To avoid adding a large block of macros to gdbusprivate.h, I've only added a subset of the well-known error names. I chose to draw the line by adding constants for the errors emitted via their string names in GDBusConnection, but not for error names that are only mentioned in `gdbuserror.c` or in tests.
