notify UVM of the file's new size rather than in extendfile().

cgd db4b935691 passs FAT block mask as argument to MSDOSFSEOF(), so that fat.h is
more useful.

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).

cgd e9d17d38b5 avoid unnecessary aging of buffers. This used to make sense, when buffer
caches were much smaller, but makes little sense now, and will become more
useless as RAM (and buffer cache) sizes grow.  Suggested by Bob Baron.

* 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.

        Jeff Polk (polk@BSDI.COM)
