tests: force \n newlines when writing to sys.stdout

Without this, Python 3 on Windows inserts some \r that aren't
present in the input, causing test-http-bad-server.t to fail.
After this change, the test passes on Python 3 on Windows!

Error is handled reasonably. We override the phabtoken here so that
when you're developing changes to phabricator.py you can edit the
above config and have a real token in the test but not have to edit
this test.

  exchangev2: start to implement pull with wire protocol v2
  
  Wire protocol version 2 will take a substantially different
  approach to exchange than version 1 (at least as far as pulling
  is concerned).
  
  This commit establishes a new exchangev2 module for holding

TODO: "bin2" can't be viewed in this commit (left or right side), and the URL
looks much different than when viewing "bin2_moved".  No idea if this is a phab
bug, or phabsend bug.  The patch (as printed by phabread) look reasonable
though.

  $ hg mv bin2 bin2_moved
  $ hg ci -m "moved binary"

Note: "bin2_moved" is also not viewable in phabricator with this review

  $ hg cp bin2_moved bin2_copied

Note: "bin2_moved_again" is marked binary in phabricator, and both sides of it
are viewable in their proper state.  "bin2_copied" is not viewable, and not
listed as binary in phabricator.

  repoview: add a new attribute _visibilityexceptions and related API
  
  Currently we don't have a defined way in core to make some hidden revisions
  visible in filtered repo. Extensions to achieve the purpose of unhiding some
  hidden commits, wrap repoview.pinnedrevs() function.
  
  To make the above task simple and have well defined API, this patch adds a new
  attribute '_visibilityexceptions' to repoview class which will contains
  the hidden revs which should be exception.
  This will allow to set different exceptions for different repoview objects
  backed by the same unfiltered repo.
  
  This patch also adds API to add revs to the attribute set and get them.
  
  Thanks to Jun for suggesting the use of repoview class instead of localrepo.
