Details:

Hello guys,

i'd like to ask if it would be possible to initialize all static/global
variables inside xxx_init() functions instead of bank on linked start-up
code. 

For example one critical i found in sockets.c:

void
lwip_socket_init(void)
{
  socksem   = sys_sem_new(1);
  selectsem = sys_sem_new(1);
---->  memset( sockets, 0, sizeof( sockets ) ); <----- please add this line
}

(The compiler i use (TI Code Composer) doesn't initialize some static and
global variables correctly. Without this hack sockets[] array is not
initialized to zeroes and so i'm not able open any socket )

Thank you very much,
Petr
