Some bugs in evolution-data-server were causing us to hit Google's
daily limit for the CalDAV and Tasks APIs. The bugs have since been
fixed, but until every single user out there installs the fix,
everybody using the old keys will be susceptible even if they have a
fixed copy of evolution-data-server. This is because Google identifies
us by the API key and not the version of the code running on the
client.

We are therefore phasing out the old key, so that users updating their
systems have no connection to the one that was tainted by these bugs.

This is meant to specify the path to the templates file during the
build. Templates won't work if this is left out.

We can now use g_key_file_save_to_file which wraps g_key_file_to_data
and g_file_set_contents.

At the moment, g_key_file_to_data is documented as never throwing an
error. So we don't lose anything in terms of error reporting. Even if
this changes in the future, I think we can live without a separate
error message for g_key_file_to_data.

Bump minimum GLib version to 2.40.

gtk-doc works just fine with srcdir != builddir.

We should be pairing gtk_window_get_size gtk_window_set_default_size to
avoid inconsistencies between the size reading and setting code. eg.,
in recent GTK+ versions, gtk_window_get_size and
gtk_widget_set_size_request differ in their interpretation of the CSD
chrome.

However, gtk_window_set_default_size didn't work with non-resizable
GtkWindows, until now.

Bump minimum GTK+ version to 3.19.12 for the new GtkWindow size
handling logic.

Currently the --disable-telepathy switch only removes the Telepathy
account provider from the list, but not the dependencies. We should
remove the (then unused) Telepathy dependency too.

The backend will typically be a core OS component, where the client
library can be bundled with applications. Make it possible to build the
latter without the former.

Bump minimum WebKitGTK+ version to 2.7.2 because we need to create our
own WebKitWebContext and handle user script messages.

It does not work. There are currently no known applications that use
it. Keeping the code means that some distributions enable it, only to
have users complain that it does not work.

Will be restored once the situation changes.

As a result the minimum libsoup version was bumped to 2.42.
