Theodore Ts'o 1b6bf1759a Many files:
pass*.c, super.c: Massive changes to avoid using printf and com_err
  	routines.  All diagnostic messages are now routed through the
  	fix_problem interface.
  pass2.c (check_dir_block): Check for duplicate '.' and '..' entries.
  problem.c, problem.h: Add new problem codes PR_2_DUP_DOT and
  	PR_2_DUP_DOT_DOT.
  problem.c: Added new problem codes for some of the superblock
  	corruption checks, and for the pass header messages.  ("Pass
  	1: xxxxx")
  util.c (print_resource_track): Now takes a description argument.
  super.c, unix.c, e2fsck.c: New files to separate out the
  	operating-specific operations out from e2fsck.c.  e2fsck.c now
  	contains the global e2fsck context management routines, and
  	super.c contains the "pass 0" initial validation of the
  	superblock and global block group descriptors.
  pass1.c, pass2.c, pass3.c, pass4.c, pass5.c, util.c: Eliminate
  	(nearly) all global variables and moved them to the e2fsck
  	context structure.
  problem.c, problem.h: Added new problem codes PR_0_SB_CORRUPT,
  	PR_0_FS_SIZE_WRONG, PR_0_NO_FRAGMENTS, PR_0_BLOCKS_PER_GROUP,
  	PR_0_FIRST_DATA_BLOCK
expect.1, expect.2:
  Updated tests to align with e2fsck problem.c changes.
