Consolidate the two separate timestamp Kconfig options into a single
CONFIG_NET_TIMESTAMP option that covers SO_TIMESTAMP, SO_TIMESTAMPNS
and SO_TIMESTAMPING socket options.
Previously CONFIG_NET_TIMESTAMPING was a separate option only used by
PKT sockets for hardware TX/RX timestamps and error queue support.
Since both options guard the same io_time field in iob_s and share
the s_options bitmask, merging them simplifies configuration without
functional impact.
Changes:
- Replace all CONFIG_NET_TIMESTAMPING with CONFIG_NET_TIMESTAMP in
pkt_input.c, pkt_recvmsg.c, pkt_sendmsg_buffered.c,
pkt_sendmsg_unbuffered.c, pkt_sockif.c, pkt_netpoll.c, pkt.h,
setsockopt.c, getsockopt.c
- Simplify iob.h conditional from OR of both to single option
- Remove NET_TIMESTAMPING Kconfig entry, update NET_TIMESTAMP
description to cover all three socket options

Add SO_TIMESTAMPING TX path for PKT sockets. Tagged TX
packets loop back through the driver with io_conn set,
are routed into conn->errahead, and delivered to userspace
via recvmsg(MSG_ERRQUEUE) with SO_TIMESTAMPING cmsg.
Add poll(POLLPRI) notification when errahead is non-empty.

Some third-party network libraries use PACKET_ADD_MEMBERSHIP to add MAC
addresses to devices, and this patch can add support for this.

Adds support for timestamping received UDP packets, either in
hardware or in kernel. Builds on the existing support of SO_TIMESTAMP
for SocketCAN.
Implementation uses CLOCK_REALTIME for timestamping to match the
behavior of Linux. This could be made configurable in future if needed.

1. Remove tcp_txdrain() from close() to avoid indefinitely block
2. Send TCP_RST immediately if linger timeout

rename the UDP_BINDTODEVICE to SO_BINDTODEVICE to follow the linux
style to be compatible with non-UDP protocol binding requirements

Implement si_send/sendto/recvfrom with si_sendmsg/recvmsg, instead of
the other way round.

Net cleanup (#17)
* Fix the semaphore usage issue found in tcp/udp
1. The count semaphore need disable priority inheritance
2. Loop again if net_lockedwait return -EINTR
3. Call nxsem_trywait to avoid the race condition
4. Call nxsem_post instead of sem_post
* Put the work notifier into free list to avoid the heap fragment in the long run. Since the allocation strategy is encapsulated internally, we can even refine the implementation later.
* Network stack shouldn't allocate memory in the poll implementation to avoid the heap fragment in the long run, other modification include:
1. Select MM_IOB automatically since ICMP[v6] socket can't work without the read ahead buffer
2. Remove the net lock since xxx_callback_free already do the same thing
3. TCP/UDP poll should work even the read ahead buffer isn't enabled at all
* Add NET_ prefix for UDP_NOTIFIER and TCP_NOTIFIER option to align with other UDP/TCP option convention
* Remove the unused _SF_[IDLE|ACCEPT|SEND|RECV|MASK] flags since there are code to set/clear these flags, but nobody check them.
Squashed commit of the following:
net/: Fix some naming inconsistencies, Fix final compilation issies.
net/inet/inet_close(): Now that we have logic to drain the buffered TX data, we can implement a proper lingering close.
net/inet,tcp,udp: Add functions to wait for write buffers to drain.
net/udp: Add support for notification when the UDP write buffer becomes empty.
net/tcp: Add support for notification when the TCP write buffer becomes empty.
Squashed commit of the following:
sched/sched/sched_getsockets.c: Fix an error in conditional compilation.
fs/: Remove all conditional logic based on CONFIG_NSOCKET_DESCRIPTORS == 0
Documentation/: Remove all references to CONFIG_NSOCKET_DESCRIPTORS == 0

tools/: Fixups for CONFIG_NSOCKET_DESCRIPTORS no longer used to disable sockets.
net/tcp: Add logic to send probes when SO_KEEPALIVE is enabled.
net/tcp: TCP socket should not have to be connected to configure KeepAlive.
net/: Add a separate configuration to enable/disable KEEPALIVE socket options.
net/tcp: Arguments to TCP keep-alive timing functions probably should be struct timeval as are the times for other time-related socket options.
net/tcp: Fix a backward conditional
net/tcp: Add some more checks and debug output to TCP-protocol socket options.
net/tcp: Cosmetic changes to some alignment.
net/: Adds socket options needed to manage TCP-keepalive and TCP state machine logic to detect if that the remote peer is alive. Still missing the timer poll logic to send the keep-alive probes and the state machine logic to respond to probes.
