[test] Add okx() macro taking an explicit file name and line number
Allow test reports to specify an explicit file name and line number
using the extended okx() macro. This allows large blocks of test
report code such as tcpip_random_ok() to be implemented as functions
rather than macros.

[test] Add a basic infrastructure for running self-tests
This self-test mechanism is inspired by Perl's Test::Simple and
similar modules. The aim is to encourage the use of self-tests by
making it as easy as possible to create self-test code
