dir->name is now *char instead of char[256] to reduce memory footprint. Slight performance hit of 0.5% for index time, though. Changed ent_list buffer size to grow at power of two always
duc_dir entries in the database are now prepended with a header with parent dev/ino, total bytes, file count and dir count. This allows faster traverstal back into the tree because of access to the parent nodes, and allows for more statistics on a directory

Moved db functions into db.c
indenting
