- When cache memory can't be allocated size is recaclulated using 3/4 of
  the requested memory. This number is rounded up to the nearest 
  min_cache step. 
  However with the previous implementation the new cache size might
  become bigger than requested because of this rounding and thus we get
  an infinit loop.
- This patch fixes this problem by ensuring that the new cache size
  always will be smaller on the second and subsequent iterations until
  we reach min_cache.


mysys/mf_iocache.c:
  - Added mask to cachesize to ensure that algorithm always produce a 
    smaller cache size than current, until we reach 'min_cache' size.

mysql-test/mysql-test-run.pl:
  Pass "--no-defaults" to embedded server as "--server-arg=--no-defaults"

mysql-test/t/kill.test:
  Move the connect of second connection to just before the query to be killed are sent.
  This introduces less variance since the connect time is not included in the delay
  we want between send of query and kill.

 - Use "mysql_field_count" to determine if there is a need to
   call "mysql_store_result"


client/mysqltest.c:
  Only call 'mysql_store_result' if 'mysql_field_count' is greater than 0
  indicating that this query has a result set.  This change is mainly since
  if mysql_store_result fails the value returned by mysql_field_count will be reset.

 - Thanks to Vasil Dimov for the patch!


client/mysqltest.c:
  Use my_snprintf to protect against exceeding size of buff
  Since variable name and valu might not be null terminated it's necessary to
  provide the length of the format specifiers.

This error is displayed anytime the SELECT statement needs a temp table to
return correct results because the object (select_dumpvar) that represents
variables named in the INTO clause stored the results before the temp
table was considered.  The problem was fixed by creating the necessary
Item_func_set_user_var objects once the correct data is ready.

mysql-test/t/distinct.test:

  - Added various Selects that use the INTO statement and a temp table.
  - Added Select Into Outfile variant tests also.

  Bug#20836 Selecting into variables results in wrong results being returned
  - The select_dumpvar variable created a Item_func_set_user_var too early
  and once set, it was not possible to change.  The Item_func_set_user_var
  is now created once the final results are available.
sql/sql_class.h:
  Bug#20836 Selecting into variables results in wrong results being returned
