Subject: Bug#31210 - INSERT DELAYED crashes server when used on            
 partitioned table

Trying INSERT DELAYED on a partitioned table, that has not been
used right before, crashes the server. When a table is used for
select or update, it is kept open for some time. This period I
mean with "right before".

Information about partitioning of a table is stored in form of
a string in the .frm file. Parsing of this string requires a
correctly set up lexical analyzer (lex). The partitioning code
uses a new temporary instance of a lex. But it does still refer
to the previously active lex. The delayd insert thread does not
initialize its lex though...

Added initialization for thd->lex before open table in the delayed
thread and at all other places where it is necessary to call
lex_start() if all tables would be partitioned and need to parse
the .frm file.
