- Use "mysql_stmt_field_count" to determine if there is a need to
call "mysql_stmt_store_result"


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

 - Execute "exec" commands directly with cmd.exe and replace "--exec echo ..." with "--exec .\echo.exe ..." 


client/mysqltest.c:
  Workaround the problem with "echo" in windows not behaving like "echo" in Unix.
  - Replace "--exec echo ..." with "--exec <path to mysqltest>\echo.exe" thus forcing
    use of our own echo implementation which baheves like on Unix.
  - The above change makes it possible to remove the need to execute all --exec's
    inside cygwin. Add ifdefs to only use use cygwin's bash conditionally

ENUMs weren't allowed to have character 0xff, a perfectly good character in some locales.
This was circumvented by mapping 0xff in ENUMs to ',', thereby prevent actual commas from
being used. Now if 0xff makes an appearance, we find a character not used in the enum and
use that as a separator. If no such character exists, we throw an error.

Any solution would have broken some sort of existing behaviour. This solution should
serve both fractions (those with 0xff and those with ',' in their enums), but
WILL REQUIRE A DUMP/RESTORE CYCLE FROM THOSE WITH 0xff IN THEIR ENUMS. :-/
That is, mysqldump with their current server, and restore when upgrading to one with
this patch.

sql/unireg.cc:
  Bug#24660: "enum" field type definition problem
  
  Use a field-separator for ENUM-values that is not part of those values. If impossible,
  throw error.

"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.
