http: handle push of bundles > 2 GB again (issue3017) It was very elegant that httpsendfile implemented __len__ like a string. It was however also dangerous because that protocol can't handle sizes bigger than 2 GB. Mercurial tried to work around that, but it turned out to be too easy to introduce new errors in this area. With this change __len__ is no longer implemented at all and the code will work the same way for short and long posts.
