Removing TryPostTask functionality

This is mostly a logical revert of
https://chromiumcodereview.appspot.com/14387002/

Because nobody uses it anymore. At that time there was
resistance about having this but there was a client (the audio code)
that wanted something like this to avoid polling. I don't know what
the audio code does (I so hope is not polling) but certainly is
not using this.
