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.

-/* Text item for the canvas. Text items are positioned by an anchor point and an anchor direction.
- *
- * A clipping rectangle may be specified for the text. The rectangle is anchored at the text's anchor
- * point, and is specified by clipping width and height parameters. If the clipping rectangle is
- * enabled, it will clip the text.
- *
- * In addition, x and y offset values may be specified. These specify an offset from the anchor
- * position. If used in conjunction with the clipping rectangle, these could be used to implement
- * simple scrolling of the text within the clipping rectangle.
- *
- * The following object arguments are available:
- *
- * name type read/write description
- * ------------------------------------------------------------------------------------------
- * text string RW The string of the text label
- * bold boolean RW Bold?
- * justification GtkJustification RW Justification for multiline text
- * fill_color string W X color specification for text
- * fill_color_gdk GdkColor* RW Pointer to an allocated GdkColor
- * clip_width gdouble RW Width of clip rectangle
- * clip_height gdouble RW Height of clip rectangle
- * clip boolean RW Use clipping rectangle?
- * fill_clip_rect boolean RW Whether the text item represents itself as being the size of the clipping rectangle.
- * x_offset gdouble RW Horizontal offset distance from anchor position
- * y_offset gdouble RW Vertical offset distance from anchor position
- * text_width gdouble R Used to query the width of the rendered text
- * text_height gdouble R Used to query the rendered height of the text
- * width gdouble RW A synonym for clip_width
- * height gdouble R A synonym for text_height
- *
- * These are currently ignored in the AA version:
- * editable boolean RW Can this item be edited
- * use_ellipsis boolean RW Whether to use ellipsises if text gets cut off. Meaningless if clip == false.
- * ellipsis string RW The characters to use as ellipsis. NULL = "...".
- * line_wrap boolean RW Line wrap when not editing.
- * break_characters string RW List of characters to optionally break on.
- * max_lines gint RW Number of lines possible when doing line wrap.
