MDEV-3798: [SHOW] EXPLAIN UPDATE/DELETE, Memory leak in binlog.binlog_base64_flag:
- It turns out, there are statements that will call lex_start(thd->lex)
after parsing has been finished. lex_start() will set lex->explain=NULL,
which will lose the pointer to already allocated Explain_plan object.
- To get rid of this, switch to lazy creation of lex->explain. Now, it is
created only when we get a part ot query plan.
