1) Handling string memory allocation with a new STRING class. This is only

   the beginning. Defining the STRING class and begining to use it (MYSQL)

2) Change the xtrace, use_tempfile and exact_info connect variables from
   GLOBAL to SESSION. Remaining GLOBAL variables have been made readonly.

3) Take care of LEX_STRING variables. The .str should not be regarded as
   allways being 0 terminated. This is handled by the Strz functions that
   make sure to return 0 terminated strings.

Bug fix:
- When inserting in MYSQL table with special column(s) a query such as:
insert into t2 values(0,4,'new04'),(0,5,'new05');
failed saying: column id (the special column) not found in t2.
It is now accepted but must be counted in values (these 0 are ignored)
- ROWID was returning row numbers based 0. Now it is from base 1.
