The current post_log_word in global data is currently split into 2x 16 bits: half for the test start, half for the test success. Since we alredy have more than 16 POST tests defined and more could be defined, this may result in an overflow and the post_output_backlog would not work for the tests defined further of these 16 positions. An additional field is added to global data so that we can now support up to 32 (depending of architecture) tests. The post_log_word is only used to record the start of the test and the new field post_log_res for the test success (or failure). The post_output_backlog is for this change also adapted.
