[sr-dev] statistics in libkcore

Hi! While testing my pipelimit patch I got tons of these messages on my poor Mac: 2(32754) ERROR: <core> [statistics.c:385]: get_used_waiting_queue(): Could not open /proc/net/tcp. kamailioMsgQueueDepth and its related alarms will not be available. 2(32754) ERROR: <core> [statistics.c:385]: get_used_waiting_queue(): Could not open /proc/net/udp. kamailioMsgQueueDepth and its related alarms will not be available. 2(32754) ERROR: <core> [statistics.c:385]: get_used_waiting_queue(): Could not open /proc/net/tcp. kamailioMsgQueueDepth and its related alarms will not be available. 2(32754) ERROR: <core> [statistics.c:385]: get_used_waiting_queue(): Could not open /proc/net/tcp. kamailioMsgQueueDepth and its related alarms will not be available. 2(32754) ERROR: <core> [statistics.c:385]: get_used_waiting_queue(): Could not open /proc/net/udp. kamailioMsgQueueDepth and its related alarms will not be available. Would it be ok to disable this whole function and return 0 if we're not on a Linux system? I think about using #ifdef / #endif /O
