These tests could adopt the dynamically sized buffers used for the
packet-pressure tests, however throughput is not an important feature
of these tests.
Printing out dropped packets caused significantly more overhead in the
parallel tests due to increased noise on the network. This noise would
push the tests past their provided timeouts.
Dynamic buffers gives the network stack the maximum throughput while
still supporting smaller devices. This should expose the largest number
of issues across differently sized platforms.
Additionally, restructured the UDP tests to avoid unintentionally flooding
the recieving side with bad data after failed packets.
Also, added a bit more documentation
A larger buffer gives the network stack the best options for maximizing
throughput. However, the initial buffer size did not fit on small
targets. Resized 8192 -> 1024.
Added test for the pattern of packets used during the DTLS
handshake. This pattern (5x ~300 byte packets) has been very
problematic for new network interfaces.
Attempt to maximize the devices bandwidth with an exponentially growing
transaction of random sequences. Also prints the time taken and bandwidth
reached during the tests.
A few new error codes are added to nsapi_error_t and
support for non-blocking socket connect is added.
Nanostack's connect call will be non-blocking.
Whereas LWIP connect call is currently blocking, and it could be changed now
to be non-blocking.
1. Add targets into build_travis.py and tests.py.
2. Add target SPI pins into SPI SD test samples.
3. Rename target TOOLCHAIN_GCC_ARM/retarget.c to avoid name collision of compiled retarget.o with platform/retargets.cpp.

During open, the socket checked the internal stack variable,
assuming it would alway be null on a socket not connected to
the network. However, when a socket is closed, the stack variable
was not updated, causing the socket to incorrectly return a
parameter error if reopened.
The simple fix was to set the stack to null on close. A non-null
stack is a predicate for a non-null socket variable, so no additional
checks are needed in socket functions.
It's currently possible to generate a socket event when a non-blocking socket is closed:
1. _pending is set to 0 in https://github.com/ARMmbed/mbed-os/blob/master/features/netsocket/TCPSocket.cpp#L22
when the socket is created.
2. close() calls event() in https://github.com/ARMmbed/mbed-os/blob/master/features/netsocket/Socket.cpp#L66
3. event() increments _pending, and since _pending is 1 it will call _callback() in https://github.com/ARMmbed/mbed-os/blob/master/features/netsocket/TCPSocket.cpp#L167
However, if send() (for example) is called, this can happen:
- send() is called and sets _pending to 0.
- when the data is sent, event() is called, which sets _pending to 1 and calls _callback().
- if close() is called at this point, there won't be an event generated for close() anymore,
since _pending will be set to 2.
Same thing for recv. Also, same thing for TCPServer and UDPSocket.
This PR changes the initial value of _pending to 1 instead of 0, so that
events are never generated for close().

mbed compile doesn't support two different FEATURE_X folders being merged, so we'll have to move our nanostack driver into the Nanostack folder for the time being.
The configuration option for the mbed TLS specific hardware acceleration
has to be in the macro section and not in the device capabilities
section in targets.json.
The option has also been renamed to better reflect its function.
The crypto hardware acceleration might require defining a lot of mbed
TLS specific macros. Enumerating all of them in `targets.json` creates
too much noise, therefore we move it into a target specific mbed TLS
header.
The target with crypto hardware acceleration has to
- indicate its capability in `targets.json` by adding "CRYPTO"
to the "device_has" section
- has to define his crypto hardware acceleration related macros
in an `mbedtls_device.h` header
- place the `mbedtls_device.h` file in the
`features/mbedtls/targets/TARGET_XXXX`
directory specific to the target
This is to allow other types of PHY drivers than just RF.
Mesh-API does not actually care about driver type, it is drivers
responsibility to register right handlers with Nanostack.
* Implement a wrapper class NanostackRfPhy to ensure backward
compatibility.
* Remove mesh_connect()/disconnect() functions from MeshInterface
This job is already done in inherited classes.
* LoWPANNDInterface and ThreadInterface should only be used with
NanostackRfPhy.
* Move all the functionality to LoWPANNDInterface and
ThreadInterface classes.
* AbstractMesh class modified to be pure virtual
* Thread/6LoWPAN specific functionality totally separated.
Now linker will drop the unreferenced classes.
* MeshInterfaceNanostack now inherits from AbstractMesh
The cbmaster_done function is a callback which will be called from
the asynch I2C interrupt handler. Calling to printf from this context
sometimes lead to missing interrupts on the slave side. This was at least
encountered on STM32F3 MCUs.
Initially these assertions were added to protected simultaneous
send/recv from the same socket when similarly purposed mutexes were
removed.
However, simultaneous send/recv can still be useful for UDP if the
payload is guaranteed to be less than the MTU across the entire
connection.
