When using "inherit CMS language", fr will always use fr_FR, not fr_CA (also affects pt_BR)

Using CiviCRM 3.2 svn trunk, if I activate "inherit CMS language" in Admin/Settings/Localization, the CiviCRM interface will always use fr_FR, and not fr_CA.

This has to do with how CRM/Utils/System/Drupal/getUFLocale() uses CRM_Core_I18n_PseudoConstant::languages() to get available languages, then uses whatever regional language is last alphabetically for a given language. So fr_FR is alphabetically after fr_CA, and therefore "wins".

My first thought was to delete i10n/fr_FR translation files, but then CiviCRM fallsback to English, since it really only looks for fr_FR.

I experimented with CRM_Core_I18n::languages(), which checks if the language files really exist, which would at least allow users to easily disable fr_FR from their installations, but getUFLocale() is called too early in the process and $config is not yet fully populated, so itt does not find the location of the l10n directory.

I ended up copying fr_CA over fr_FR files to make it work.

Since the translation system may change in the short term, and given that few people use fr_CA, I recommend just closing the issue for now.

Note that this also affects pt_BR.
