[feature] Enable CoAP resources to access URI query information

[GoogleCodeExporter]

Currently TinyOS CoAP resources have no way of getting access to any request 
components such as URI query parameters (e.g. when called with GET 
/resource?foo=bar). In essence this limits CoAP resources to be fixed 
resources, which is, well, rather limiting.

The attached patch extends the ReadResource interface used by the CoAP 
resources to also be passed a coap_uri_t object, from which things such a query 
parameters and network authority can be obtained, and this in turn can then be 
used by the resource to alter its behavior accordingly. In our case for 
example, we need this to be able to request particular sensor samples by their 
sequence number.

Note that this patch also updates the handling of CoAP query options to match 
the later drafts - each key-value pair is now expected in its own query option, 
rather than ampersand (&) delimited in a single query option the early drafts 
specified.
