- Collect all shell modules into a new top-level 'modules' directory:
$(top_srcdir)/modules/addressbook
$(top_srcdir)/modules/calendar
$(top_srcdir)/modules/mail
Nothing is allowed to link to these, not plugins nor other modules.
THIS SOLVES BUG #571275 AND OPENS THE DOOR TO PORTING TO MAC OS X.
- Mimic the libevolution-mail-shared library from master (except drop
the "shared" suffix) and have libevolution-mail-importers and all
mail-related plugins link to it.
- Discard the a11y subdirectories and have the files live alongside
their counterpart widgets.
