Qt: Expose document-supplied text direction
glib: Implement accessors for element attributes

Implement inspecting the standard attributes of PopplerStructureElement
objects.

glib: Rename PopplerStructureScope as PopplerStructureTableScope

It's a table specific attribute
glib: Update the documentation symbols after the PopplerStructureScope rename
Rename getNumElements, getElement and appendElement as getNumChildren, getChild and appendChild

It's more consistent with other internal API and less confusing.
glib: Add missing underscore in method name

The correct name is poppler_structure_element_get_form_state().

glib: Use flags argument in poppler_structure_element_get_text()

Instead of accepting a boolean argument to enable recursive text extraction,
use a flags value. Text extraction may add features in the future (for
example, allowing using alternate text as replacement for inline figures),
and this will allow to extend the method without introducing ABI or API
breakage.
