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.

"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.
