If the goa helper fails to find goa helper executable (which happened when run
without install), %NULL is returned. Avoid feeding g_variant_parse(), the %NULL
variable in those case as it is not nullable and avoid the crash that follows.
This is a massive rewrite of the panel. Because we can't have
nice things and WebKit2GTK for GTK4 won't be ready in time,
rework the panel to spawn a new subprocess with a dialog that
handles online accounts - both creation and editing.
Instead of having the "more" button which reveals more items to the
providers list.
We still list branded providers above non-branded providers in the
list.
Fixes#1072
Due to an API bug in GNOME Online Accounts, the asynchronous
goa_provider_get_all method doesn't accept a GCancellable argument. This makes
it difficult to cancel an ongoing call when the CcGoaPanel gets destroyed.
This was hacked around by taking a reference on the panel for the duration of
the call. Instead of cancelling a pending call on destruction, it would keep the
panel alive until the call was over.
The hack does not consider the case get_all_providers_cb is called while the
panel is still being initialized. E.g. this happen when create the panel passing
the paramenters "add <provider>" because the constuct properties are set just
after cc_goa_panel_init returns and because goa_provider_add_account will result
in a call to g_main_context_iterate (caused by gtk_dialog_run).
In order to work around this we can call goa_provider_get_all in _constructed()
after all construct properties have been set.

Due to an API bug in GNOME Online Accounts, the asynchronous
goa_provider_get_all method doesn't accept a GCancellable argument.
This makes it difficult to cancel an ongoing call when the CcGoaPanel
gets destroyed.
Prior to commit c26f8ae018, this was hacked around by taking a
reference on the panel for the duration of the call. Instead of
cancelling a pending call on destruction, it would keep the panel alive
until the call was over. However, that was lost during commit
c26f8ae018.
One thing to bear in mind is that GtkWidgets, CcGoaPanel is one, can
be destroyed by a gtk_widget_destroy call, which is subtly different
than a simple sequence of g_object_unref calls. When gtk_widget_destroy
is used, it invokes the GObject::dispose virtual method of the widget.
It is expected this will cause anything holding a reference to this
widget to drop their references, leading to GObject::finalize being
called. However, there is no guarantee that this will happen in the
same iteration of the GMainLoop. Therefore, it is possible that when
the goa_provider_get_all call finishes, the CcGoaPanel might be in a
disposed, but not yet finalized state.
When a GObject is in a disposed-but-not-finalized state, only a very
limited number of operations can be performed on it. Its reference
count can be altered, the memory used by the instance struct can be
accessed, but none of the member GObjects can be assumed to be valid.
eg., it's definitely illegal to add new rows to the member GtkListBox.
Hence a boolean flag is used to mark the destroyed state of the panel.
This second part is a small improvement over the earlier hack.

When removing an online account, gnome-control-center gives the user
the possibility to undo the action showing an "undo notification".
Right now if you close the gnome-control-center window, without dismissing
the notification, the online account will not be properly removed.

It's been more than four years and nobody ended up using this feature.
However, the extra cookie management that's necessary to implement this
feature has now exposed code, which people actually use, to a
WebKitGTK+ bug that's taking quite some time to be fixed. Therefore,
this is a good an excuse as any to remove this code.
This reverts commit 8762e2f8dchttps://bugzilla.gnome.org/show_bug.cgi?id=789469
The Online Accounts panel supports two commands: 'add'
and 'show-account'. The 'add' command must receive an
additional parameter, the 'provider' name, and an
optional 'preseed' parameter.
In the past, Settings would just push all the parameters
to a GVariant and pass to the panels. Now, however, it
skips the first one, making the parameter parsing code
in Online Accounts panel wrong.
This patch fix that by refactoring add_account() code,
and fixing the GVariant parameter parsing.
The panel owns both the GtkDialog, and the GoaProvider that is used
with the dialog during goa_provider_add_account. When the panel is
destroyed, it drops its references to the provider but not the dialog,
which is a separate top-level widget. Therefore, if the panel is
switched while the WebKitWebView inside the dialog was still
navigating across pages, then WebKitWebView::decide-policy will be
called with an invalid provider.
To avoid this, and a memory leak, the panel should also destroy the
dialog when it is itself getting destructed.
Note that since the GtkDialog is a template child, it must be
destroyed in dispose. GtkWidget's (ie. the panel's) default default
destroy signal handler NULLifies all template children pointers, so
finalize is too late.

When the user has no account set, the current implementation of the
Online Accounts panel shows a weird 1px line that is the empty list.
Fix that by only showing the list when there are accounts available.
https://bugzilla.gnome.org/show_bug.cgi?id=774222
We have different variants of the same code that iterates over all the
rows in a GtkListBox to find the one that corresponds to a given
account. Some action is then performed on the row, depending on the use
case at hand. In future we might want to look at the other rows in the
list to decide whether to hide the entire GtkFrame or not.
Let's consolidate this to reduce some duplication.

This will make the subsequent commits easier to read.
We are going to change get_row_for_account to be more generic. Moving
this code higher up will let us use it from a few more call sites.

When offline, we currently block the new accounts listbox
so that users can't add new accounts. There is, however,
no visual indication that we're offline, besides the listbox.
Fix that by adding a descriptive label that's only visible
when offline.

When adding and editing accounts, the different options that Online
Accounts provides may require different sizes of the dialog. There is,
however, a specific issue where the dialog can't resize because a
provider widget is interefering with the others.
Fix that by making the dialog's stack non-homogeneous, and making sure
to always reset the dialog size before showing it.

Following the previous commit, this commit effectively brings
back the account removal feature that was temporarily removed
by 4e197b491f.
This is now reimplemented as an in-app notification, and users
now have the option to undo an accidentally removed account.

When adding an account, the old proccess was: use the (removed) toolbar
to open the New Account dialog, select a provider in that dialog, add
the account and see the newly created account in the panel itself.
That approach had issues, e.g. the user would have to close the dialog
if she mistakenly selected a provider. After moving the provider list
to the panel itself, it doesn't make sense anymore to have another
provider list inside the dialog.
Fix this by moving the new account view to the accounts dialog.

This commit starts moving the contents of the add account dialog
class to the panel itself, by adding a providers listbox below
the list of available account as per the new mockups. As a side effect,
this commit temporarily makes removing an account non-functional.
The next commits are focused on finishing this move and removing
the add account dialog.

Instead of selecting an account, this commit makes the account
editor dialog only visible through explicit activation of the
account row.

We want to check the IsLocked property whenever we call
show_page_account. ie. when we show an account for the first time, and
also when the displayed account emits account-changed. Hence it is
better to have them together.

Following the mockups, the Online Accounts panel shall use a modal
dialog to edit online accounts.
This commit moves the current widgets to a dialog, and shows this
dialog whenever an account is selected.
