Jon Shallow d0bfbb7ac8 client code: Make sure static variables are re-initialized if needed
For embedded applications that can call the 'main()' function multiple
times, they  need to have any statically (globally) defined variables
reset to their default values.

libcoap client example

This example shows how to configure a client to use libcoap

Fast configuration (Between RIOT instances):

Preparing the logical interfaces:

sudo ./../../dist/tools/tapsetup/tapsetup --create 2

Client invocation

For the client:

PORT=tap0 make term
coapc coap://[ip6-address]/some/path

The IP address to connect to needs to be that as returned by libcoap_server, or that of the tap0 interface, etc.

Handling the static memory allocation

libcoap for RIOT is using the sys/memarray module and therefore there are certain limits. Said resources are defined in libcoap/src/coap_mem.c, but can be overwritten at compile time.
