[patch] CoAP's ReadResource interface has too narrow data-length type

[GoogleCodeExporter]

The ReadResource interface used by CoAP resources specifies its data length 
using a uint8_t. Given that some responses may very well be >255 bytes in size 
(some of ours are), a uint8_t is not sufficient.

The attached patch switches this over to a size_t instead. Surprisingly there 
were only two locations which needed updating - most uses already passed the 
value from a sizeof() operation anyway.
