commit 3b60901cd16927a20269cfc7177997f2584912c6
Author: Bence Béky <bnc@chromium.org>

Clean up UnclaimedPushedStreamContainer API.

In preparation for moving UnclaimedPushedStreamContainer functionality
into Http2PushPromiseIndex, rename
UnclaimedPushedStreamContainer::find() to FindStream() and rename
Http2PushPromiseIndex::Find() to FindSession(), so that when both
methods live in Http2PushPromiseIndex, there will be no name collision.

Also, remove publicly exposed UnclaimedPushedStreamContainer::iterator,
instead introduce new constant kNoPushedStreamFound to be returned by
FindStream() if no stream is found.  (This will also be used by other
Http2PushPromiseIndex methods, see https://crrev.com/c/734223 for proof
of concept.)

Also, remove empty(), size(), begin(), end(), count(), lower_bound(),
and erase by iterator methods from UnclaimedPushedStreamContainer, and
rename size to CountStreamsForSession().

New method names will make sense when they all are moved to
Http2PushPromiseIndex in the next CL.

commit a12c770e918a69cc0bbba2d2579c22ff6ae76936

Record stream IDs in Http2PushPromiseIndex.

Stop using SpdySession instances in Http2PushPromiseIndexTests.  This
makes tests much simpler.

Rename SpdySessionKey::Equals() to SpdySessionKey::operator==() so that
it can be tested by gMock.  This conforms to the style guide "prefer to
define == [...] rather than Equals()", see
https://google.github.io/styleguide/cppguide.html#Operator_Overloading

Define struct UnclaimedPushedStream instead of using std::pair or
std::tuple.  Named members are much nicer than first, second, or get<>.

Define CompareByUrl in conformance with the same section of the style
guide "if your type doesn't have a natural ordering [...] use a custom
comparator rather than overloading <".

The next CL will merge SpdySession::UnclaimedPushedStreamContainer into
Http2PushPromiseIndex.  For this, two sets of UnclaimedPushedStream
entries will need to be maintained with identical
contents but different ordering.  The other will be done by
CompareByDelegate and will allow efficient lookup of entries for a given
Delegate.

Remove SpdySession::UnclaimedPushedStreamContainer.

Add methods to Http2PushPromiseIndex so that it could take over the
functionality of SpdySession::UnclaimedPushedStreamContainer.
