make -j 8 check was sporadically failing in different xi2 tests. After adding the asserts in the previous commit to catch xkb failure it became easier to catch the failures and see that multiple tests were running at once trying to write to /tmp/server-(null).xkm and then delete it, and interfering with each other. Putting a unique string into the display variable let them each write to their own file and not interfere with others. v2: Fix Linux bits: Add #include <errno.h> to get a declaration of program_invocation_name on Linux. Use only the last portion of the pathname so that the resulting display name doesn't contain any slashes. v3: use program_invocation_short_name on Linux This is the same as program_invocation_name, except is has stripped off any path prefix.
