Retrieving a "large" bookbag results in the call timing out

[Dale Rigney]

The call to retrieve bucket items needs to be done as a stream and not one big call. When the call is made as one big call the size of the full request becomes too large resulting in an "Internal Server Error". The call becomes too large when the bookbag contains around 350 or more items.

I've pushed a patch to working/user/berick/lp1166836-tpac-large-bbag-stream -- I have confirmed bucket items are now received one at a time (streaming mode) instead of all in one batch. I have not tested against a sufficiently large data set, though.

And just to be clear, this is in the TPAC My Lists page with the large bucket in question expanded / opened in the UI.

Tested this with two accounts in our system with over 450+ entries in their bookbag. It went from timing out entirely to taking a long time, but eventually still showing all the hits successfully.

Picked to master and backported clean to rel_2_3 and rel_2_2.

Thanks Dale and BIll!
