Consolidate base utility libraries into libeutil.
Evolution consists of entirely too many small utility libraries, which increases linking and loading time, places a burden on higher layers of the application (e.g. modules) which has to remember to link to all the small in-tree utility libraries, and makes it difficult to generate API documentation for these utility libraries in one Gtk-Doc module. Merge the following utility libraries under the umbrella of libeutil, and enforce a single-include policy on libeutil so we can reorganize the files as desired without disrupting its pseudo-public API. libemail-utils/libemail-utils.la libevolution-utils/libevolution-utils.la filter/libfilter.la widgets/e-timezone-dialog/libetimezonedialog.la widgets/menus/libmenus.la widgets/misc/libemiscwidgets.la widgets/table/libetable.la widgets/text/libetext.la This also merges libedataserverui from the Evolution-Data-Server module, since Evolution is its only consumer nowadays, and I'd like to make some improvements to those APIs without concern for backward-compatibility. And finally, start a Gtk-Doc module for libeutil. It's going to be a project just getting all the symbols _listed_ much less _documented_. But the skeletal structure is in place and I'm off to a good start.

+ * The ETableCol represents a column to be used inside an ETable. The
+ * ETableCol objects are inserted inside an ETableHeader (which is just a
+ * collection of ETableCols). The ETableHeader is the definition of the
+ * order in which columns are shown to the user.
+ *
+ * The @text argument is the the text that will be shown as a header to the
+ * user. @col_idx reflects where the data for this ETableCol object will
+ * be fetch from an ETableModel. So even if the user changes the order
+ * of the columns being viewed (the ETableCols in the ETableHeader), the
+ * column will always point to the same column inside the ETableModel.
+ *
+ * The @ecell argument is an ECell object that needs to know how to
+ * render the data in the ETableModel for this specific row.
+ *
+ * Data passed to @compare can be (if not %NULL) a cmp_cache, which
+ * can be accessed by e_table_sorting_utils_add_to_cmp_cache() and
+ * e_table_sorting_utils_lookup_cmp_cache().
+ *
+ * Returns: the newly created ETableCol object.
