The static cleanup function in qqmldebugserver.cpp is only used if the
debug server is actually created. If not we can mark it as unused to
avoid compile warnings. Enclosing it in #ifdef would be uglier.

The debug services generally behave in one of two ways when initializing:
Either they block the initializing thread until some configuration is
passed over the network or they just go on. By introducing a generalized
configurable debug service the various ways of waiting on initialization
are cleaned up. The API defined for it also allows for engine-specific
initialization.

Previously the list of client plugins in the QQmlDebugServer could be
accessed concurrently from receiveMessage() and addService() either
when in non-blocking mode, or if the client uses service discovery or
sends additional hello messages after the first one.

Previously, if instance() was accessed concurrently we could run into
various problems as the initialization wasn't synchronized. By putting
most of the initialization into the constructor, wrapping it into a
Q_GLOBAL_STATIC and discerning between accesses that need to wait for
the initial "hello" packet and ones that don't the situation is
improved.

There's no real reason to disallow that. The only thing we want to check
there is that the registration doesn't take place in the debugger
thread. Disallowing registrations from anywhere but the main GUI thread
creates unnecessary problems with threaded QML profiling and debugging.

Make sure that the GUI thread & debugger thread actually sync on startup. So far
the GUI thread would block forever in waitCondition.wait() if the debugger thread

Also remove unused code and rename variables to make their use more obvious.

Using waitForMessage() in the constructor after registerService() is
_not_ safe: You might get the first message already after the
registerService() and before the waitForMessage() call. Instead,
use QMutex/QWaitCondition to block the initialization. Also make
the use of the block mode explicit, since the service might already
be enabled also for non-blocking modes ...
