* glom/libglom/data_structure/layout/fieldformatting.cc:

* glom/libglom/data_structure/layout/fieldformatting.[h|cc]:
  Added a get_choices_related() overload that returns the LayoutItem_Fields
  instead of just the field names. This reduces the copy/pasted code in the
  callers, and makes it easier to support related fields in future.
* glom/libglom/utils.[h|cc]:
* glom/mode_data/datawidget/combochoices.[h|cc]:
* glom/utility_widgets/db_adddel/db_adddel.cc: Adapted and made necessary
  const corrections.

	* glom/mode_data/datawidget/combochoices.[h|cc]:
  refresh_data_from_database_with_foreign_key(): Add a document parameter,
  used to update the cached choices information if necessary.
	* glom/mode_data/flowtablewithfields.cc: set_field_value(): Adapted.

* glom/application.cc: on_document_load(): Don't just fail silently when
  there is an unexpected error, for instance if the postgres data directory
  is missing.

* glom/libglom/utils.[h|cc]: build_sql_select_with_key(): Add a sort_clause
  parameter.
  get_choice_values(field): Rename this to get_choice_values_all() and change
  the implementation to just call the other get_choice_values(). Add
  a Document* parameter so we can do that.
  get_choice_values(document, field, ...): Sort the list by the first field.
  This should probably be an option in the developer-mode UI.
* glom/mode_data/datawidget/combo.h:
* glom/mode_data/datawidget/combochoices.[h|cc]:
* glom/mode_data/datawidget/comboentry.h:
* glom/utility_widgets/db_adddel/db_adddel.cc:
  get_choice_values(): Adapt to the change, by adding a Document* parameter.
* glom/base_db.cc: Adapt.

* configure.ac: Drop unnecessary AC_DISABLE_STATIC. Use AS_IF rather
than shell if...fi. Add a TODO.
* Makefile.am:
* Makefile_tests.am: Take advantage of dependencies to reduce
duplication of linker flags.

* glom/utility_widgets/db_adddel/db_adddel.[h|cc]: Added set_cell_choices(),
  using it in refresh_cell_choices_data_from_database_with_foreign_key() and
  construct_specified_columns_cellrenderer().

	* glom/libglom/utils.[h|cc]: Added a get_choice_values() overload that
	takes the foreign_key.
	* glom/utility_widgets/db_adddel/db_adddel.[h|cc]: Added get_choice_index()
	to get the affected choice lists when a field value changes.
	Added refresh_cell_choices_data_from_database_with_foreign_key() to update
	these lists.
	set_value(): Use these methods to update choice lists when appropriate,
	as already happens in the Details view.

* glom/utility_widgets/db_adddel/db_adddel.[h|cc]:
get_data_model_column_index(): Add a including_specified_field_layout bool
parameter, used in a new set_value() method overload that has a
set_specified_field_layout bool parameter.
user_changed(): Call set_value() to show the new value in any other
instances of the same field.
The details view already does this.

* glom/mode_data/flowtablewithfields.[h|cc]: set_value(), set_other_value():
  Avoid copy/pasting of the code.

	* glom/libglom/data_structure/layout/fieldformatting.[h|cc]: Renamed
	set/get_choices() to set/get_choices_related().
	* glom/libglom/utils.cc:
	* glom/libglom/document/document.cc:
	* glom/mode_design/layout/layout_item_dialogs/box_formatting.cc:
	* glom/utility_widgets/db_adddel/db_adddel.cc: Adapted.

	* glom/mode_data/datawidget/combochoices.[h|cc]: Remove the non-default
	constructor that took a second field.
	Move set_choices_with_second() to private.
	Add set_choices_related() and matching member variables.
	Add refresh_data_from_database_with_foreign_key(), like the one in
	Box_Data_RelatedRecords, which gets the related values and calls
	set_choices_with_second().
	* glom/mode_data/datawidget/combo.[h|cc]:
	* glom/mode_data/datawidget/combo_as_radio_buttons.[h|cc]:
	* glom/mode_data/datawidget/combochoiceswithtreemodel.[h|cc]:
	* glom/mode_data/datawidget/comboentry.[h|cc]: Adapt to the changed
	ComboChoices base API.
	* glom/mode_data/datawidget/datawidget.cc:
	create_combo_widget_for_field(): Do not take the second field as a parameter,
	because that is now specified later.
	Constructor: Simplify the code now that ComboChoices does more of the work.
	* glom/mode_data/flowtablewithfields.cc: set_field_value(): Call
	refresh_data_from_database_with_foreign_key() on the choice widgets as it
	already does on the portals, to refresh the list of possible values.

