Add a way to make assertions non-fatal

Browse Source 
When using test harnesses other than gtester (e.g. using TAP),
it can be suboptimal to have the very first failed assertion
abort the test suite.

This commit adds a g_test_set_nonfatal_assertions() that can
be called in a test binary to change the behaviour of most
assert macros to just call g_test_fail() and continue. We
don't change the behavior of g_assert() and g_assert_not_reached(),
since these to assertion macros are older than GTest, are
widely used outside of testsuites, and will cause compiler
warnings if they loose their noreturn annotation.
