New more SP-locking friendly approach to handling locks in multi-update.
Now we mark all tables of multi-update as needing write lock at parsing
stage and if possible downgrade lock at execution stage (For its work
SP-locking mechanism needs to know all lock types right after parsing
stage).

 - If number of records in table is 4, the calculated cost for using "index" and "range" become so close so that any rounding errors becomes visible.
 - Added one more record to the tables for heap test and expoect "range" to be selected
 - Decrease number of records in t1 for range and expect "index" to be choosen.

because config.status may later need this file (if it does not find it
it won't incorporate dependencies of errmsg.sys in sql/share/Makefile) (thx Serg).
In sql/share/Makefile.am using "all:" leads to double-"all:" in Makefile (thx Konstantin).

if we fall back to mysql_alter_table() (for InnoDB), don't do binlogging in mysql_alter_table(), as mysql_admin_table()
is not supposed to do any binlogging (it is done by the caller).

We should not cache queries using CURRENT_USER() function as we do it
for some other functions, e.g. USER() function.
