ui: swallow EBADF on stderr

ui.write_err already swallows EPIPE and EIO if a write to stderr fails.
On Mac OS X at least, a write to a closed file descriptor results in
EBADF. Before this patch, hg would exit with status 1 if a write to
stderr failed during startup (e.g. while trying to print a warning about
not finding an extension):

  $ ./hg --config extensions.foo= version 2>&-; echo $?
  1

With this patch, it correctly swallows stderr and continues to run the
command:

  $ ./hg --config extensions.foo= version 2>&-
  Mercurial Distributed SCM (version 2.1)
  ...

  $ "$TESTDIR/hghave" bzr114 || exit 80
  $ . "$TESTDIR/bzr-definitions"

The file/directory replacement can only be reproduced on
bzr >= 1.4. Merge it back in test-convert-bzr-directories once
this version becomes mainstream.
