Sebastien Lorquet fc7aa92b57 apps/netutils/libcurl4nx: This is an initial comit libcurl4nx. It is not complete yet, but I still wish to commit the unfinished bits to describe the roadmap, and because it is already usable. It will be updated and fixed in the future weeks and months, certainly including POST support and later, SSL.
Some improvements could be made by anyone.  For example, I know the main routine in perform() shall be split into several parts for readability. I apologize in advance for this kind of spaghetti code, but I was short on time to refactor it.  Also chunked HTTP transfer encoding would be a nice contribution from anyone interested. It is detected but not yet supported.
