(Mostly) automatic merge
Fixed also some failing tests after merge. The files that was touched outside of the merge has a more explicit comment
include/my_global.h:
Remove 'register' from 'swap_variables' as this gives a warnings when the variables are structs. Compilers should also now be smart enough to figure out this themselves
mysql-test/t/subselect_debug.test:
Reset value of the debug variable; Without setting this the subselect_innodb test will fail when run after this one
sql/mysqld.cc:
Fix for Bug #39987 main.partition_not_windows fails under debug build
The problem was that when compiling for purify/valgrind realpath() is not used, which causes test_if_data_home_dir to fail when it shouldn't
unittest/mysys/waiting_threads-t.c:
Remove not needed 'volatile' to get rid of compiler warnings on windows
