/* Examine 'path' recursively as follows:
 *

 *
 *   o Ask the filesystem for files and directories within 'path'
 *     (via scandir and stored in fs_entries)
 *
 *   o Pass 1: For each directory in fs_entries, recursively call into
 *     this same function.
 *
 *   o Compare fs_mtime to db_mtime. If they are equivalent, terminate
 *     the algorithm at this point, (this directory has not been
 *     updated in the filesystem since the last database scan of PASS
 *     2).
 *
 *   o Ask the database for files and directories within 'path'
 *     (db_files and db_subdirs)
 *
 *   o Pass 2: Walk fs_entries simultaneously with db_files and
 *     db_subdirs. Look for one of three interesting cases:
 *
 *	   1. Regular file in fs_entries and not in db_files
 *            This is a new file to add_message into the database.
 *
 *         2. Filename in db_files not in fs_entries.
 *            This is a file that has been removed from the mail store.
 *
 *         3. Directory in db_subdirs not in fs_entries
 *            This is a directory that has been removed from the mail store.
 *
 *     Note that the addition of a directory is not interesting here,
 *     since that will have been taken care of in pass 1. Also, we
 *     don't immediately act on file/directory removal since we must
 *     ensure that in the case of a rename that the new filename is
 *     added before the old filename is removed, (so that no
 *     information is lost from the database).
 *
 *   o Tell the database to update its time of 'path' to 'fs_mtime'
 *     if fs_mtime isn't the current wall-clock time.
