This switches from a raw pointer to std::optional type to pass prospective call errors to the client (using std::optional was not possible years back when sdbus-c++ was based on C++14). This makes the API a little clearer, safer, idiomatically more expressive, and removes potential confusion associated with raw pointers (like ownership, lifetime questions, etc.).
This makes D-Bus proxy signal registration more flexible, more dynamic, and less error-prone since no `finishRegistration()` call is needed. A proxy can register to a signal at any time during its lifetime, and can unregister freely by simply destroying the associated slot.

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"/>
- add a list of c++ keywords and common defines
- sanitize names so that there are no functions/args with names that are reserved in c++
