rootlessport: reduce memory usage of the process
Don't use reexec for the rootlessport process, instead make it a separate binary to reduce the memory usage. The problem with reexec is that it will import all packages that podman uses and therefore loads a lot of stuff into the heap. The rootlessport process however only needs the rootlesskit library. The memory usage is a concern since the rootlessport process will spawn two process per container which has ports forwarded. The processes stay until the container dies. On my laptop the current reexec version uses 47800 KB RSS. The new separate binary only uses 4540 KB RSS. This is more than a 90% improvement. The Makefile has been updated to compile the new binary and install it to the libexec directory. Fixes #10790 [NO TESTS NEEDED] Signed-off-by: Paul Holzinger <pholzing@redhat.com>
