In step_init_3() we try to apply provided or calculated earlier haproxy maxsock and memmax limits. Let's encapsulate these code blocks in dedicated functions: apply_nofile_limit() and apply_memory_limit() and let's move them into limits.c. Limits.c gathers now all the logic for calculating and setting system limits in dependency of the provided configuration.
