Migrate callers of message_loop_proxy() to task_runner()

Migrate callers of message_loop_proxy() to task_runner()

Migrate callers of {MessageLoop,Thread}::message_loop_proxy() to
{MessageLoop,Thread}::task_runner(). Since the types at the call sites
have already been updated, this is just a bulk rename.

this doesn't need a top level owner to review. any way you can find someone else
to review this to spread the review load? thanks

Oh? I was hoping this would be pretty straightforward since its just moving
callers of one function to another compatible function without any other
changes. I'm happy to split it up if you think otherwise, but I originally
didn't do it since it felt a bit pointless. WDYT?

[Sami, 2015-06-12 17:19:18]

(btw, I've now split out the biggest components -- does it look more reasonable
now?)

Thanks John! armansito@, could you check
device/bluetooth/bluetooth_socket_thread.cc please?

[Sami, 2015-06-17 01:32:19]

I'll TBR device/bluetooth/bluetooth_socket_thread.cc since the change there is
trivial and matches all the other changes here.
