Reviewed by Yury Semikhatsky.

Currently, we generate stack traces for console messages at each call
site. Bug 100650 has the end goal of moving all stack trace generation
inside of the Inspector in order to ensure that we never send a console
message without a stack trace if it's possible to generate one. This
also ensures that we never generate unused call stacks.

This patch is the first step in that direction, moving stack trace
generation out of the Console bindings, and into either Console or
InspectorConsoleAgent.

No visible change in behavior should result; this refactoring should
continue to pass all existing inspector tests.

* bindings/js/JSConsoleCustom.cpp:
(WebCore::JSConsole::profile):
(WebCore::JSConsole::profileEnd):
    Adjust custom JSC Console bindings to drop call stack generation.
* bindings/scripts/CodeGeneratorJS.pm:
(GenerateCallWith):
* bindings/scripts/CodeGeneratorV8.pm:
(GenerateCallWith):
    Drop call stack generation from JSC and V8 bindings.
* bindings/scripts/CodeGeneratorGObject.pm:
    Skip timeEnd explicitly in these bindings; it used to include
    ScriptArguments, which autoskipped it. Now it doesn't, so it needs
    to be called out on its own.
* bindings/v8/ScriptCallStackFactory.cpp:
(WebCore::createScriptCallStackForConsole):
(WebCore::createScriptCallStack):
(WebCore):
* bindings/v8/ScriptCallStackFactory.h:
(WebCore):
    Add 'createScriptCallStack(ScriptState*, size_t)' to V8's
    ScriptCallStackFactory in order to match JCS' implementation.
    It simply delegates to 'createScriptCallStackForConsole', which
    now also accepts a 'maxStackSize' parameter.
* bindings/v8/custom/V8ConsoleCustom.cpp:
(WebCore::V8Console::traceCallback):
(WebCore::V8Console::assertCallback):
(WebCore::V8Console::profileCallback):
(WebCore::V8Console::profileEndCallback):
    Adjust custom V8 bindings to drop call stack generation.
* inspector/InspectorConsoleAgent.cpp:
(WebCore::InspectorConsoleAgent::addMessageToConsole):
    With the eventual goal of getting rid of the call stack parameter
    entirely, this patch drops it from one version of
    'addMessageToConsole' (replacing it with ScriptState*), and creates
    a new version that only accepts a call stack. We should be able to
    migrate most (all?) external call sites over to the arguments
    version in future patches.
(WebCore):
(WebCore::InspectorConsoleAgent::count):
    Count takes 'ScriptState*' instead of a call stack, and generates
    the stack as needed.
* inspector/InspectorConsoleAgent.h:
(InspectorConsoleAgent):
* inspector/InspectorConsoleInstrumentation.h:
(WebCore::InspectorInstrumentation::addMessageToConsole):
(WebCore):
(WebCore::InspectorInstrumentation::consoleCount):
* inspector/InspectorInstrumentation.cpp:
(WebCore):
(WebCore::InspectorInstrumentation::addMessageToConsoleImpl):
(WebCore::InspectorInstrumentation::consoleCountImpl):
* inspector/InspectorInstrumentation.h:
(InspectorInstrumentation):
    Changes the InspectorInstrumentation pipeline to match the
    InspectorConsoleAgent changes.
* page/Console.cpp:
(WebCore::Console::addMessage):
    We now (always) generate one frame of a stack trace in order to
    populate line numbers and caller URLs. If we need to print the whole
    trace here, we generate a full stack.
(WebCore::Console::debug):
(WebCore::Console::error):
(WebCore::Console::info):
(WebCore::Console::log):
(WebCore::Console::warn):
(WebCore::Console::dir):
(WebCore::Console::dirxml):
(WebCore::Console::clear):
(WebCore::Console::trace):
(WebCore::Console::assertCondition):
(WebCore::Console::count):
(WebCore::Console::markTimeline):
(WebCore::Console::timeEnd):
(WebCore::Console::timeStamp):
(WebCore::Console::group):
(WebCore::Console::groupCollapsed):
(WebCore::Console::profile):
(WebCore::Console::profileEnd):
    s/ScriptCallStack/ScriptState*/g. Also, printing the stack trace
    has been moved out of 'trace' and into 'addMessage'.
* page/Console.h:
(Console):
* page/Console.idl:
    Drop the call stack, add the script state.
* workers/WorkerContext.cpp:
(WebCore::WorkerContext::addMessageToWorkerConsole):
    Use the new, explicitly call stacked addMessageToConsole. We'll kill
    this in a future patch.
