8abdc2eb40 Sweep through the tree fixing mmap() usage: 
- Use MAP_FAILED instead of the constant -1 to indicate
    failure (required by POSIX).
  - Removed flag arguments of '0' (required by POSIX).
  - Fixed code which expected an error return of 0.
  - Fixed code which thought any address with the high bit set
    was an error.
  - Check for failure where no checks were present.

7cb29d3394 This update adds the support for != 512 byte sector SCSI devices to 
the sd & od drivers. There is also slight changes to fdisk & newfs
in order to comply with different sectorsizes.
Currently sectors of size 512, 1024 & 2048 are supported, the only
restriction beeing in fdisk, which hunts for the sectorsize of
the device.
This is based on patches to od.c and the other system files by
John Gumb & Barry Scott, minor changes and the sd.c patches by
me.
There also exist some patches for the msdos filesys code, but I
havn't been able to test those (yet).

7f3b8ca95f Make the numbers for the "superblock backups" fit nicely on the screen, 
even for larger partitions.  Until now, partition sizes > 500 MB messed
up the screen.

a3189e21e6 Restrict fs_maxfilesize to 2^40; this is part of a bug fix from Kirk 
McKusick to work around problems in FFS related to the blkno of a 64bit
offset not fitting into an int.

72ab19aeb7 Added '-F file' option of mount_mfs. This allows me to make floppy images 
without waiting for my floppy-drive all the time :-)  Might have other
interesting uses too.

3156bbb2d1 Backed out part of the last change that prevents the rpos table from 
being output if <= 1 rpos; there is a bug in the kernel which doesn't
quite get along with this. Changed default #rpos to 1, and fixed up
manual page. Converted nrpos to 1 if user specifies 0.

7ce005d7c1 1) If nrpos <= 1, don't output rpos table (and set fs_cpc to 0) - disabling 
the use of the rotational position table.
2) Allow specification of 0 rotational positions (disables function).
3) Make rotdelay=0 and nrpos=0 by default.

   The purpose of the above is to optimize for modern SCSI (and IDE) drives
that do read-ahead/write-behind.
