lwiperf: remove the comments that this is IPv4 only

IPv6 works (tested against iperf version 2.0.9 on linux)

lwiperf: make tradeoff client mode work

fix compiling with LWIP_NOASSERT defined

See bug #54157

lwiperf: fix unused function warning/error

lwiperf: implemented "dual" client mode

lwiperf: start implementing iperf client

Only the transmission side works for now (todo: dual and tradeoff mode).
Also, only a 10 second timeout mode is implemented for now.

lwiperf: enable TCP over IPv6 connections

tested against iperf 2.0.10
redefine LWIPERF_SERVER_IP_TYPE if you don't want both IP versions

lwiperf: fix testing against iperf 2.0.10 (bug #52901)

lwiperf: fix double-free of pbufs on recv error

Work on task #14780: Add debug helper asserts to ensure threading/locking requirements are met

Add LWIP_ASSERT_CORE_LOCKED() to several more places

Fix bug #52189: list add and remove bug in <lwiperf.c>
Apply patch from xuyao hong

Reformat lwiperf.c using astylerc

Even more pbuf_header -> pbuf_add/remove_header replacements (also in strings)

task #14597: cleanup pbuf_header usages (use pbuf_add_header/pbuf_remove_header instead)

make tcp apps depend on LWIP_CALLBACK_API, too

Fix bug #49827: wrong cast to size_t on 16-bit x86 architecture
I hope I caught all of them.
TODO: Same for casts to get rid of alignment warnings, these are also casts via size_t

lwiperf: Simplify #if LWIPERF_CHECK_RX_DATA guard

The variable i is equal to q->len after exit the for loop.
Check the received data should not change the logic of update packet_idx.
So let's simplify the code a bit.

Fix compile when IPv4 is disabled

Cleanup hton*/ntoh* function handling and platform abstraction
Let lwip use functions/macros prefixed by lwip_ internally to avoid naming clashes with external #includes.
Remove over-complicated #define handling in def.h
Make functions easier to override in cc.h. The following is sufficient now (no more LWIP_PLATFORM_BYTESWAP):
#define lwip_htons(x) <your_htons>
#define lwip_htonl(x) <your_htonl>

Implement consistent IPx_ADDR_ANYx macro naming between IPv4 and IPv6
- rename IP4_ADDR_ANY to IP4_ADDR_ANY4
- IP4_ADDR_ANY (= IP_ADDR_ANY) is now IPv4 any address in ip_addr_t format

Minor: memcpy -> MEMCPY / SMEMCPY

Fix a few incorrect uses of err_t. Found by converting lwip error codes to an enum, but I'm not sure wether I want to commit the actual enum conversion.

lwiperf: improved documentation, removed unused enum members

Documentation review with Simon, minor changes

minor: coding style fixes

doxygen updates - include IPv6 in documentation. Exclude include/netif/ppp/polarssl.
Convert TODO -> @todo

minor whitespace change only

Simon says: dual-stack does not work on iperf because there IPs encoded in the payloads and IPv6 is not supported there in the current lwIP implementation -> revert

Compile fix lwiperf.c after my last change

Implement dual-stack in lwiperf, netbiosns and sntp

Fix netconn access after it was freed in lwiperf - found by Coverity

lwiperf: TX buffer can be static

Add iperf to apps;
Fix compile of lwiperf.c

removed spaces at line ending, fixed include guard

lwiperf: fixed const-cast warning

Added lwiperf, a simple ipv4/tcp iperf peer
