<AWT Dev> RFR: 8027912: [macosx] Provide means to force the headful mode on OS X when running via ssh

[David DeHaven]

Quick fix to reenable some automated testing that was broken by my recent fix to disable the X11 toolkit.

 int isInAquaSession() {
+    // environment variable to bypass the aqua session check
+    char *ev = getenv("AWT_FORCE_HEADFUL");
+    if (ev && (strncasecmp(ev, "true", 4) == 0)) {
+        // if "true" then tell the caller we're in an Aqua session without actually checking
+        return 1;
+    }
     // Is the WindowServer available?
     SecuritySessionId session_id;

Quick sanity check over a SSH session (where isInAquaSession was returning false):
