ChangeLog, pass3.c, problem.c:

ChangeLog, pass3.c, problem.c:
  pass3.c (get_lost_and_found): If the filesystem is not opened
  	read-only, then force /lost+found to be created if it is not present.
  problem.c: Allow PR_3_NO_LF_DIR to be handled during a preen operation.
ChangeLog, Makefile.in:
  Makefile.in: Updated dependencies.
ChangeLog, fsck.c:
  fsck.c (load_fs_info): Parse /etc/fstab ourselves, instead of relying
  	on getmntent().  This has the advantage of allowing us to properly
  	handle missing pass numbers correctly.
ChangeLog, configure.in:
  configure.in: Add paths.h to header files for which we search.
