unknown 99c431db92 Completion of merge of mysql-5.1 into mysql-maria.
Manually imported changes done to MyISAM (include/myisam.h,
storage/myisam/*, sql/ha_myisam.*, mysql-test/t/myisam.test,
mysql-test/t/ps_2myisam.test) the last
months into Maria (tedious, should do it more frequently in the
future), including those not done at the previous 5.1->Maria merge
(please in the future don't forget to apply MyISAM changes to Maria
when you merge 5.1 into Maria).
Note: I didn't try to import anything which could be MyISAM-related
in other tests of mysql-test (I didn't want to dig in all csets),
but as QA is working to make most tests re-usable for other engines
(Falcon), it is likely that we'll benefit from this and just have
to set engine=Maria somewhere to run those tests on Maria.
func_group and partition tests fail but they already do in main 5.1
on my machine. No Valgrind error in t/*maria*.test.
Monty: please see the commit comment of maria.result and check.

  fix for the new way of enabling engines
include/maria.h:
  importing changes done to MyISAM the last months into Maria
include/my_handler.h:
  importing changes done to MyISAM the last months into Maria
include/myisam.h:
  importing changes done to MyISAM the last months into Maria
mysql-test/r/maria.result:
  identical to myisam.result, except the engine name in some places
  AND in the line testing key_block_size=1000000000000000000:
  Maria gives a key block size of 8192 while MyISAM gives 4096;
  is it explainable by the difference between MARIA_KEY_BLOCK_LENGTH
  and the same constant in MyISAM? Monty?
mysql-test/r/ps_maria.result:
  identical to ps_2myisam.result (except the engine name in some places)
mysql-test/t/maria.test:
  instead of engine=maria everywhere, I use @@storage_engine (reduces
  the diff with myisam.test).
