Fixed BUG#9538: SProc: Creation fails if we try to SET system variable
using @@var_name in proc
Made sure we don't lose the tokenizer state when swapping lex in during SET
parsing.
mysql-test/r/sp.result:
New test case for BUG#9538.
mysql-test/t/sp.test:
New test case for BUG#9538.
sql/sp_head.cc:
Keep lex->next_state when swapping lex during SP parsing (for SET mainly),
otherwise the tokenizer gets confused.
