Setting read buffer to values greater than SSIZE_MAX results in
unexpected behavior.

According to read(2) manual:
If count is greater than SSIZE_MAX, the result is unspecified.

Set upper limit for read_buffer_size and read_rnd_buffer_size to
SSIZE_MAX.

CHECK TABLE did temporarily clear the auto_increment value.
It runs with a read lock, allowing other readers and
conurrent INSERTs. The latter could grab the wrong value
in this moment.

CHECK TABLE does no longer modify the auto_increment value.
Not even for a short moment.


myisam/mi_check.c:
  Bug#19604 - CHECK TABLE with concurrent INSERT can reset auto_increment
  In chk_key() and update_auto_increment_key() in the repair_only
  case, do not touch info->s->state.auto_increment. Especially
  chk_key() can be called from CHECK TABLE with a read lock.
  Concurrent inserts could grab a temporarily changed value.
  Added minor style fixes.
myisam/mi_key.c:
  Bug#19604 - CHECK TABLE with concurrent INSERT can reset auto_increment
  Changed update_auto_increment() to retrieve_auto_increment()
  to reflect that it does not change the auto_increment by
  itself any more. This must now be done externally if needed.
myisam/mi_update.c:
  Bug#19604 - CHECK TABLE with concurrent INSERT can reset auto_increment
  Added explicit update of info->s->state.auto_increment
  after the change from update_auto_increment() to
  retrieve_auto_increment().
myisam/mi_write.c:
  Bug#19604 - CHECK TABLE with concurrent INSERT can reset auto_increment
  Added explicit update of info->s->state.auto_increment
  after the change from update_auto_increment() to
  retrieve_auto_increment().

The order of acquiring LOCK_mysql_create_db
and wait_if_global_read_lock() was wrong. It could happen
that a thread held LOCK_mysql_create_db while waiting for
the global read lock to be released. The thread with the
global read lock could try to administrate a database too.
It would first try to lock LOCK_mysql_create_db and hang...

The check if the current thread has the global read lock
is done in wait_if_global_read_lock(), which could not be
reached because of the hang in LOCK_mysql_create_db.

Now I exchanged the order of acquiring LOCK_mysql_create_db
and wait_if_global_read_lock(). This makes 
wait_if_global_read_lock() fail with an error message for
the thread with the global read lock. No deadlock happens.

            SELECT WHERE a= AND b=

Selecting data from memory table with varchar column and hash index over it
returns only first row matched.

Problem was that key length calculation for varchar columns didn't include
number of bytes to store length.

Fixed key length for varchar fields to include number of bytes to store length.

A query with a group by and having clauses could return a wrong
result set if the having condition contained a constant conjunct 
evaluated to FALSE.
It happened because the pushdown condition for table with
grouping columns lost its constant conjuncts.
Pushdown conditions are always built by the function make_cond_for_table
that ignores constant conjuncts. This is apparently not correct when
constant false conjuncts are present.
