Issue 187 enable skipped ztest suites (#189)

* Fix some ztests that were skipped * Expose bacapp_same_value() * Fix bacapp, ptransfer tests * Fix bugs in Load_Control object & tests * refactor days functions from datetime module * fix legacy ctests * Add bacnet/basic/sys/days.[ch] to Zephyr build * Update ztest to match from Zephyr v2.6.0; update ringbuf, datetime to build * Fixup ztest test for object/acc * Fix bvlc_address_from_ascii; enable/fix bvlc test * Comment cleanup * test/bacnet/basic/object/lc partially enabled * Fix bacapp_decode_data_len return status on erroneous input * fix ztest include fatal error * fix ztest strsignal reference fatal error * fix zassert_mem_equal reference syntax error * fix zassert_mem_equal reference syntax error Co-authored-by: Gregory Shue <gregory.shue@legrand.us> Co-authored-by: Steve Karg <skarg@users.sourceforge.net>
