Reland 232312 (https://codereview.chromium.org/33363003/), with fix.
This was reverted in 232369 (And relanded and reverted again after that).

The problem was that, per spec, the "data" parameter returned to the
callback is valid until destroyed, but
ResourceFetcherTests.ResourceFetcherDeletedInCallback destoyed the fetcher
before reading the data parameter.  The CL also unintentionally introduced
a change where partially received content was returned on timeout.  I've
reverted to the old behavior.

Original CL description:
Cleanup ResourceFetcher in preparation to add to public content API,
in preparation to move error page logic from content to chrome:

* Merge ResourceFetcher and ResourceFetcherWithTimeout.
* Remove unnecessary member variables.
* Remove Cancel() (All consumers were deleting and cancelling at the
same time, anyways, and deleting already cancels).
* Make definition order match declaration order.
* Fix outdated comments.
