ETableState: Add a "specification" construct-only property.

ETableState now keeps a weak reference on the ETableSpecification to
which it's associated.  The plan is to replace the column index numbers
with a direct reference to an ETableColumnSpecification from the spec.

New functions:

  e_table_state_ref_specification()
