patch so that it can later be compared with patchs with expanded symlinks 

The new --secure-file-priv checks dereference any symlinks in the paths and compare the 
resolved paths.
Thus the 5.0 test suite must do as the 5.1 and up and avoid using symlinks.

The query was re-written *after* we had tagged it with NON_AGG_FIELD_USED.
Remove the flag before continuing.

Backport of the fix to 5.0 (to be null-merged to 5.1).
Moved the test into the main test suite. 
Made mysql-test-run.pl to not use symlinks for sdtdata as the symlinks
are now properly recognized by secure_file_priv.
Made sure the paths in load_file(), LOAD DATA and SELECT .. INTO OUTFILE 
that are checked against secure_file_priv in a correct way similarly to 5.1 
by the extended is_secure_file_path() backport before the comparison.
Added an extensive test with all the variants of upper/lower case, 
slash/backslash and case sensitivity.
Added few comments to the code.

The 5.0 fix. Removed unreferenced files and the directory 
that has them.

             DEFINITION OF ANY ROUTINE.

This follow-up patch removes SHOW PROCEDURE CODE from the test
case as this command is only available on debug versions of the
server and therefore caused the test to fail on release builds.

             DEFINITION OF ANY ROUTINE.

The problem was that having the SELECT privilege any column of the
mysql.proc table by mistake allowed the user to see the definition
of all routines (using SHOW CREATE PROCEDURE/FUNCTION and SHOW
PROCEDURE/FUNCTION CODE).

This patch fixes the problem by making sure that those commands
are only allowed if the user has the SELECT privilege on the
mysql.proc table itself.

Test case added to sp-security.test.

Didn't build on Solaris.

The LGPL license is used in some legacy code, and to
adhere to current licensing polity, we remove those
files that are no longer used, and reorganize the
remaining LGPL code so it will be GPL licensed from
now on.

Note:  This patch only removed LGPL licensed files
       in MySQL 5.0, and is the first of a set of
       patches to remove LGPL from all trees.

privileges".

The first problem was that DROP USER didn't properly remove privileges 
on stored functions from in-memory structures. So the dropped user
could have called stored functions on which he had privileges before
being dropped while his connection was still around.
Even worse if a new user with the same name was created he would
inherit privileges on stored functions from the dropped user.
Similar thing happened with old user name and function privileges
during RENAME USER.

This problem stemmed from the fact that the handle_grant_data() function
which handled DROP/RENAME USER didn't take any measures to update
in-memory hash with information about function privileges after
updating them on disk.

This patch solves this problem by adding code doing just that.

The second problem was that RENAME USER didn't properly update in-memory
structures describing table-level privileges and privileges on stored 
procedures. As result such privileges could have been lost after a rename
(i.e. not associated with the new name of user) and inherited by a new
user with the same name as the old name of the original user.

This problem was caused by code handling RENAME USER in
handle_grant_struct() which [sic!]:
a) tried to update wrong (tables) hash when updating stored procedure
   privileges for new user name.
b) passed wrong arguments to function performing the hash update and
   didn't take into account the way in which such update could have
   changed the order of the hash elements.

This patch solves this problem by ensuring that a) the correct hash
is updated, b) correct arguments are used for the hash_update()
function and c) we take into account possible changes in the order
of hash elements.

sql/sql_acl.cc:
  Changed handle_grant_data() to also update hash with function 
  privileges. This allows DROP/RENAME USER correctly keep this 
  in-memory structure up-to-date.
  
  To do this extended handle_grant_struct() to support updating of this
  hash. In addition fixed code in this function which is responsible for 
  handling of column and routine hashes during RENAME USER, ensured that
  we correctly update these hashes after changing user name and that we
  don't skip elements while iterating through the hash and doing updates.
