Hardening/libcurl

**DON'T MERGE**

Orion uses libcurl to send HTTP requests.
The way it works is that it will *realloc* for whatever size it needs. So it is no use putting a larger value, say 200 bytes, since it will do a realloc if it needs more.

Also, this will happen everytime there is data to read from the socket, so it may happen many times
