"update existingtable set anycolumn=nonexisting order by nonexisting" would crash
the server.

Though we would find the reference to a field, that doesn't mean we can then use
it to set some values.  It could be a reference to another field.  If it is NULL, 
don't try to use it to set values in the Item_field and instead return an error.

Over the previous patch, this signals an error at the location of the error, rather
than letting the subsequent deref signal it.


mysql-test/r/order_by.result:
  Verify that all permutations work.
mysql-test/t/order_by.test:
  Verify that all permutations work.
sql/item.cc:
  When the field is NULL, don't dereference it when we set_field().  
  Instead, raise an error.

    - test* targets are identical (as much as possible) to 5.0 & 5.1 versions
    - use @PERL@ ./mysql-test-run.pl, instead of depending on /usr/bin/perl location
    - PHONY: target includes all test targets


Makefile.am:
  - test* targets are identical (as much as possible) to 5.0 & 5.1 versions
  - use @PERL@ ./mysql-test-run.pl, instead of depending on /usr/bin/perl location
  - PHONY: target includes all test targets

mysql-test/t/kill.test:
  Move the connect of second connection to just before the query to be killed are sent.
  This introduces less variance since the connect time is not included in the delay
  we want between send of query and kill.

 - Use "mysql_field_count" to determine if there is a need to
   call "mysql_store_result"


client/mysqltest.c:
  Only call 'mysql_store_result' if 'mysql_field_count' is greater than 0
  indicating that this query has a result set.  This change is mainly since
  if mysql_store_result fails the value returned by mysql_field_count will be reset.

 - Thanks to Vasil Dimov for the patch!


client/mysqltest.c:
  Use my_snprintf to protect against exceeding size of buff
  Since variable name and valu might not be null terminated it's necessary to
  provide the length of the format specifiers.

- Using DATA/INDEX DIRECTORY option on Windows put data/index file into
  default directory because the OS doesn't support readlink().
- The procedure for changing data/index file directory is 
  different under Windows.
- With this fix we report a warning if DATA/INDEX option is used,
  but OS doesn't support readlink().


mysql-test/r/windows.result:
  - updated result file.
mysql-test/t/windows.test:
  - Added test case to verify we get warnings if we specify DATA/INDEX
    DIRECTORY on a platform which doesn't support readlink().
sql/sql_parse.cc:
  - Added warnings if DATA/INDEX DIRECTORY option is used but not supported
    by the target platform.
