XMLRPCResponder constructor was missing.
This fixes the following crash signature:
VIEWER : 2012-12-12T14:25:13Z INFO("AppInit"): setStartupState: Startup state changing from STATE_LOGIN_NO_DATA_YET to STATE_LOGIN_DOWNLOADING

(gdb) bt
Reason was that if the server replied with some error code then
mResponse was undefined.
I also added code to retry three times in that case;
the http status code that I get was 503, which really
mean "Service *temporarily* unavailable", so a retry
is in order.
* Removed LLCurlRequest and replaced it's last usage with LLHTTPClient API calls.
* Deleted dead code.
* Renamed all the get4/post4/put4/getByteRange4 etc, back to their
original name without the '4'.
