[PATCH 1/2] http.c: Use curl_multi_fdset to select on curl fds instead of just sleeping
Instead of sleeping unconditionally for a 50ms, when no data can be read
from the http connection(s), use curl_multi_fdset to obtain the actual
file descriptors of the open connections and use them in the select call.
This way, the 50ms sleep is interrupted when new data arrives.
