This patch prepares AIStateMachine for the use of AITimer together
with calls to set_state() from other threads. The extra problem
in this case is that the main-thread CAN start running the state
machine again (when the timer times out), while before it was
assumed to be idle until a thread called set_state.
This also takes into account that a thread might call set_state()
and then AGAIN call set_state() before the main thread gets the
chance to call idle() inbetween.
Bug fixes:
AICurlEasyRequestStateMachine didn't delete itself.
curl_multi_socket_action calls were made for potentional removed sockets.
The curl thread wasn't terminated.

Basically removed (not used anyway)

Basically removed (just includes aiculr.h now)

CurlUseMultipleThreads was remvoved.
CurlMaximumNumberOfHandles and CurlRequestTimeOut
are still in there, but unused at the moment.

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).
