Details:

In Linux, when using the system's sockets headers, struct msghdr->msg_iovlen
is not defined as int.
  - POSIX[1] says it must be int
  - My solution was:
    - add a typedef int msg_iovlen_t; in lwip's sockets.h
    - declare msg_iovlen as msg_iovlen_t inside struct msghdr in lwip's
sockets.h
    - let the user typedef msg_iovlen_t as the type they need for their
system
    - Line 253: declare i as msg_iovlen_t i;
