jdolecek 07fd899a7f Add new CLUST_END and use it as parameter to pcbmap() when searching
for end cluster, instead of explicitly passing 0xffff. This fixes potential
problem for FAT32, where cluster number may be legally bigger than 0xffff.

Also change clusteralloc() so that fillwith is not explicitly passed by caller
anymore (there is no need to use anything other than CLUST_EOFE).

jdolecek e2698cd72a Fix definition of MSDOSFSEOF(), which got broken in rev. 1.13.
It's shape is a bit different now than it was in rev 1.12, but is functionally
equivalent. Also add a comment explaining it's sense.

This fixes breakage reported after LP64 fixes in kern/8037, and
also kern/9116 and kern/9206.

leo 85ea3b1702 Instead of using '#ifdef atari' to handle the differences of Gemdosfs and
Msdosfs, use a flag that can be set by mount_msdos. This is definitely
more flexible.

leo 891ce379fd Make the msdosfs driver understand Atari-gemdos filesystems. Although they
have much in common, there are some differences in the bpb/bootsector that
needed to be handled in the mounting code. The gemdos bpb/bootsector structs
are included for clarification.

mycroft ae583dca34 Various changes:
* Make some of the code look more like UFS.
* Check permissions in lookup().
* Move the directory size special case into DE_EXTERNALIZE().
* Fix some conditions where lookup() might not release a buffer.
* Remove bogus flag handling in setattr().
* Pass timespec, not timeval, to deupdat().
* Check more error conditions.
* Fix possible panics in rename().
* Simplify readdir().
* General code cleanup; add prototypes, delete unused variables, etc.

cgd 54eb3b1f88 brought in fixed/renamed/matching MS-DOS FS code, from Jeff Polk
<polk@bsdi.com>.  His notes are as follows:
------------------------------------------------------------------------------

 July 22, 1993

 - Changed name of entire package from PCFS to MSDOSFS

 - Fixed bugs:
      root directory size in clusters instead of bytes
      growing directory didn't update in-core size
      link, symlink, mknod didn't free locked parent (deadlock)
      lookup returned real error on create and rename instead of EJUSTRETURN
      rename changed `.' entry in child instead of name entry in parent
      rename removed `.' entry in child instead of removing entry in
              parent when moving a directory from one dir to another
      createde() left new node locked when write of parent failed (deadlock)
      removede() decremented refcount even on error (rmdir's which failed
              due to write errors left in-core cache entries inconsistent)
      changed validation for filesystem to not check for the boot signature
              since some disks (e.g., mtools) aren't bootable
      directories are always show current time as modify time
              (needed for NFS export since DOS never updates dir mod times --
               ctime is true create time).

 - Added support for cookies changes to the readdir() vnode
      interface (#ifdef __bsdi__)

 - Punted on the whole problem of inode generation numbers.  This means
   that there's a chance of using a stale file handle to access a new
   file, but it doesn't appear to be the common case, and I don't see
   how to generate reasonable generation numbers without changing something
   on the disk (which is the way the SVR4 filesystem survival kit guys
   did it).  I don't think it would be very safe to change the on-disk
   format.
