Update endspace.result now that InnoDB pads BLOBs properly with spaces in comparisons

  Fix that 'a' LIKE 'a%' was not true for an InnoDB BLOB or TEXT type column prefix index search: InnoDB assumed that the BLOB and TEXT should not be padded with space in comparisons; this bug is also in 4.1; it may have worked in 4.1 because MySQL may have asked there for strings >= 'a', while in 5.0 it asks for strings >= 'a        '

  Someone has fixed the calculation of length() for a returned InnoDB VARCHAR value: update endspace.result to have the correct value length('teststring') == 10

First one is related to Bug#7905. One should not be allowed to
create new user with password without UPDATE privilege to
MySQL database. Furthermore, executing the same GRANT statement
twice would actually crash the server and corrupt privilege database.

Other bug was that one could update a column, using the existing
value as basis to calculate the new value (e.g. UPDATE t1 SET a=a+1)
without SELECT privilege to the field (a in the above example)

Fixed tests grant.pl and grant2, which were wrong.

  Added a test for bug #8615.
sql_select.cc:
  Fixed bug #8615.
  This fix only removed the cause of the reported crash.
  It does not resolve other problems of rollup queries
  with DISTINCT. They were fixed in the previous patch 
  for bug 8616.

Enabled VARCHAR testing for innodb

NOTE: innodb.test currently fails becasue of a bug in InnoDB. 
I have informed Heikki about this and expect him to fix this ASAP

BUG#9123 is solved earlier than this patch though.

  Allow also long VARCHARs to be stored externally, not just BLOBs; fixes a bug reported by Trudy Pelzer; needs more testing

Now they always result a non NULL value even
the argument is NULL. It is more usefull for 
debugging purposes.
