70823e1d91 MDEV-5120 Test suite test maria-no-logging fails 
The reason for the failure was a bug in an include file on debian that causes 'struct stat'
to have different sized depending on the environment.

This patch fixes so that we always include my_global.h or my_config.h before we include any other files.

Other things:
- Removed #include <my_global.h> in some include files; Better to always do this at the top level to have as few
  "always-include-this-file-first' files as possible.
- Removed usage of some include files that where already included by my_global.h or by other files.

ef4c0f68d1 Bug #30584: delete with order by and limit clauses does not 
use limit efficiently
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()).
