A simple Evolution run and move between all views means creation of
more than 100 GSettings objects, with only a bit more than 10 schemas.
Reusing the objects should have a positive impact on a performance too.
* use e_util_win32_initialize() in main() to avoid code duplication
* e-spinner - correct image path build under win32
* export WIN32_SERVICELIBEXECDIR when building eds, which relies on it now
* update D-Bus patch and session-local.conf creation, thus D-Bus
can actually autostart services
This makes the code free of Coverity scan issues.
It is sometimes quite pedantic and expects/suggests some
coding habits, thus certain changes may look weird, but for a good
thing, I hope. The code is also tagged with Coverity scan
suppressions, to keep the code as is and hide the warning too.
Also note that Coverity treats g_return_if_fail(), g_assert() and
similar macros as unreliable, and it's true these can be disabled
during the compile time, thus it brings in other set of 'weird'
changes.
DConf load command requires a slash at the end of the path to load,
but the replace_variables() code always removed the trailing slash,
which made the configuration load nonfunctional.
Store the Evolution version used to create the backup file in the
evolution.dir file which is part of the tarball.
After restoring the backup file we need to reset the last-used-version
key in GSettings to the version listed in the evolution.dir file so the
proper migration routines run when Evolution is restarted.
