Add "application layered TCP connection API (altcp)"
...
altcp is an abstraction layer that prevents applications linking against the
tcp.h functions but provides the same functionality. It is used to e.g. add
SSL/TLS or proxy-connect support to an application written for the tcp callback
API without that application knowing the protocol details.
Applications written against the altcp API are directly linked against the
tcp callback API for LWIP_ALTCP==0, but then cannot use layered protocols.

tcp: do not keep sending SYNs when getting ACKs
...
If a locally generated TCP SYN packet is replied to with an ACK
packet, lwIP immediately sends a RST packet followed by resending the
SYN packet. This is expected, but on loopback interfaces the resent
SYN packet may immediately get another ACK reply, typically when the
other endpoint is in TIME_WAIT state (which ignores the RSTs). The
result is an endless loop of SYN, ACK, RST packets.
This patch applies the normal SYN retransmission limit in this
scenario, such that the endless loop is limited to a brief storm.

bug #50476 : initialize ssthresh to TCP_SND_BUF
...
This commit changes ssthresh to be the largest effective congestion
window (amount of in-flight data). This follows the guidance of RFC
5681 which recommends setting ssthresh arbitrarily high.
LwIP was previously using the receive window value at the end of the
3-way handshake and in the case of an active open where the receiver
used window scaling and/or window auto-tuning, this resulted in a very
small ssthresh value even though the window ramped up once the connection
was established

arp/ndp: allow overriding the decision to copy pbufs
...
lwIP aims to support zero-copy TX, and thus, must internally handle
all cases that pbufs are referenced rather than copied upon low-level
output. However, in the current situation, the arp/ndp packet queuing
routines conservatively copy entire packets, even when unnecessary in
cases where lwIP is used in a zero-copy compliant manner. This patch
moves the decision whether to copy into a centralized macro, allowing
zero-copy compliant applications to override the macro to avoid the
unnecessary copies. The macro defaults to the safe behavior, though.
