785b7aba3c Sockets: Unit tests and apps corrections
* Include lwip/inet.h in some unit tests and apps
  * Since they use htons() and pals.
* test/unit/api/test_sockets.c:
  * write() could be declared by external socket headers
    * Call lwip_write() instead.
  * Code expects fcntl() to return 6
    * But O_RDWR could have another value if external
      socket headers are present
    * Replace 6 by O_RDWR.
* apps/tftp/tftp.c:
  * recv() could be declared by external socket headers
    * Rename it to tftp_recv()

f92d6702bc Sockets: declare msghdr->msg_iovlen as msg_iovlen_t
* Lwip declares msghdr->msg_iovlen as int, but when
  using external socket headers, some systems declare
  msg_iovlen as size_t or others.
* This patch creates a new type msg_iovlen_t and
  expects users to typedef it to the type they need
  for their system.

b1b6275110 socket/netconn recv: FIN should only be reported once
FIN should only be reported once (as '0' for sockets, as 'ERR_CLSD' for
netconns). Before this change, ERR_CLSD was returned forever...

This is the 2nd try. First try (commit ebcae98ae6)
was buggy in that it could drop the FIN if it was read together with data
(reverted in commit ebcae98ae6).

This version fixes this by adding an apiflag and a netconn flag to keep
track of this.

f5c37c8cbb Fix broken MSG_PEEK on TCP sockets (post-2.0.3 bug)
MSG_PEEK on TCP sockets was broken since commit b71d4477ea
from 06.03.2017: recv hung in an endless loop and tcp_recved() was called for peeked data
(which would result in a too large window advertised).

Aded TCP MSG_PEEK to socket unit tests

3a01c32e55 test_sockets: fix pointer to integer conversion
This fixes a pointer to integer conversion in test_sockets_msgapi_cmsg()

This was identified by Travis CI: https://travis-ci.org/yarrick/lwip-merged/builds/225640702

2f117add7a sockets: task #14247, add CMSG and IP_PKTINFO
This commit adds CMSG infrastructure (currently used with recvmsg) and
the IP_PKTINFO socket option.

In order to use IP_PKTINFO, set LWIP_NETBUF_RECVINFO to 1

Unit test is added to verify this feature

557a11047d Patch #9307: Replace mem_malloc+memset with mem_calloc
Aside from reducing source code, on systems which use MEM_LIBC_MALLOC,
this has the potential to improve performance depending on the underlying
memory allocator

See http://stackoverflow.com/questions/2688466/why-mallocmemset-is-slower-than-calloc

81e4726607 test_socket: conditional compile buffer trailer code
This code is marked as dead when BUF_SZ is a multiple of 4 (current
situation with unit tests)

This hopefully fixes a -Wunreachable-code failure found by Travis CI

0a5a18e703 test_socket: add sendmsg/recvmsg TCP test
This migrates the sendmsg TCP test from socket examples (task #14408)
to socket unit tests

Additionally, this adds support for testing recvmsg, creating a TCP
test for both sendmsg/recvmsg (referred to as msgapi test)

This also makes a small change to msgapi UDP to clear the receive
buffer after verifying the previous datagram

4c78ec7931 test_socket: replace {0} with memset
Using {0} broke Travis CI even though this should be correct for
initializing struct msghdr (see example in Linxu man pages:
http://man7.org/linux/man-pages/man3/cmsg.3.html)

Just use memset for now which is the common approach in LwIP codebase

02e957de1e test_socket: convert sendmsg test to use recvmsg
This converts the sendmsg test to use recvmsg for receiving, thus
exercising both sendmsg and recvmsg in a single test

This also adjusts the test naming to communicate all message APIs
(sendmsg/recvmsg) are being tested

53fcd50870 task #14408: move sendmsg UDP to unit tests
This commit moves the sendmsg UDP test from socket examples to socket
unit tests

The test has been converted to send/receive on the loopback interface
and also test a connected sendmsg with NULL msg_name