* glom/mode_data/datawidget/datawidget.cc: Constructor: Only fill the
choices list at this point if show_all is set.
* glom/mode_data/flowtablewithfields.[h|cc]: Addef get_choices_widgets(),
like the existing get_portals() methods.

* glom/glom_developer.glade:
* glom/libglom/data_structure/layout/fieldformatting.[h|cc]:
* glom/mode_design/layout/layout_item_dialogs/box_formatting.[h|cc]:
Add a Show All checkbox to the Related Choices section, so the developer
may choose to restrict the choices depending on the relationship. The default
(the previous behaviour) is to show all records from the related table.
* glom/libglom/document/document.cc: save_before_layout_item_formatting(),
save_after_layout_item_formatting(): Store the new bool in the document.
* glom/libglom/utils.cc:
* glom/mode_data/datawidget/datawidget.cc:
* glom/utility_widgets/db_adddel/db_adddel.cc: Adapt the code to build, though
the behaviour has not changed yet.

* tests/test_selfhosting_new_empty.cc: Fix the use of Utils::.

* configure.ac: Change the GLOM_ABI_VERSION number.
* Makefile.am:
* Makefile_libglom.am:
* docs/pyglom_reference/Makefile.am:
* docs/pyglom_reference/index.rst.in:
* glom/libglom/init.h:
* glom/python_embed/python_module/py_glom_module.cc:
* tests/test_load_python_library.cc:
* win32/build-installer:
* win32/glom.iss.in: Change mentions of 1.14 to 1.16.

* glom/bakery/app_withdoc_gtk.cc: Remove use of Gtk::RecentManager::set_limit().
* glom/dialog_existing_or_new.[h|cc]:
* glom/frame_glom.[h|cc]:
* glom/mode_data/notebook_data..[h|cc]:
* glom/mode_design/report_layout/dialog_layout_report.[h|cc]:
* glom/notebook_glom.[h|cc]: Replace use of GtkNotebookPage with Gtk::Widget*
in switch_page signal handlers.

* glom/libglom/connectionpool_backends/postgres.cc:
change_column(): Prefix the table name to the constraint name when
setting/removing the unique-key constraint, as libgda (or PostgreSQL)
seems to do when creating a field. This prevents a clash when two tables
have the same field name, and both should be unique.
This is nasty code anyway that I would rather have in libgda.
This fixes bug #625192 (fmyhr).

* glom/application.[h|cc]: Added init() with a bool restore option,
  calling do_backup_restore() if appropriate.
* glom/main.cc: Added a --restore command and pass the bool result to
  Application::init().

  This allows the user to restore from a backup without first loading an
  existing file, though this is so far only possible via the terminal.

* glom/application.[h.cc]: Added a Developer/Restore Backup menu item,
  which lets the user choose a .tar.gz, untars it in /tmp/ and opens it.

* tests/test_selfhosting_new_empty.cc:
* glom/libglom/utils.[h|cc]: Move delete_directory() to Utils.
  Added get_directory_child_with_suffix(), used to find the .glom file inside
  an untarred directory.

	* glom/glom_document.dtd: Add the startup_script node, so that
  the examples validate again.
	* glom/libglom/document/document.cc: set_child_text_node():
  Do not add new empty nodes. This keeps the document smaller.

* glom/application.[h|cc]: on_document_load(): Simplify the code to
  create from a backup, modifying the from-example code to handle it too,
  calling a new recreate_database_from_backup() method.
  That now creates the database and then adds the groups before trying
  to restore from the backup file.
* glom/libglom/connectionpool_backends/backend.h: convert_backup():
* glom/libglom/connectionpool_backends/postgres.[h|cc]: convert_backup():
* glom/libglom/connectionpool_backends/sqlite.[h|cc]: convert_backup():
  Add a database_name_parameter. This now expects the database to exist
  already, though it should be empty. It should also already have the
  expected groups.
* glom/libglom/connectionpool.[h|cc]: convert_backup(): Supply the
  database name. Also update the meta data so we know about the new tables.

