review to branch (2010-01-04 to 2010-01-05) v222

• pairSearchRange can yield many items that are completely out of the window. Exclude those from tg->items so they don't inflate the item count and scare us off of making map links.
  • src/hg/hgTracks/bamTrack.c 1.22 - lines changed: 2, context: html, text, full: html, text
• Make empty directory appear to be non-existent, so udcFuse doesn't get confused by an empty dir becoming a regular file (i.e. udcCache dir with bitmap and sparseData).
  • src/fuse/udcFuse/udcFuse.c 1.7 - lines changed: 42, context: html, text, full: html, text
