bundle2: add debug output for part generation

The part generation process was lacking a ui object and could not produce debug
output. It seems valuable to have some debug output on this part too, especially
now that we are planning to be able to hide it in the default --debug output.

#require gettext

(Translations are optional)

#if no-outer-repo

Test that translations are compiled and installed correctly.

Default encoding in tests is "ascii" and the translation is encoded
using the "replace" error handler:

  $ LANGUAGE=pt_BR hg tip
  abortado: n?o foi encontrado um reposit?rio em '$TESTTMP' (.hg n?o encontrado)!
  [255]

Using a more accommodating encoding:

  $ HGENCODING=UTF-8 LANGUAGE=pt_BR hg tip
  abortado: n\xc3\xa3o foi encontrado um reposit\xc3\xb3rio em '$TESTTMP' (.hg n\xc3\xa3o encontrado)! (esc)
  [255]

Different encoding:

  $ HGENCODING=Latin-1 LANGUAGE=pt_BR hg tip
  abortado: n\xe3o foi encontrado um reposit\xf3rio em '$TESTTMP' (.hg n\xe3o encontrado)! (esc)
  [255]

#endif

Test keyword search in translated help text:

  $ HGENCODING=UTF-8 LANGUAGE=de hg help -k blättern
  Themen:
  
   extensions Benutzung erweiterter Funktionen

Check Mercurial specific translation problems in each *.po files, and
tool itself by doctest

  $ cd "$TESTDIR"/../i18n
  $ python check-translation.py *.po
  $ python check-translation.py --doctest
  $ cd $TESTTMP
