Summary
std::bind not compiling with Visual Studio

I'm getting lots of compile errors like this when compiling after
r166496
and I'm trying to avoid adding template parameters everywhere. This is a shot-in-the dark solution. 1>..\platform\graphics\gstreamer\WebKitWebSourceGStreamer.cpp(745): error C2668: 'WTF::GMainLoopSource::schedule' : ambiguous call to overloaded function C:\Projects\BuildSlave\win-cairo-release\build\WebKitBuild\Release_WinCairo\include\private\wtf/gobject/GMainLoopSource.h(55): could be 'void WTF::GMainLoopSource::schedule(const char *,std::function<bool (GIOCondition)>,GSocket *,GIOCondition,std::function<void (void)>,GMainContext *)' C:\Projects\BuildSlave\win-cairo-release\build\WebKitBuild\Release_WinCairo\include\private\wtf/gobject/GMainLoopSource.h(54): or 'void WTF::GMainLoopSource::schedule(const char *,std::function<bool (void)>,int,std::function<void (void)>,GMainContext *)' C:\Projects\BuildSlave\win-cairo-release\build\WebKitBuild\Release_WinCairo\include\private\wtf/gobject/GMainLoopSource.h(53): or 'void WTF::GMainLoopSource::schedule(const char *,std::function<void (void)>,int,std::function<void (void)>,GMainContext *)' while trying to match the argument list '(const char [32], std::_Bind<true,void,void (__cdecl *const )(WebKitWebSrc *),WebKitWebSrc *&>, int, webKitWebSrcSeekDataCb::<lambda_d0654a0fb2d903f9cc92bf36e3e47024>)'

Patch View in context:
https://bugs.webkit.org/attachment.cgi?id=228238&action=review
We use the versions with the bool function to decide whether to use g_idle or g_timeout, if you remove the versions receiving a bool function it's impossible to implement a repeating source. I guess the problem with visual studio is that the compiler doesn't know which one to use, so a possible workaround would be to add a cast in the callers, see the discussion here:

Removing the code that doesn't build for you is not a build fix :-)

That's why it was a shot in the dark. I was just hoping that nobody would ever need to use the bool version :) I added some std::function<void ()> constructors. I was going to add static_casts, but I think this is a better solution.
