This works whether `BUILD_LIBSYSTEMD` is `ON` or the separate build of
libsystemd picked up by pkg-config is static. The Gentoo Linux package
requires the latter.
This change also handles `BUILD_SHARED_LIBS` being `OFF`. In this case,
the libsystemd dependency does need to be included, even though it is
static.
CMake does not allow you to build shared and static libraries
simultaneously (with a single `add_library` call), but this change
declares the libsystemd dependency as `Requires.private` rather than
omitting it entirely. This is in case someone builds and installs both a
static and shared build and then calls `pkg-config --static sdbus-c++`.
The static build needs to be installed first so that the pkg-config
file from the shared build takes precedence.
* Add methods to initiate custom session bus connection
The new function helper `createSessionBusConnectionWithAddress` allows to create connection to session bus with custom address.

* Since ObjectPath and Signature have a user-declared copy-ctor and copy
assignment operator the implicit declaration of corresponding move
operations is disabled. Explicitly add defaulted versions so that
move operations actually move instead of copy.
* See: https://github.com/Kistler-Group/sdbus-cpp/issues/230
fix timeout handling
* Despite what is documented in sd_bus_get_timeout(3), the timeout
returned is actually an absolute time point of Linux's CLOCK_MONOTONIC
clock. Hence, we first have to subtract the current time from the
timeout in order to get a relative time that can be passed to poll.
* For async call timeouts to reliably work, we need a way to notify the
event loop of a connection that is currently blocked waiting in poll.
I.e. assume the event loop thread entered poll with a timeout set to
T1. Afterwards, the main thread starts an async call C with a timeout
T2 < T1. In order for C to be canceled after its timeout T1 has
elapsed, we have to be able to notify the event loop so that it can
update its poll data.

Allow to use human readable chrono literals to specify method call
timeout. The change is backward compatbile - if no unit is provided,
the fallback is "us".
Example:
<annotation name="org.freedesktop.DBus.Method.Timeout" value="500ms"/>
If -DBUILD_TESTS=ON, then creating debian packages fails
because dpkg-shlibdeps obiously can't find the sdbus-c++ dependency
for the tests package.
We could disable CPACK_DEBIAN_PACKAGE_SHLIBDEPS for the tests package.
Nevertheless I don't think we want a tests package at all.
Even though they have the same value, they are something fundamentally different.
Therefore it is extremely confusing if the constant INTERFACE_NAME is passed
where actually a well-known BUS_NAME (destination) should go.
