test: Make TEST_* report test location

This patch converts TEST_* functions to macros, which print file name
and line # of the check. This will allow us to locate a failed test

New TEST_* macros also automatically generate a test name if
testname == NULL. This will save us time to think of a name for
every single check we write in a test.
