- Updated all L10N language/country references to use ISO 639-3 (language)
and ISO 3166-1 alpha 3 (country) codes.
- Note that holiday files are not updated.
- Many files were missing an explicit cmake.h include. Some were not including
it at all. Now it's used almost everywhere.
(cherry picked from commit 82ae86979c497e6d1d0c6b2b5a55aa379ec82c98)
- Cleaned up existing extension debris, in anticipation of the new mechanisms to
be included in future releases. This includes install/uninstall and a full
set of triggers.
- Added support for more type-specific checks of attribute values.
- Added support for more type-specific attribute rendering.
- Improved generalized methods for checking columns in a report.
- Added unit tests.
- Minor code cleanup.
- Added secret hidden feature for internal testing.
- Obsoleted Command::exectute 'commandLine' argument. It is worse
than unnecessary, it is an uncategorized raw argument string, which
is only really useful for the 'execute' command, which itself now
calls Arguments::combine to reconstruct the command line string.
