When querying for the details of a particular user by their UID, we call
accountsservice over D-Bus. Its API takes a gint64 variant, which we
build using g_variant_new(), which takes varargs. Passing an integer of
type uid_t in the varargs works fine on 64-bit architectures, where
uid_t is 64-bit, but not on other architectures, where it’s likely
32-bit. In that case, g_variant_new() will still read 64 bits from the
varargs input, even though the caller only put 32 on there. The rest
will be filled with rubbish.
Fix that by explicitly casting the uid_t to gint64 in the varargs. Fix a
few other areas where uid_t variables are passed to functions which
might interpret them as a different kind of integer too.

That’s what’s more conventional for D-Bus properties, and we really
should have used CamelCase from the beginning.
See the advice on
https://dbus.freedesktop.org/doc/dbus-specification.html#standard-interfaces-properties:
> Strictly speaking, D-Bus property names are not required to follow
> the same naming restrictions as member names, but D-Bus property
> names that would not be valid member names (in particular,
> GObject-style dash-separated property names) can cause
> interoperability problems and should be avoided.

Since we ported to using FindUserById, it returns an explicit Failed
error if a user doesn’t exist. Previously, we would guess at the user’s
object path and call a method on it, and would receive a D-Bus ‘method
not found’ error in response if the user didn’t exist.
Correctly handle the explicit error from FindUserById.

This controls whether the user can install to their user repository at
all; if it’s true (the default), then installation of apps is still
subject to the OARS filter.

This is in preparation for adding a second boolean for the flatpak user
repository. Make the existing allow-app-installation boolean control
permissions for the flatpak system repository.
Having one boolean for each repository means we can allow users to
install to their user repository by default (subject to OARS ratings),
but not be allowed to install to the system repository.
While changing the name and semantics of the boolean, flip its default
value from True to False. Rather than letting any non-admin user install
new apps by default (subject to OARS restrictions), re-limit it to admin
users and users whose allow-system-installation key has been explicitly
set to True by the admin.

These are the app-specific part of a flatpak ref, and are what’s
available when you have a .desktop file, via the X-Flatpak key in the
.desktop file. For example, for a flatpak ref
‘app/org.gnome.Builder/x86_64/master’, the app ID is
‘org.gnome.Builder’. It makes sense that we’d want to match against app
IDs in some situations, since the user probably doesn’t care about the
architecture or branch of the app they want to proscribe.

This is a boolean preference which overrides the OARS values entirely if
FALSE.
This change breaks ABI for EpcAppFilterBuilder, but since that hasn’t
been used in any code we’ve shipped yet, that should be OK.

Instead of manually constructing the D-Bus object path representing a
user, call FindUserById to have accountsservice do it for us. For normal
users, this makes no difference. For system users (UID < 1000) or other
users which accountsservice considers uninteresting (see
user_classify_is_human() in user-classify.c in accountsservice), no
D-Bus objects are created for them automatically. Calling FindUserById
ensures that the object is created before its path is returned to us.

As well as handling paths on the file system, we should allow flatpak
refs to be explicitly handled in the app filter.
Both refs and paths can be stored safely in the same app filter GStrv
because paths are always absolute and refs always start with ‘app/’ or
‘runtime/’.
