curl_escape() returns a pointer to a C-string. When one is done with the C-string, one must curl_free() the pointer. (See http://curl.haxx.se/libcurl/c/curl_escape.html .) To be able to call curl_free on the pointer, we must keep it in the first place.

Also, a cpp file in which curl functions are called should include <curl/curl.h> directly, even if it already gets included indirectly, i.e. via other includes. So adding that, too.


Note that curl_escape() is deprecated and should be replaced by curl_easy_escape(). This change does not do that, as this should probably be done for all occurrences at once and be accompanied by some refactoring.
