Changes in quota-package from 1.0 to 1.1

* Moved check to test on quota on a certain filesystem to seperate file
  hasquota.c

* Changed hasquota.c to use quotafile given in fstab file instead
  of the default name of a quotafile. We now can define ourself where
  to put our quotafile. Something like "usrquota=/usr/adm/quotasrc.user"

* Changed graceperiod counting was doing it the wrong way around. Now we
  add the expiretime to the current time and that is the grace-period a user
  has before we see a softlimit as a hardlimit.

* Changed allocation when not enough blocks can be allocated from ones quota.
  Now you get as many blocks as you can affort yourself and not as in the 
  earlier version, nothing. This was a bit of a bitch to tackle but it seems
  to work ok now for regular files and core-files.

* Changed the quota.h file to include a prototype for a new function
  blocks_to_isize that calculates the maximum isize for a file when allocating
  less blocks than requested. Also included macro's for min() and max().

* Added rquotad program for own convinience, this was build from scratch with
  only the rquota.x file. It seems to work quite nice between LINUX machines
  don't have the resources to test it with other then LINUX machines.
  We probably need a new version number for this type of rquota.
  Something like rquota version 2 or something like that.

* Changed quota program to use a rpc-call to the rquotad on one of you
  disk server machines. See #ifdef RPC in quota.c. Use small timeout because
  I don't wanna wait to long when a machine is down. Increase it when you have
  problems with slow hosts.

* Rewrite of quotacheck program. This one is much faster, about 60%. Thanks
  to Edvard for this big improvement.

* Merged files from quota-fs-dir into one file in the fs-dir named quota.c
  (By Fred N. van Kempen)

* Changed namei.c to iput the inode of a dir when doing a remove of a dir.
  I never had problems with it but it seems that ext2 doesn't care to much when
  you unlink a dir while you have the inode still open. Fixed it and it works
  now ok also on xiafs which had problems with it, and of course the fragment
  should have give this error because you have to iput the dir before you remove
  it.

* Changed source of quotacheck to create new quotafile with at least the
  gracetimes. Now there should never be a problem when turning on quota with
  the quotactl systemcall after one has run quotacheck to create the correct
  quotafiles.
  
* Changed code of quota.c to read MOUNTED(mtab) instead of FSTAB(fstab) when
  showing quotainfo.
