This ensures the example can fit windows of any height.

This also makes the stack containing the content non vertically
homogeneous so the scrollbar appears only on examples needing it, while
keeping it horizontally homogeneous for to keep when the leaflets will
be folded consistent.

Since commit c5bf27d4 header bars are
destroyed before header group, so when destroying the header group, the
list of header bars is always empty, so there's nothing to unref anymore.

Reverts commit 14e5fc7b.

When adding a header bar, ref the header group and connect to 'destroy'
signal of the header bar. When a header bar is destroyed or
hdy_header_group_remove_header_bar() is called, unref the header bar and
remove it from the list.

This way, a non-empty header group is only destroyed after every header
bar it contains has been removed from the group or destroyed.

Fixes #56

The header bars might still emit signals which leads to

** (gnome-games:25525): CRITICAL **: 11:18:29.087: update_decoration_layouts: assertion 'HDY_IS_HEADER_GROUP (self)' failed

** (gnome-games:25525): CRITICAL **: 11:18:29.087: update_decoration_layouts: assertion 'HDY_IS_HEADER_GROUP (self)' failed

or actual crashes.

Fixes parts of #56

The dispose heandler is meant to break refs to other objects, not
finalize.

This allows to call the function from Vala more easily.

This adds a demo of HdySearchBar.

This is similar to GtkSearchBar except it allows the central widget
(typically a GtkEntry) to fill all the available space. This is needed
to manage an entry's width via a HdyColumn, letting the entry (and by
extention the search bar) have a limited maximum width while allowing it
to shrink to accomodate smaller windows.

Annotate the arguments of hdy_init() with (optional) to specify that
NULL arguments are valid. This also replaces the deprecated (allow-none)
by (nullable) to specify that the array pointed at by argv can be NULL.

clang-3.9 does not contain scan-build anymore.

This gives us more confidence that we build succesfully and without
warnings on an OS much used by GNOME developers.

It also makes sure we validate the spec file.

Document common practice in the other files.

Use @basename@ instead of @filename@ since the later uses the full
path which varies across builds.

Disable generation of the GObject Introspection files, the VAPI and the
tests in the example Flatpak as they are not used by it.

This standardizes the header inclusion guards to #pragma once, which
shouldn't be a problem as we already were using it in some files.

Rephrase the documentation explaining how to include libhandy in a way
that could include other languages such as Vala.

This will help the widgets to be more accessible.

This is needed to port to GTK+ 4 as these fields will be private.

Makes HdyDialer descend from GtkBin directly rather than from
GtkEventBox. GtkEventBox will be dropped in GTK+ 4 and brings no
functionality to HdyDialer.

This is e.g. not the case for Clang on OSX.

Closes: #58

This will avoid our users to manually ensure libhandy widget types are
loaded before using them in GtkBuilder templates.

Fixes Librem5/libhandy#20

We run in gitlab-ci now
