core: Added void to declarations of functions with empty argument list

In C language, a declaration in the form int f(); is equivalent to int f(...);, thus being able to accept an indefinit number of parameters. With the -Wstrict-prototypes GCC options, these declarations are reported as "function declaration isn’t a prototype".
On some cases, this may trick the compiler into generating unoptimized code (like preparing to handle variadic argument list).
In all cases having a declaration int f() and a definition inf f(int) is missleading, even if standard compliant.
This is still Work in Progress. (maybe adding the -Wstrict-prototypes option to default is desireable)

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

core/tcp/tls: added tls_max_connections global parameter

- set a limit to active tls connections
- its management is done in tcp code, as tls is encryption layer over
tcp
- tls connections are still counted as tcp connections, thus this limit
cannot exceed tcp_max_connections
- default value 2048
- core.tcp_options lists also the tls connections number

(tcp alias_flags and new_conn_alias_flags).

tcp: config option for the async write block size

- the block size used for the async writes can now be configured
both from ser.cfg (tcp_wq_blk_size) and at runtime. This value
has only a little performance impact and only when writes are
delayed. Small values are safer (big values on proxies that
open thousands of connections over slow links would eat up a
lot of memory). For now it's main use is debugging.

tcp: use dynamic config framework, part 2

- added tcp_connect_timeout, tcp_send_timeout,
tcp_connection_lifetime, tcp_max_connections, tcp_accept_aliases
to the config framework.

new_conn_alias_flags

- tcp add alias policy changes (experimental): now new aliases are added even if matching aliases for different connections exists. Until now an existing alias pointing to some other connection would trigger an error, the reason being that someone could try to "steal" a connection. However this turned out to affect also normal usage, like UAs behind nats that change the ip, or rebooted UAs (that didn't have a chance to close the tcp connection).

- applied patch from Dragos Vingarzan <vingarzan@fokus.fraunhofer.de> which moves all the forking part into 2 functions in pt.c (fork_process and fork_tcp_process). - added PROC_NOCHLDINIT rank value for Dragos's fork_process (if this value is used as child_id/rank_value the mod_child functions will not be called) - added register_procs(processes_no), used from mod_init when a module knows that it will fork some children (replaces the old process_count++ / the patch's estimated_process_count++) - added get_max_procs(): returns the maximum (estimated) number of processes
