The Calendar, Memos and Tasks views use to do D-Bus calls to
the backends on the main (UI) thread, which could result in UI
freezes, until the operation was done on the backend (and server)
side. This commit fixes that by invoking the operations in
a dedicated thread. It has few additional advantages too:
- operations can be cancelled
- proper error reporting to a user
- less code duplication between the views for common operations
There had been fixed some performance issues when selecting/unselecting
sources in the source selector as well.
- 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.
