"udp bind" and "udp send" commands use the same net context
variable and they fail early if the context is already used.
This prevents from using "udp send" after "udp bind", which
makes the commands hard to use for testing bidirectional
communication. Make "udp send" reuse the already bound
context if possible, and resort to allocating temporary one
otherwise.

In case packet read fails for any reason, there's no point proceeding or
printing the byte, just break the loop in such case.

As the common.h is only meant to be used by the network
shell files, rename it to be more descriptive in order to
avoid possible conflicts with any other common.h file.
