main.derived_cond_pushdown: Move all 10.3 tests to the end,
trim trailing white space, and add an "End of 10.3 tests" marker.
Add --sorted_result to tests where the ordering is not deterministic.
main.win_percentile: Add --sorted_result to tests where the
ordering is no longer deterministic.

The syntax error happened because we had not implemented a different print for
percentile functions. The syntax is a bit different when we use percentile functions
as window functions in comparision to normal window functions.
Implemented a seperate print function for percentile functions

Fixed by MDEV-15902, just added the test case for this issue.

Element_type& Bounds_checked_array<Element_type>::operator[]
(size_t) [with Element_type = Item*; size_t = long unsigned int]
In sql_yacc.yy the semantic actions for the MEDIAN window function
lacked a call of st_select_lex::prepare_add_window_spec().
This function saves the head of the thd->lex->order_list into
lex->save_order_list in order this head to be restored in
st_select_lex::add_window_spec after the specification of the
window function has been parsed.
Without a call of prepare_add_window_spec() when add_window_spec()
was called the head of an empty list was copied into
thd->lex->order_list (instead of assumed saved head this list).
This made the list thd->lex->order_list invalid and potentially
could cause many different problems.
Corrected the result set in the test case for MDEV-15899 that
used the MEDIAN window function and could not be correct
without this fix.
