templater: handle SyntaxError when parsing ui.logtemplate

Before, Mercurial would crash with a traceback ending with

  SyntaxError: unmatched quotes

if you configured

  [ui]
  logtemplate = {rev}\n

The SyntaxError is now catched and the string is re-parsed without
requiring quotes.

Translations are optional:

  $ "$TESTDIR/hghave" gettext || exit 80

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 accomodating 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)
