The first terminator is for input parameters. The second terminator was for the
output parameters.
If an error occurs when calling MakeThreadHighPriority(), e.g. a bad thread id,
then the reply from connection_send_with_reply_and_block() will be null.
Currently the message is double terminated, which results in SDL_DBus_CallMethodInternal()
incorrectly assuming that the other party is always returning true.
I'm not super familiar with dbus, so I'm not sure if this could also be the cause of this bug:

Add an include on SDL_error.h to avoid the following build failure
without threads:
/home/buildroot/autobuild/instance-0/output-1/host/opt/ext-toolchain/bin/../lib/gcc/arm-buildroot-linux-uclibcgnueabihf/8.3.0/../../../../arm-buildroot-linux-uclibcgnueabihf/bin/ld: build/.libs/SDL_threadprio.o: in function `SDL_LinuxSetThreadPriority_REAL':
SDL_threadprio.c:(.text+0x0): undefined reference to `SDL_Unsupported'

The SDL_USE_LIBDBUS define is set inside SDL_debug.h, therefore the
circular dependency made it impossible for this feature to be enabled.
Instead, guard SDL_dbus.h based on the autoconf variable HAVE_DBUS_DBUS_H
Additionally, fix one of the rtkit comments. CAP_SYS_NICE isn't required
to achieve high priority. But there is some scheduler config that rtkit
needs the app to setup.

There is an issue on the latest commit of the mercurial repo when SDL_THREADS_DISABLED is set:
src/core/linux/SDL_threadprio.c:79:28: error: unknown type name 'Sint64'; did you mean 'int'
