blackbox: properly replace ui class

Without this, anyone creating a ui object using: uimod.ui()
skips the blackbox.

Also, anyone doing ui.copy() skipped the blackbox.

Unfortunately, the ui object lifestyle is a bit messy,
the first one that's created is never actually initialized
with subclasses, instead pieces of the subclass are adopted
into the primal ui object. In order to handle this, a
_partialinit method will be called to ensure that the
blackboxui is properly initialized.

  $ hg init
  $ touch a

  $ unset HGUSER
  $ echo "[ui]" >> .hg/hgrc
  $ echo "username= foo" >> .hg/hgrc
  $ echo "          bar1" >> .hg/hgrc

  $ hg ci -Am m
  adding a
  abort: username 'foo\nbar1' contains a newline

  $ rm .hg/hgrc

  $ HGUSER=`(echo foo; echo bar2)` hg ci -Am m
  abort: username 'foo\nbar2' contains a newline
  
  [255]
  $ hg ci -Am m -u "`(echo foo; echo bar3)`"
  transaction abort!
  rollback completed
