Russ Butler 90cd978785 Separate interface from stack in NSAPI 
This patch consists of:
-Add NetworkInterface to wrap objects bound to a stack and update
    socket code to handle this in addition to NetworkStacks
-Update MeshInterface to inherit from NetworkInterface
-Update NanostackInterface so it only inherits from NetworkStack
-Add MeshInterfaceNanostack and update LoWPANNDInterface and
    ThreadInterface to inherit from this

Christopher Haster a6edc268f3 Coalesce redundant events to reduce cpu usage in lazy implementations 
*cough* esp8266 *cough*

this is especially important for event-loop based systems where
excessive events results in problematic memory consumption.

Russ Butler 8f33c0fc4f Add synchronization to the network socket API 
Add mutexes to protect the network socket API.  Also use semaphores to
wait for read/write events.  Also fix a typo in the comments for
timeout.

Christopher Haster 943dd711a9 Added WFI to save power in temporary polling implementation 2016-07-21 18:19:21 -05:00
Christopher Haster f2715b7e77 Consolidate set_timeout/set_blocking behaviour 
- Avoids ambiguity when both are used
- Matches Python behaviour

Christopher Haster fc71badb69 Rename Interface -> Stack 
NetworkInterface  -> NetworkStack
EthernetInterface -> EthernetStack
WiFiInterface     -> WiFiStack
CellularInterface -> CellularStack
MeshInterface     -> MeshStack

Christopher Haster 0ae11b49e8 Removed is_connected function 
- Not supported by TCP/UDP protocols
- Uncommon and less useful with proper error handling

Christopher Haster 56e11d6709 Added better support for SocketAddress/string addresses/ports 2016-07-21 18:19:21 -05:00
Christopher Haster dfc1ca4cef Move to single state-change interrupt 
Pros
- Easier to implement
- More similar to SIGIO in BDS sockets

Cons
- Less information, but this information had a high risk of being
  faulty/spurious

Christopher Haster d38ccb70a6 Add open call as alternative to passing NetworkInterface at construction 
Pros
- Allows memory to be statically allocated
- Avoids issues with Thread creation before entering main
- Matches existing APIs such as FunctionPointer and Ticker

Cons
- Does not enforce passing a NetworkInterface

Christopher Haster 4c7992cb24 Matched changes NetworkSocketAPI 
Responded to feedback from mbed-client implementation
to introduce a full feature set that should support most
of the use cases for the API.
