Check for libcurl's return codes when appropriate.
Depending on the option being set by curl_easy_setopt, a return value different from CURL_OK can be returned (the same applies to curl_multi_* and CURLM_OK). This commit checks the return value from those calls and usually displays an error message with ERR() and returns -- in some cases, an error is shown but the function does not immediately return. A few lines of code have also been moved around in order to make returning from functions as harmless as possible. By: Raphael Kubo da Costa <kubo@profusion.mobi> SVN revision: 53275
