Currently gpiocli does not display the libgpiod API version in the
output of gpiocli --version because it's not linked against libgpiod -
it's only a consumer of the DBus API.
However, with the recent changes to the versioning scheme and the
disassociation of the core C API from the libgpiod package version, it
now makes sense to display the latter so add it.

The org.freedesktop.DBus.Peer.Ping() method isn't correct for checking
if a given object is exposed by a service. It only lets us know if the
service is available no matter the object on which it's called (in fact:
it will not return an error even if it's called on a nonexistent object).
While this has worked for most part by accident, if the timing isn't
right, we may start calling methods in chips which are not yet fully
registered. We should try to read the chip's property instead and keep
on waiting for as long as org.freedesktop.DBus.Properties.Get() returns
an error.
While at it: fix the counter increment as its syntax is invalid.

When passing -v/--version to gpiocli or gpio-manager, it's useful to
also know the version of the GPIO D-Bus API the program implements.
Define the version in the gpiodbus.h header and print it together with
the library version.

Several data and test files were not included in distro tarballs so add
"dist_" automake variable prefixes where required.

Use G_GUINT64_FORMAT whenever printing 64-bit types to avoid format
specifier warnings.

On 32-bit architectures the size of a gulong will typically be 4 bytes
while we try to package an 8-byte integer when creating the edge event
variant. The client also expects wrong types and crashes. Use strict
type sizes for sending the events.
