Infinite recursion in requests w/Origin header

[Samuel Merritt]

If you make an object GET request with the Origin header set, you wind up with cors_validation and get_info calling each other in a mutually-recursive death spiral.

The horrifying thing is that it doesn't fail the request; somehow, something eats the stack overflow and and it all works out. It does slow things down a bunch though.

    Drop origin from get_info calls

    The reason for this is that having origin in the get_info calls causes an
    infinite loop. The way that code was written it relies on GETorHEAD_base to
    populate the data- the only problem is that the HEAD call is wrapped by
    cors_validation which calls get_info and round and round we go. imo get_info
    should be refactored to not work this way (relying on this other call to do
    stuff behind scenes and then magically your stuff is there) because it seems
    pretty prone to breaking. But I'll let somebody else do that :).

    Fixes bug 1270039
