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

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.
