http: fix the silent ignoring of proxy misconfiguraion
Earlier, the whole http.proxy option string was passed to curl without any preprocessing so curl could complain about the invalid proxy configuration. After the commit 372370f167 ("http: use credential API to handle proxy authentication", 2016-01-26), if the user specified an invalid HTTP proxy option in the configuration, then the option parsing silently fails and NULL will be passed to curl as a proxy. This forces curl to fall back to detecting the proxy configuration from the environment, causing the http.proxy option ignoring. Fix this issue by checking the proxy option parsing result. If parsing failed then print an error message and die. Such behaviour allows the user to quickly figure the proxy misconfiguration and correct it.
