3eaf976152 tcp: fix cwnd rollover introduced by ABC 
Changes for TCP Appropriate Byte Counting introduce a potential cwnd
rollover by not taking into account integer promotion on tcpwnd_size_t
during inequality comparisions

This fixes the issue by introducing a macro TCP_WND_INC which detects
the rollover correctly and now holds the tcpwnd_size_t at the maximum
value rather than not incrementing the window.  This provides a slight
performance improvement by allowing full use of the tcpwnd_size_t number
space for the congestion window

84502e5ae0 etharp.c: Ensure etharp_query() allocates adequate pbuf if copying/consolidating. 
etharp_query() queues packets, instead of sending, if a relevant arp-request is
pending.

Code walks the packet (a pbuf chain) to determine whether any pbufs are marked
'volatile': If so, we cannot simply enqueue the packet, and instead allocate a
new pbuf from RAM, copying the original packet, and enqueueing this new pbuf.

The bug here is that the allocation refers to the tot_len field of a temp pbuf*,
'p', instead of the head, 'q'.

In the case where the first pbuf of the chain is non-volatile but the second pbuf
*is* volatile, then we'll request an allocation that uses the tot_len field of
the second pbuf. If the first pbuf is non-zero length, the allocated pbuf (chain)
will be too small to allow the copy.

c03fef9a3c bug #50837: add zero-window probe timeout 
This commit adds a timeout to the zero-window probing (persist timer)
mechanism. LwIP has not historically had a timeout for the persist
timer, leading to unbounded blocking if connection drops during the
zero-window condition

This commit also adds two units test, one to check the RTO timeout
and a second to check the zero-window probe timeout

de90d03e48 tcp: task #14128 - Appropriate Byte Counting support 
This commit adds TCP Appropriate Byte Counting (ABC) support based on
RFC 3465

ABC replaces the previous congestion window growth mechanism and has been
configured with limit of 2 SMSS.  See task #14128 for discussion on
defaults, but the goal is to mitigate the performance impact of delayed
ACKs on congestion window growth

This commit also introduces a mechanism to track when the stack is
undergoing a period following an RTO where data is being retransmitted.

Lastly, this adds a unit test to verify RTO period tracking and some
basic ABC cwnd checking

8e83e206f4 sockets.c: Make sock_inc_used overflow check robust. 
Before this patch, it was possible that the overflow check might
miss an overflow event.

e.g. Consider 2 threads, both executing this method. u8_t fd_used is on 255...

Thread A -> atomically increment fd_used (which is now 0)
Thread B -> atomically increment fd_used (which is now 1)
Thread A -> check overflow... sees everything ok
Thread B -> check overflow... sees everything ok

And the overflow is missed :(

c722261142 tcp: bug #50614: move unsent queue check/pcb->snd_buf update 
This commit corrects what looks like an ancient incorrect organization
of the logic for processing an ACK which acks new data.  Once moved,
we can also change to using TCP_SEQ_LEQ on ackno instead of TCP_BETWEEN
because ackno has already been checked against snd_nxt

The work of checking the unsent queue and updating pcb->snd_buf (both
steps required for new data ACK) should be located under the conditional
that checks TCP_SEQ_BETWEEN(ackno, pcb->lastack+1, pcb->snd_nxt)

The comment following the unsent queue check/pcb->snd_buf update even
indicates "End of ACK for new data processing" when the logic is clearly
outside of this check

From what I can tell, this mis-organization isn't causing any incorrect
behavior since the unsent queue checked that ackno was between start of
segment and snd_nxt and recv_acked would be 0 during pcb->snd_buf update.
Instead this is waisted work for duplicate ACKS (can be common) and other
old ACKs

751ee7a534 SNTP: Implement round-trip delay compensation 
Introduce a new configuration define SNTP_COMP_ROUNDTRIP to compensate
for network round-trip delays when setting the system clock from SNTP.
Note that this feature requires compiler support for 64-bit arithmetic.

cc77b308a4 SNTP: Unify timestamp extraction from response packet 
Avoid piecemeal invocation of pbuf_copy_partial() for each SNTP header
field. The new code may sometimes copy more than necessary, but the
complexity is reduced.

2fa9cd8530 SNTP: Streamline timestamp handling 
Generalize the NTP timestamp conversion arithmetic, and provide hooks
for using native NTP timestamps when setting or getting the system
clock time. Convert microseconds to a fraction as needed when getting
the system time.

e8e247f22e 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.
