url: more bytes/unicodes fussing in url.py around auth handling Once again, these methods are a little annoying to handle because they can get unicodes or bytes depending on who's calling. I think we can probably clean this up a TON once we can run something like pytype and do typechecking of our Python, but until then this is going to be the easy way out. This fixes test-http-bundle1.t. Differential Revision: https://phab.mercurial-scm.org/D2599

httpconnection: convert url to bytes in readauthforuri This method is sometimes called by the stdlib, so we just need to accept both bytes and unicodes here. Awesome. Differential Revision: https://phab.mercurial-scm.org/D2598

tests: prevent enormous output spew in test-lfs-largefiles.t This test currently fails on Python 3, but in a super-slow way. Adding this `head` invocation costs us nothing, but will prevent failures in this area from being super expensive. Differential Revision: https://phab.mercurial-scm.org/D2600
