Implements more debugger APIs on JavaScriptDebugServer and reduces
the number of callbacks to JavaScriptDebugListeners. These changes
will better facilitate debugger optimizations when SquirrelFish merges.

(WebCore::JavaScriptDebugServer::JavaScriptDebugServer): Initialize new data members.
(WebCore::JavaScriptDebugServer::~JavaScriptDebugServer): Delete all values of m_breakpoints.
(WebCore::JavaScriptDebugServer::removeListener): Call resume if the last listener was removed.
(WebCore::JavaScriptDebugServer::hasListenersInterestedInPage): Returns true if there are any
global listeners or a listener for the page.
(WebCore::JavaScriptDebugServer::addBreakpoint): Adds and entry to m_breakpoints.
(WebCore::JavaScriptDebugServer::removeBreakpoint): Removes a entry in m_breakpoints.
(WebCore::JavaScriptDebugServer::hasBreakpoint): Checks if there is a breakpoint for the
sourceID and line.
(WebCore::JavaScriptDebugServer::clearBreakpoints): Removed all breakpoints.
(WebCore::JavaScriptDebugServer::pauseOnNextStatement): Sets m_pauseOnNextStatement to true.
(WebCore::JavaScriptDebugServer::resume): Sets m_paused to false.
(WebCore::JavaScriptDebugServer::stepIntoStatement): Calls resume and sets
m_pauseOnNextStatement to true.
(WebCore::JavaScriptDebugServer::stepOverStatement): Calls resume and sets m_pauseOnExecState to
the current call frame's ExecState.
(WebCore::JavaScriptDebugServer::stepOutOfFunction): Calls resume and sets m_pauseOnExecState to
the current call frame's caller ExecState.
(WebCore::JavaScriptDebugServer::currentCallFrame): Returns m_currentCallFrame if paused.
(WebCore::dispatchDidParseSource): Removed the ExecState argument.

(WebCore::JavaScriptDebugServer::dispatchFunctionToListeners): Removes all the arguments passed
to the callback.
(WebCore::JavaScriptDebugServer::setJavaScriptPaused): Various overloaded functions
to pause parts of WebCore to prevent JavaScript execution while paused.
(WebCore::JavaScriptDebugServer::pauseIfNeeded): Decides if the debugger should pause based
on the passed in ExecState, source ID and line number. This checks for breakpoints, stepping, etc.
Calls didPause on all the listeners and spins a EventLoop until resume is called.

(WebCore::JavaScriptDebugServer::atStatement): Ditto.
(WebCore::JavaScriptDebugServer::returnEvent): Ditto.
