Merging SPDY IP connection pooling changes from the trunk (r93105)

Merging SPDY IP connection pooling changes from the trunk (r93105)

Changed SPDY's ip connection pooling logic to only add the used IP,
rather than all the IPs for the hostname, to the SpdyAliasMap.

This is to fix the following problem:

When we establish a new SPDY connection, we add all IP addresses for
that hostname to our alias map. Therefore, if we connect to host foo
which maps to IPs X, Y, and Z, but the actual IP we connect to is X,
then if we try to get a SPDY connection to host bar which maps to
IPs Y and Z, then currently we will share the SPDY connection to host
foo on IP X.

Hi Wan-Teh,
  I have merged the changes from the following CL into the branch. 

  Added SpdySessionPoolPeer class to spdt_test_util.h. Added getting
spdy_session_pool from spdy_session to unit test.

  Did a diff between the patches (they are the same except for the above
changes).

  Would appreciate if you could take a look at it.

thanks very much,
raman

LGTM.  I only reviewed spdy_session_pool.{cc,h}.
