Like the original minix mkfs, add the -1 and -2 argument options to specify the
version of the filesystem to create.

Because of the dependence of fs_version, some superblock attributes will vary,
so simplify the logic of assigning values to maxsize and the amount of zones
related to each filesystem, thus making setup_tables() more readable.

Get rid of this function and use errx(3) instead. This patch also
introduces a mkfs.h header and defines general purpose mkfs related
exit codes.

This patch provides some minor code fixes: add/remove some macros and close the device after usage.
Also modifies usage() and changes main()'s indentation to 8-characters.

This bug has been introduced by commit
95356e8b74.
The fsck.minix code assumes that isset() macro returns boolean,
unfortunately the generic implementation from libc returns integer.
This patch also add a fallback for the bitmap macros to include/bitops.h.

This patch renames bitops.h to minix_bitops.h to avoid possible
collisions with global include/bitops.h file.

blkdev_get_size returns size in bytes, so BLOCKS has to be
calculated accordingly.
Use stat value for size if device is not a block device.

Minix filesystem until version 2 has a fixed blocksize of 1024 bytes.
If you try to create a filsystem on a device with a physical sectorsize
larger than 1024 bytes, this resulting minix fs cannot be mounted,
because the physical sectorsize must be smaller than the filesystem
blocksize.
This patch adds a check for this and will refuse to create a filesystem
if the sectorsize is bigger than the blocksize.

Let mkswap, mkfs.bfs, mkfs.minix open with O_EXCL if
used on block devices to prevent writing to the device
even if they are busy (mounted).
Unfortunately, O_EXCL has zero effect for 2.4 kernels where
in-kernel code doesn't use O_EXCL-like access locks. (Tested
on RHEL3.)
