Given that mk_genenum already parses FprintError, add the nick metadata
to the errors so that it matches the wanted DBus error and automatically
generate the errors list.
In this way we'll have to only touch one definition to get everything
updated
Fprintd is dependent on the deprecated dbus-glib, also this doesn't provide
various features we can take advantage of, like the ones for async
authentication mechanism.
So, remove all the dbus-glib dependencies and simplify the code, but without
any further refactor, and keeping everything as it used to work, while this
will give room for further improvements in subsequent commits.
Internally, we just use dbus-codegen to generate the skeletons, and we
use the generated FprintdDBusManager with composition, while we
implement the device skeleton interface in FprintDevice, so that we
don't have to use it as a proxy, and keep being closer to what it used
to be with dbus-glib.
Fixes: #61
There's no need to declare it as extern in the header as it is already
declared in the source files where it's used.
Fixes:
../src/device.c:51:25: error: redundant redeclaration of ‘fprintd_dbus_conn’ [-Werror=redundant-decls]

Mark all the methods on the device as async, so we
can get access to the associated DBusGMethodInvocation.
When claiming the device, remember the sender, and for every
API entry point, check that the sender is the same as the one
that made the original claim.
Trying to enroll a user whilst the device is already claimed
from another program will fail with:
** ERROR **: failed to claim device: Device was already claimed
This is the first step towards PolicyKit and multi-user support
Make all of FPrintManager's struct members private,
warn of errors using a _get_error() function, as object
creation can never fail.
The only error possible shouldn't really be an error though,
as it only means that no devices will be enumerated, but it
could tell us about newly plugged devices instead.
