Add a new -i/--isodate option to `debugstate'

The localized version of date/time displayed by the '%x %X'
format may vary depending on the current timezone setup.  When
debugstate runs with the new -i/--isodate option, it will always
display the date using '%Y-%m-%d %H:%M:%S' as the strftime format
string.  This makes debugstate output more predictable, and
easier to parse in an automated manner.

An example of the difference, when running with a Greek locale
environment on FreeBSD, is:

  $ hg debugstate | head -3
  n 664        320 01/09/08 19:56:54 .hgignore
  n 664        792 01/09/08 19:56:54 .hgsigs
  n 664        829 01/09/08 19:56:54 .hgtags
  $ hg debugstate -i | head -3
  n 664        320 2008-01-09 19:56:54 .hgignore
  n 664        792 2008-01-09 19:56:54 .hgsigs
  n 664        829 2008-01-09 19:56:54 .hgtags
  $
