Too many open files" at about 127 concurrent connections, well before the default --connections-max=256, and the connection is closed right after being accepted. socket-proxyd's I/O is sd-event based and handles fds above 1023, so it does not need the select()-compatible soft limit. Call rlimit_nofile_bump(-1) at startup to raise RLIMIT_NOFILE as far as permitted, like udevd does. (cherry picked from commit 98752540be47778e253cbafe51c7ccdd30f4995e)
