sd_bus_encode_many() escaps elements starting with a digit so our 0 profile
has an object path of /.../_30. This is quite confusing during debugging.

Lets use the new get_device_path() helper to allow calling show-device
without any argument. This follows what show-profile does already.

New verb: show-profile
This simply prints a profile of a given device by querying ratbagd for
all information on the selected profile.

Add a new property to profiles that exposes resolutions on the bus. We
simply expose a dictionary entry for each resolution, hence, we can
easily extend it in the future. However, we avoid the full overhead of
real dbus objects, as there is no real need for it.

Add two new helpers to query ratbagd for the object-paths of a specific
object:
GetDeviceByName: Return device given a device name
GetProfileByIndex: Return a profile given a profile index
Signed-off-by: David Herrmann <dh.herrmann@gmail.com>
We should always provide valid data if requested via Get().
Unfortunately, DBus still does not include 'maybe' types, so we just
return something that is clearly invalid data.

Two new verbs for ratbagctl:
- list-devices: list all available devices
- show-device: show detailed information about a single device

Expose a list of profiles, including a tag for the active profile, from
within each ratbagd device via DBus.

Never return information about non-existant profiles. Just skip NULL
profiles silently, when iterating.

Refrain from hierarchical paths and instead use object prefixes with
unique paths each. This avoids several nasty DBus-enforced behaviors
regarding deep hierarchies. Furthermore, it keeps the names shorter,
which is always a nice side-effect.

Provide two new profile accessors that return the path and index of a
profile. This also requires us to cache the dbus path in the profile
itself.

New helper to return the name of a device. This will be required to build
hierarchical paths in the sub-classes, like profiles.

Instead of relying on the cricket ObjectManager interface, use our own
manager interface. This gets rid of ridiculous recursive behavior of the
ObjectManager interface and instead allows us to control the behavior.

This is no longer needed. Use the device-iterator in ratbagd.c directly
and then drop ratbagd_device_list().

Add helper to retrieve the device path from outside of ratbagd-device.c.
This will be needed for the non-object-manager based enumerators and
signals introduced to org.freedesktop.ratbag1.Manager.

Profiles are static children of devices. Expose them as 2nd-level objects
underneath their parent devices on the bus.
Signed-off-by: David Herrmann <dh.herrmann@gmail.com>
Make sure the device management (lookup and enumeration and registration)
is done from the parent, not the child. Hence, move it into ratbagd.c over
ratbagd-device.

Make sure our dbus callbacks to not contain any logic themselves. They
should be simple wrappers around our internal object handling.
This also makes use of the new sd-bus pat helpers, to-be-released with
systemd-v227 next week.

This does not work, we cannot flag properties as UNPRIVILEGED. Drop it.
Lets figure out later what exactly we want as privilege level to

Make sure to create libratbag_device contexts for each device we add. If
libratbag returns NULL, we just ignore the devices. Otherwise, we keep
the context around and manage the device.
Signed-off-by: David Herrmann <dh.herrmann@gmail.com>
Make sure the ratbagd context has a reference to a valid libratbag
context at all times. We need this to access libratbag devices, so lets
reference on in our own context.
This also adds a dependency for libratbag via autotools.

Add safe_close() helper that makes close(2) a bit nicer to use. This also
introduces PROTECT_ERRNO, which makes sure a function does not clutter
errno if called.
Signed-off-by: David Herrmann <dh.herrmann@gmail.com>
This adds two new components:
1) ratbagd
The ratbagd daemon is a very basic dbus daemon that provides an
org.freedesktop.DBus.ObjectManager based enumeration and modification
API for libratbag devices. So far, all it does is enumerate input
devices on the bus. However, this will be extended to advertise full
libratbag hierarchies on the bus and allow clients to modify
properties via DBus.
So far, it is root-only, but the DBus policy can be losened and PolKit
support can be added.
2) ratbagctl
A very basic command-line tool to manage ratbagd. It's basically a
command-line interface for the DBus API of ratbagd.
So far, it has no hookup for anything. This will be added once ratbagd
gains further DBus APIs.
