41a36098b3 tcp: Fix TCP timestamps for big-endian systems
Current parsing code is building reverse-order integer, and then calls htonl()
to assign right value to "ts_recent" field of pcb.

This works correctly on little-endian machines, where htonl() reverses bytes.
However, on big-endian machines, htonl() is no-op, so bytes stay reversed.

This patch fixes it by building non-reversed integer.

e7ab7e0773 autoip: Choose next address after rate limit
AutoIP now selects a new address after rate limit timeout,
AutoIP tries a new address by incrementing the tried_llipaddr counter
in the ACD_DECLINE case of the callback.

In lwIP pre-2.2.0, address conflict detection was handled within autoip.c, and
the incrementing happened in autoip_restart() (line 150). When ACD was
extracted into a separate module in 2.2.0, this increment was missing for the
rate-limiting path.

Without this change, devices continuously retry the same IP address after rate
limiting, causing them to fail Bonjour Conformance Tests.

b1edb7780f tftp: bind to TFTP port only when in server mode
The TFTP app should not bind to the TFTP server port when configured as
a client. Instead, the local port should be chosen from the dynamic
range (49152 ~ 65535) so that if the application is stopped and started
again, the remote server will not consider the new packets as part of
the same context (which would cause an error since a new RRQ would be
unexpected).

e799c266fa makefsdata: extend file type matching with .shtml and .shtm
[Problem]
When using makefsdata perl script to convert shtml files with SSI tags
the shtml files get generated with text/plain content type, making
browsers not render them correctly

[Solution]
Extend the regex to generate text/html content type for any of:
.htm, .html, .shtm, .shtml extensions

574bd6e5aa tcp_in : fix ooseq update error
if a pbuf received with the same seqno in ooseq ,
we then check  the size and replace the existing one
with the larger one,but if the existing one is the
last segment in ooseq ,it might has been trimed before.
the replacing action will overrun our receive windows

Allow one to provide a custom implementation of free/malloc/calloc
instead of the lwip internal allocator. The code to use the libc's
implementation already existed, so generalize the existing code and make
the libc variant a specialized case of this new capability, retaining
full backwards compatibility.
