Revert of Add Linux support for the Bluetooth API. (patchset #10 id:90001 of

https://codereview.chromium.org/1367663002/ )

Reason for revert:
perf regression.
http://build.chromium.org/p/chromium/builders/Linux%20x64/builds/10130

Original issue's description:
> Add Linux support for the Bluetooth API.
>
> This refactors all the code in //device/bluetooth to be non-ChromeOS specific
> and adds code to enable all of it to run on Linux through the linux specific
> DBusThreadManager that is added.
>
> This CL depends on https://codereview.chromium.org/1347193004/
>
> Owners reviews requested,
> //device - armansito@
> //extensions - rockot@
> //chrome/browser/chrome_browser_main_linux.* - jhawkins@
