Custom mg_set_non_blocking_mode() implementation

[dmitry-kandiner]

It would be nice to have an option for custom mg_set_non_blocking_mode() implementation - some architectures have non-standard way for doing so. For instance, Cyclone TCP stack implementation of fcntl() requires three parameters: a socket, a command and a pointer to the command parameters.

For the sake of record. SDK's version of fcntl() differs from the standard, and therefore the solution is to have a snippet in mongoose_custom.h to replace fcntl:

#include <core/bsd_socket.h>

#define F_SETFD 12345
#define FD_CLOEXEC 0

static inline int mg_fcntl(int fd, int cmd, ...) {
  if (cmd == F_GETFL) { uint32_t opt; fcntl(fd, cmd, &opt); return opt; }
  ...
}

#define fcntl mg_fcntl
