server: Add utility functions for setting CLOEXEC and NONBLOCK
Upcoming patches will be setting FD_CLOEXEC and/or O_NONBLOCK on more
files; the correct way to do this requires a read-modify-write, which
is enough lines of code to be worth a helper function. I chose the
semantics of close()ing the fd on (unlikely) failure, on the grounds
that these functions will likely be used only immediately after the fd
is created.
