58de2af5f2 test/fuzz: add some applications, add an experimental multi-packet mode
The experimental multi-packet mode splits input bytes depending on a length
decoded from the first 2 bytes and does that until the end of input.
To use this mode, compile with "make D=-DLWIP_FUZZ_MULTI_PACKET"

7b6d2870ca test: add a unit test for TCP_CHECKSUM_ON_COPY with retransmissions
This triggers bug #50914 (TCP_CHECKSUM_ON_COPY when adding data to
retransmission) when data is added to an already transmitted segment
with an uneven length of tcp data.

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.

50a5d85f45 tcp: handle segmentation oversize during segment split (bug #52676)
This fixes a bug in tcp_split_unsent_seg where oversized segments were not
handled during the split, leading to pcb->unsent_oversized and
useg->oversize_left getting out of sync with the split segment

This would result in over-writing the pbuf if another call to tcp_write()
happened after the split, but before the remainder of the split was sent in
tcp_output

Now pcb->unsent_oversized is explicitly cleared (because the remainder at
the tail is never oversized) and useg->oversized_left is cleared after it is
trimmed

This also updates the test_tcp_persist_split unit test to explicitly check for
this case

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

1147b9ce38 test_dhcp: set link up on net_test netif
DHCP test code didn't set link up on net_test netif (exposed by changes
in 637bce91b4)

Then during the test_dhcp function, a Gratuitous ARP was not sent during
the call to dhcp_bind() because the link was still down

The sets the link state for all DHCP test functions

de531131c5 Fix compiler warnings seen with clang 8.1.0 on MacOS
This fixes the following warnings:

test_tcp.c:266:5: error: code will never be executed [-Werror,-Wunreachable-code]
    pbuf_free(p);
    ^~~~~~~~~
 - The check API 'fail' aborts the test, thus pbuf_free(p) will never be executed

pbuf.c:783:111: error: format specifies type 'unsigned short' but the argument has type 'u8_t' (aka 'unsigned char') [-Werror,-Wformat]
      LWIP_DEBUGF( PBUF_DEBUG | LWIP_DBG_TRACE, ("pbuf_free: %p has ref %"U16_F", ending here.\n", (void *)p, ref));
      ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~^~~~
 - LWIP_PBUF_REF_T is u8_t by default and doesn't match U16_F, so cast to u16_t. The cast and formatter will need to be changed
   if ref is larger than 16 bits

ethernet.c:105:16: error: format specifies type 'unsigned char' but the argument has type 'unsigned int' [-Werror,-Wformat]
               (unsigned)ethhdr->dest.addr[0], (unsigned)ethhdr->dest.addr[1], (unsigned)ethhdr->dest.addr[2],
~~~~~~~~~~~~~~~^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
 - addr[] is type u8_t, formatter is X8_F which should be 8 bits. 'unsigned' is an int, so cast to unsighed char instead

f582c88339 tcp: persist timer re-work (bug #50837)
This re-works the persist timer to have the following behavior:

  1) Only start persist timer when a buffered segment doesn't fit within
     the current window and there is no in-fligh data.  Previously, the
     persist timer was always started when the window went to zero even
     if there was no buffered data (since timer was managed in receive
     pathway rather than transmit pathway)
  2) Upon first fire of persist timer, fill the remaining window if
     non-zero by splitting the unsent segment.  If split segment is sent,
     persist timer is stopped, RTO timer is now ensuring reliable window
     updates
  3) If window is already zero when persist timer fires, send 1 byte probe
  4) Persist timer and zero window probe should only be active when the
     following are true:
       * no in-flight data (pcb->unacked == NULL)
       * when there is buffered data (pcb->unsent != NULL)
       * when pcb->unsent->len > pcb->snd_wnd
