Change net/nqe and some url_request tests to use new URLRequest API
This cl splits the big CL with changes to net/ folder and
has changes only to net/nqe and some url_request tests
according to the changes to URLRequest API.
What the big cl does:
It modifies net/ clients that use URLRequest API as long as
URLRequest::Read returns int net errors and
URLRequest::Delegate and NetworkDelegate methods
(for example, OnResponseStarted or OnCompleted) have int
net_error in the arguments now.
The reason behind splitting the CL into small one is that
an android bot started to be unstable and unittests became
flaky. It was not possible to locate the problem and the
decision was to split the CL and upload small parts with a
6+ hours interval in order to make it possible to locate
the problematic code.
The big CL is located here -
