Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!

+ * There are three possible formats:
+ *
+ * MODULE_FORMAT_BRIEF is the brief 6-character format, including
+ * the actual brick-type as recorded in the
+ * moduleid_t, eg. 002c15 for a C-brick, or
+ * 101#17 for a PX-brick.
+ *
+ * MODULE_FORMAT_LONG is the hwgraph format, eg. rack/002/bay/15
+ * of rack/101/bay/17 (note that the brick
+ * type does not appear in this format).
+ *
+ * MODULE_FORMAT_LCD is like MODULE_FORMAT_BRIEF, except that it
+ * ensures that the module id provided appears
+ * exactly as it would on the LCD display of
+ * the corresponding brick, eg. still 002c15
+ * for a C-brick, but 101p17 for a PX-brick.
+ *
+ * maule (9/13/04): Removed top-level check for (fmt == MODULE_FORMAT_LCD)
+ * making MODULE_FORMAT_LCD equivalent to MODULE_FORMAT_BRIEF. It was
+ * decided that all callers should assume the returned string should be what
+ * is displayed on the brick L1 LCD.
