trees named after mysql-[trunk|next-mr] would not skip those tests.

Bug #36569: UPDATE ... WHERE ... ORDER BY... always does a
            filesort even if not required

Also two bugs reported after QA review (before the commit
of bugs above to public trees, no documentation needed):

Bug #53737: Performance regressions after applying patch
            for bug 36569
Bug #53742: UPDATEs have no effect after applying patch
            for bug 36569


Execution of single-table UPDATE and DELETE statements did not use the 
same optimizer as was used in the compilation of SELECT statements. 
Instead, it had an optimizer of its own that did not take into account 
that you can omit sorting by retrieving rows using an index.

Extra optimization has been added: when applicable, single-table 
UPDATE/DELETE statements use an existing index instead of filesort. A 
corresponding SELECT query would do the former.

Also handling of the DESC ordering expression has been added when
reverse index scan is applicable.

From now on most single table UPDATE and DELETE statements show the 
same disk access patterns as the corresponding SELECT query. We verify 
this by comparing the result of SHOW STATUS LIKE 'Sort%

Currently the get_index_for_order function 
a) checks quick select index (if any) for compatibility with the
   ORDER expression list or
b) chooses the cheapest available compatible index, but only if 
   the index scan is cheaper than filesort.
Second way is implemented by the new test_if_cheaper_ordering
function (extracted part the test_if_skip_sort_order()).

Fix syntax error (missing space in SET command),  that effectively prevents mysqld from being build with SSL.

Handle this warning in the future as error, this will prevent pushing to main trees.

InnoDB came in a new version "simultanously" with the
commit.  This patch is a minor change to the new innodb
regression test suite. 

The default storage engine is changed from MyISAM to
InnoDB, in all builds except for the embedded server.

In addition, the following system variables are 
changed:

  * innodb_file_per_table is enabled
  * innodb_strict_mode is enabled
  * innodb_file_format_name_update is changed
    to 'Barracuda'

The test suite is changed so that tests that do not
explicitly include the have_innodb.inc are run with
--default-storage-engine=MyISAM.  This is to ease the
transition, so that most regression tests are run
with the same engine as before.

Some tests are disabled for the embedded server
regression test, as the output of certain statements
will be different that for the regular server
(i.e SELECT @@default_storage_engine).  This is to
ease transition.

This is the fix for 5.5, where the behaviour on both installation
and upgrade is changed:
On installation, we do not start the server, to allow automated
installs (which happen in some indeterminate machine status).
If the server was stopped when the upgrade begins, we assume the
administrator is taking manual action, so we do not start the (new)
server at the end of the upgrade.
We still install the start/stop script, so it will be started on reboot.
