5c5c08efcd network: simplify the timeout process logic
1.Consolidate absolute to relative timeout conversion into one place(_net_timedwait)
2.Drive the wait timeout logic by net_timedwait instead of devif_timer
This patch help us remove devif_timer(period tick) to save the power in the future.

6a3c2aded6 Fix wait loop and void cast (#24)
* Simplify EINTR/ECANCEL error handling

1. Add semaphore uninterruptible wait function
2 .Replace semaphore wait loop with a single uninterruptible wait
3. Replace all sem_xxx to nxsem_xxx

* Unify the void cast usage

1. Remove void cast for function because many place ignore the returned value witout cast
2. Replace void cast for variable with UNUSED macro

    Run all .h and .c files modified in last PR through nxstyle.

Author: Xiang Xiao <xiaoxiang@xiaomi.com>

    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.

66ef6d143a This commit adds an initial implemented of TCP delayed ACKs as specified in RFC 1122.
Squashed commit of the following:

    net/tmp:  Rename the unacked field of the tcp connection structure to tx_unacked.  Too confusing with the implementation of delayed RX ACKs.

    net/tcp:  Add delayed ACK configuration selection.  Rename tcp_ack() to tcp_synack().  It may or may not send a ACK.  It will always send SYN or SYN/ACK.

* sixlowpan: Fixes logic surrounding the Universal/Local bit. This bit represents whether the IID is locally/globally administered. The U/L bit is bit 1 of the MSB of the EUI-64. It should only be inverted in cases where there is a full EUI-64. In cases where the IID is derived from say, a short address, this bit should be forced to 0, indicating that it is locally administered.

22cd0d47fa This commit attempts remove some long standard confusion in naming and some actual problems that result from the naming confusion. The basic problem is the standard MTU does not include the size of the Ethernet header. For clarity, I changed the naming of most things called MTU to PKTSIZE. For example, CONFIG_NET_ETH_MTU is now CONFIG_NET_ETH_PKTSIZE.
This makes the user interface a little hostile.  People thing of an MTU of 1500 bytes, but the corresponding packet is really 1514 bytes (including the 14 byte Ethernet header).  A more friendly solution would configure the MTU (as before), but then derive the packet buffer size by adding the MAC header length.  Instead, we define the packet buffer size then derive the MTU.

The MTU is not common currency in networking.  On the wire, the only real issue is the MSS which is derived from MTU by subtracting the IP header and TCP header sizes (for the case of TCP).  Now it is derived for the PKTSIZE by subtracting the IP header, the TCP header, and the MAC header sizes.  So we should be all good and without the recurring 14 byte error in MTU's and MSS's.

Squashed commit of the following:

    Trivial update to fix some spacing issues.
    net/: Rename several macros containing _MTU to _PKTSIZE.
    net/: Rename CONFIG_NET_SLIP_MTU to CONFIG_NET_SLIP_PKTSIZE and similarly for CONFIG_NET_TUN_MTU.  These are not the MTU which does not include the size of the link layer header.  These are the full size of the packet buffer memory (minus any GUARD bytes).
    net/: Rename CONFIG_NET_6LOWPAN_MTU to CONFIG_NET_6LOWPAN_PKTSIZE and similarly for CONFIG_NET_TUN_MTU.  These are not the MTU which does not include the size of the link layer header.  These are the full size of the packet buffer memory (minus any GUARD bytes).
    net/: Rename CONFIG_NET_ETH_MTU to CONFIG_NET_ETH_PKTSIZE.  This is not the MTU which does not include the size of the link layer header.  This is the full size of the packet buffer memory (minus any GUARD bytes).
    net/: Rename the file d_mtu in the network driver structure to d_pktsize.  That value saved there is not the MTU.  The packetsize is the memory large enough to hold the maximum packet PLUS the size of the link layer header.  The MTU does not include the link layer header.

    Remove some dangling references to CONFIG_NET_TCP_RWND_CONTROL.
    net/tcp:  Take read-ahead throttling into account when calculating the TCP receive window size.
