XMLRPCResponder constructor was missing.
This fixes the following crash signature:

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.
The AIBufferedCurlEasyRequestEvents are not triggered unless
the derived class return true for needsHeaders().
That means, every class that implements received_HTTP_header(),
received_header() or completed_headers(), or implement
the virtual function completedHeaders(), or use the protected
member mReceivedHeaders directly.
This commits adds missing needsHeaders() for LLAvatarNameCache
(thanks Siana) and XMLRPCResponder. The former now uses
mReceivedHeaders directly instead of making a copy.
* Moved Responder stuff to LLHTTPClient.
* Renamed LLHTTPClient::Responder to LLHTTPClient::ResponderWithResult.
* Deleted LLHTTPClientAdapter and LLHTTPClientInterface.
* Renamed AICurlInterface::TransferInfo to AITransferInfo and moved it
to llhttpclient.h
* Removed 'CURLcode code' argument from completed_headers.
Renamed AICurlInterface::Responder to AICurlInterface::ResponderBase,
but without the virtual 'event' methods.
Derived from that: Responder and ReponderWithCompleted, where the
first defines result = 0, ErrorWithContent and error, and the latter
completedRaw and completed.
Added HttpClient::IgnoreBody, derived from Responder and implementing
'result' doing nothing; HttpClient::Ignore is now derived from
IgnoreBody and defines the still pure virtual getHTTPTimeoutPolicy.
Added ResponderBase::decode_body, which is now the sole place
where the code makes the decision wether some response data might be
LLSD or not based on the http status result. Before it just tried
to decode everything as LLSD, which seems a bit nonsense.
ResponderWithCompleted::completed no longer does anything, since
classes derived from ResponderWithCompleted are expected to override it,
or never call it by overriding completedRaw.
Entry point is now ResponderBase::finished = 0, instead of
completedRaw, where ResponderWithCompleted implements finished by
called completedRaw, but Responder doesn't: that directly calls
result/errorWithContent/error. Or, for the hack ResponderAdapter,
the entry points are pubResult/pubErrorWithContent.
Those are now the ONLY public methods, so more confusion.
mFinished is now set in all cases.
As a result of all that, it is no longer possible to accidently
pass a responder to ResponderAdapter that would break because it
expects completed() and completedRaw() to be called.
Added LLBufferArray::writeChannelTo.
Fixed bug for BlockingResponder::body (returned reference to temporary).
LLSDMessage::ResponderAdapter now allows a "timeoutpolicy" name
to be passed (not doing so results in the default timings), so
that the timeout policy of the used responder is retained.
Fixed llfasttimerview.cpp to test LLSDSerialize::fromXML() to return
a positive value instead of non-zero, because it may return -1 when the
parsing fails (three places).
Removed LLHTTPClient::Responder as base class from
LLFloaterRegionDebugConsole completely: it isn't a responder!
Several other responder classes were simplified a bit in order to
compile again with the above changes.
