74dff061ff Support for new LL Responder API.
This adds mStatus, mReason and mContent to ResponderBase
and fills those in instead of passing it to member functions.
The added danger here is that now code can accidently try
to access these variables while they didn't already get a
correct value.

Affected members of ResponderBase (that now have less arguments):
decode_llsd_body, decode_raw_body, completedHeaders,
completed -> httpCompleted, result -> httpSuccess,
errorWithContent and error -> httpFailure.

New API:

ResponderBase::setResult
ResponderBase::getStatus()
ResponderBase::getReason()
ResponderBase::getContent()
ResponderBase::getResponseHeaders() (returns AIHTTPReceivedHeaders though, not LLSD)
ResponderBase::dumpResponse()
ResponderWithCompleted::completeResult
ResponderWithResult::failureResult (previously pubErrorWithContent)
ResponderWithResult::successResult (previously pubResult)

Not implemented:

getHTTPMethod() - use getName() instead which returns the class name of the responder.

completedHeaders() is still called as usual, although you can ignore
it (not implement in a derived responder) and call getResponseHeaders()
instead, provided you implement needsHeaders() and have it return true.

However, classes derived from ResponderHeadersOnly do not have
completedHeaders(), so they still must implement completedHeaders(),
and then call getResponseHeaders() or just access mReceivedHeaders
directly, as usual.

0b265320a9 Code clean up.
* 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

65e012c540 More curl fixes and changes.
* Moved LegacyPolledResponder::mCode to ResponderBase::mCode.
* Added a parameter to ResponderBase::finished (and pubError*) to set mCode.
* Renamed ResponderBase::decode_body to decode_llsd_body and added ResponderBase::decode_raw_body.
* Use LegacyPolledResponder::finished instead of LegacyPolledResponder::completed_headers
  to set remaining cached values.
* Fixed assertion in case of -DCWDEBUG and upload finish detection failure in case of HEAD
  method (mDebugIsGetMethod -> mDebugIsHeadOrGetMethod).
* Add XmlTreeInjector : support for LLXmlTree.
* Split BlockingResponder into BlockingLLSDResponder and BlockingRawResponder.
* Final blocking responders are now: BlockingLLSDPostResponder, BlockingLLSDGetResponder
  and BlockingRawGetResponder.
* Added LLHTTPClient::blockingGetRaw
* Got rid of hipporestrequest.* -- and fixed hippogridmanager.cpp to use
  LLHTTPClient::blockingGetRaw instead, and fixed llviewermessage.cpp to use
  AICurlInterface::ResponderWithCompleted and decode_raw_body instead of
  HippoRestHandlerRaw and LLHTTPClient::get4 instead of HippoRestRequest::get5.

2a88f7d7c4 ResponderAdapter stuff
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.

3f1fb9a66e Add improved timeout handling for HTTP transactions.
Introduces AIHTTPTimeoutPolicy objects which do not just
specify a single "timeout" in seconds, but a plethora of
timings related to the life cycle of the average HTTP
transaction.

This knowledge is that moved to the Responder being
used instead of floating constants hardcoded in the
callers of http requests. This assumes that the same
timeout policy is wanted for each transaction that
uses the same Responder, which can be enforced is needed.

I added a AIHTTPTimeoutPolicy for EVERY responder,
only to make it easier later to tune timeout values
and/or to get feedback about which responder runs
into HTTP errors in debug output (especially time outs),
so that they can be tuned later. If we already understood
exactly what we were doing then most responders could
have been left alone and just return the default timeout
policy: by far most timeout policies are just a copy
of the default policy, currently.

This commit is not finished... It's a work in progress
(viewer runs fine with it though).

Conflicts resolved by choosing curlthreading2
for any llmessage file regardless (which looks
correct upon investigation); the rest also
turned out to need to use curlthreading2, except
in one line where I added a semi-colon after
an assert(), and the assert was changed in
singu/master.

	  Lock mSignal always (is unlocked inside wait()).
	  Use mSignal lock to see if we are waiting; remove mWaiting.
	  Return false from the MeshFetch functions iff we have to retry
	  a HTTP fetch. Catch the error exception thrown by getByteRange
	  instead of using it's return value (always returns true
	  anyway).

b8744b9e6a LLViewerRegion WIP: Added all headers that are dragged in.
Most in particular llevents.h, which comes along with
the demand that the old events in llevent.h are put
in a namespace LLOldEvents. Made all changes necessary
to compile the rest of the code again (without changing
the actual code: it's still using the old events).

This patch also removes LLStopWhenHandled and LLStandardSignal
from indra/llui/llnotifications.h because those are
moved to llevents.h. That seems to be the only change
to indra/llui/llnotifications.h that isn't floater related,
so I left the rest of that file alone.
