Simon McVittie 510d0716be gdbus: Use symbolic constants for the most common D-Bus error names
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.
