These are now defined to return != SYS_ARCH_TIMEOUT on success rather than the time
waiting. The returned times were unused by lwip and this simplifies at
least some implementations.

This is to allow an implementation to use a nesting counter, or a
recursive mutex. Also clarify that the value returned by
sys_arch_protect() is opaque to lwip and implementation dependent.

This fixes a bug where when writing IP_PKTINFO to msg_control, the
msg_controllen field was not updated with the length written
This bug is exposed by applications that provide a msg_control buffer large
enough for multiple control messages. Then when calling CMSG_NXTHDR, it
returned a next cmsg pointer even though was no additional message
The ip6_addr_t structure may have an addition slot so is not necessarily
the size of an ipv6 address, so some uses of sizeof(ip6_addr_t) were not
correct.

No need to have additional if statement for PBUF_REF/PBUF_ROM.
It can be merged to the existing swtich(type) cases.

Adds partial support for selective acknowledgements (RFC 2018).
This change makes lwIP negotiate SACK support, and include SACK
data in outgoing empty ACK packets. It does not include it
in outgoing packets with data payload.
It also does not add support for handling incoming SACKs.

Use vj_uncompress_err() instead of duplicating the same code.

Current code does not correctly update ifoutoctets counter because nb->tot_len
is always 0. Fix it by setting nb->tot_len to actual payload length so we can
update ifoutoctets correctly.

This changes tcpflags_t to be a u16_t for all cases. The TCP Appropriate
Byte Count support added a new flag that used a bit past 8 and since this
flag is now required, tcpflags_t can no longer be a u8_t
This does not increase the size of struct tcp_pcb due to padding that
already existed (see bug #51326 for details)