* examples/example_smallbusiness.glom: Give some privileges to the
    accounts and personnel groups and resave-as-an-example. These were
    probably lost some time.

* glom/libglom/document/document.cc: set_modified(): Actually use
    m_allow_auto_save so we don't just save every time, overwriting
    previous saves. For instance, the examples were saved with is_example=false
    after the document was changed back.

* glom/base_db.[h|cc]: Added set_table_privileges_groups_from_document().
* glom/application.cc: recreate_database_from_example(): call it.

* glom/base_db.[h|cc]: Added add_groups_from_document().
* glom/application.cc: recreate_database_from_example() call it.

* glom/mode_data/notebook_data.cc:
* glom/mode_find/notebook_find.cc: Use Gtk::Notebook::append_page()
    instead of Gtk::Notebook::pages().push_back().

Many files: Try to include box.h or dialog.h before other treemodel.h.
    Sometimes just add a gtkmm.h to simplify things. This will not be necessary
    with gtkmm-3.0 (in glom's master branch).

* glom/application.cc: on_menu_developer_export_backup(): Suggest
    a directory name based on the current name and the date/time.
    Also use the directory name for the .glom filename, as we usually would do,
    instead of calling it just backup.glom.

* configure.ac: Check for the tar and gzip executables.
* glom/application.cc: on_menu_developer_export_backup(): Use tar
    via the command line, to put it all in a .tar.gz, so it is self-contained.

* glom/libglom/connectionpool_backends/postgres.[h|cc]:
* glom/libglom/connectionpool_backends/postgres_self.[h|cc]:
    Move create_text_file() from PostgresSelf to Postgres and add an
    only_for_current_user bool parameter, so we can use it in a
    new save_password_to_pgpass() method.
    save_backup(), convert_backup(): Temporarily store the password in
    ~/.pgpass, so pg_dump and pg_restore actually work.

* glom/application.[h|cc]: on_document_load(),
    on_menu_developer_export_backup(): Show a pulsing progress dialog while
    waiting for backup exporting and restoring.
    on_menu_developer_export_backup(): Close the file chooser dialog as soon
    as we stop using it.

	* glom/libglom/document/document.[h|cc]: Added get/set_is_backup_file(),
	saved in the XML document..
  on_menu_developer_export_backup(): Mark the .glom file as a backup file.
	Rename recreate_database() to recreate_database_from_example().
	on_document_load(): Handle backup .glom files similarly to examples files,
	but using the backup file instead of example data.
	* glom/frame_glom.cc:
	* glom/libglom/connection_pool.[h|cc]:
	* glom/libglom/connectionpool_backends/backend.[h|cc]: startup(): Return a
	StartupErrors enum, to provide more clues, for instance to say that backup
	data was found.
	Add get/set_database_directory_uri(), replacing the one in sqlite.[h|cc] and
	replacing set_self_hosting_data_uri() in postgres_self.[hc|cc].
	save_backup(): Don't take a filepath - use get_database_directory_uri()
	instead.
	Added convert_backup() to restore from a backup.
	* glom/libglom/connectionpool_backends/sqlite.[h|cc]:
	* glom/libglom/connectionpool_backends/postgres.[h|cc]:
	get_path_to_postgres_executable(): Catch exceptions from Glib::build_filename().
	save_backup(): Use --format=c with pg_dump, because the default one can't be
	used with pg_restore.
	Implement convert_backup(), using pg_restore.
	Added get_self_hosting_config_path(), get_self_hosting_data_path() and
	get_self_hosting_backup_path() to avoid copy/pasting magic paths.
	* glom/libglom/connectionpool_backends/postgres_self.[h|cc]:
	Adapted.
	* glom/application.[h|cc]:
	* tests/test_selfhosting_new_empty.cc: Adapted to check the enum result from
	startup().
