Adds a new application which allows the registration of a uORB sensor (similar to faksensor) that publishes data received over a UDP socket to a uORB topic of the user's choosing. Implemented in userspace. Signed-off-by: Matteo Golin <matteo.golin@gmail.com>
Added a program which allows the user to stream uORB data from their selected topic over UDP in a form which can be interpreted by a netsensor device. Signed-off-by: Matteo Golin <matteo.golin@gmail.com>

@linguini1 not an issue, but normally structs and complex types are defined early inside a function, I think this is just a convention that Greg created, but in some cases it avoids misalignment, i.e. it you have an uint8_t followed by a struct definition. Maybe others here have a better explanation why this convention is used, since the C compiler don't care much about the variables position

Summary
Introduces a user-space
netsensor: a uORB sensor which publishes data receivedover UDP as a uORB topic.
A second application,
netsensor_stream, allows users to stream a uORB topic oftheir choosing over UDP. This can interface with a
netsensorinstance on adifferent device over the network.
Impact
This new sensor will allow users to conduct more complex testing using uORB.
Small network devices no longer need large CSV files containing simulated data
for
fakesensoruORB testing, but instead can receive this data piece-wise overthe network.
In addition, this opens the door to easy sensor network development with NuttX,
as sensors from other network nodes can be read from as regular uORB topics.
Testing
TBD, this is a draft.
