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

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,
