Use XPM as icon test output format.
The output of this test program is very close to XPM format.
So why not make it actually produce XPM format. This gives
us a good way to have it output actual colour icons too.

Allow compilation without X11.
At the moment this means nothing useful gets installed, but "make check"
is possible. The icon functions being tested don't _really_ depend on
X11, just the XColor structure for which we can supply a suitable
definition.

Fix boardmove testcase typo.
Comparing "if (argv > 0)" is an obvious typo, totally invalid and bogus.
Weirdly GCC fails to complain without "-pedantic", but HP-UX cc is happy
to inform us about the error.
