[PATCH] make fsck.minix smaller, fix English in messages

[Denis Vlasenko]

There are 9 patches to fsck.minix at http://195.66.192.167/linux/bbox/

The most complex one is minix7.patch, which combines minix v1 and
minix v2 handling, substantially reducing code size

Comments are at the top of each patch:



Fix bug (inode_map and zone_map are char* pointers)

* Do not initialize globals to 0, it is done automatically
* unsigned short -> uint16_t,  unsigned int -> uint32_t
  where appropriate (did it ever work on Alphas?)
* triple sync() is silly - removed
* check_zone_nr uses check_zone_nr2 now
* remove trailing periods from messages, uppercase first letter

Rework "current_name" hadling in preparation of
print_current_name() removal

Remove print_current_name()

Fix English in printf'ed messages

Reorganize #defines:
* delete unused ones
* convert integer ones into enum constants
* add SB_ prefix to values computed from superblock
* kill Super, use super_block directly

Remove code duplication due to minix v2

* Nuke PROGRAM_VERSION (it is never printed by stock fsck)
* static int IN sounds like #define, rename it

Remove some more unused #defines and the like



Testing of cumulative patches 1..9 was done with 4mb minix image
containing (part of) busybox source tree:

        # ./busybox.minix9 fsck.minix -lvf image >fsck_bb
        # fsck.minix -lvf image >fsck_std
        # diff -u fsck_bb fsck_std
