core: option to set number of workers per listen socket

- new cfg global parameter: socket_workers - set the number of worker
  processes for the next listen socket
- used before listen on udp and sctp socket - overwrites
  children/sctp_children value for that socket
- used bofer listen on tcp and tls socket - adds extra tcp workers,
  these handling traffic only on that socket
- socket_workers is reset with next listen socket that is added, thus
  use it for each listen socket where you want custom number of workers
- if this parameter is not used at all, it is the same behaviour as so
  far

Example for udp sockets:

children=4
socket_workers=2
listen=udp:127.0.0.1:5080
listen=udp:127.0.0.1:5070
listen=udp:127.0.0.1:5060

- it will start 2 workers to handle traffic on udp:127.0.0.1:5080 and 4
  for each of udp:127.0.0.1:5070 and udp:127.0.0.1:5060. In total there
  are 10 worker processes

Example for tcp sockets:

children=4
socket_workers=2
listen=tcp:127.0.0.1:5080
listen=tcp:127.0.0.1:5070
listen=tcp:127.0.0.1:5060

- it will start 2 workers to handle traffic on tcp:127.0.0.1:5080 and 4
  to handle traffic on both tcp:127.0.0.1:5070 and tcp:127.0.0.1:5060.
  In total there are 6 worker processes
