Richard Levitte 208d721a00 TAPify testutil
With the perl test framework comes the output format TAP
(Test Anything Protocol, see http://testanything.org/) with
extra extension for subtests.  This change extends that same
output format to any test program using testutil.

In this implementation, each test program is seen as a full test that
can be used as a subtest.  The perl framework passes on the subtest
level to the test programs with the environment variable
HARNESS_OSSL_LEVEL.  Furthermore, and series of tests added with
ADD_ALL_TESTS is regarded as another subtest level.

/* The size of memory buffers to display on failure */

/*
* A common routine to output test failure messages. Generally this should not
* be called directly, rather it should be called by the following functions.
*
* |desc| is a printf formatted description with arguments |args| that is
* supplied by the user and |desc| can be NULL. |type| is the data type
* that was tested (int, char, ptr, ...). |fmt| is a system provided
* printf format with following arguments that spell out the failure
* details i.e. the actual values compared and the operator used.
*
* The typical use for this is from an utility test function:
*
* int test6(const char *file, int line, int n) {
* if (n != 6) {
* test_fail_message(1, file, line, "int", "value %d is not %d", n, 6);
* return 0;
* }
* return 1;
* }
*
* calling test6(3, "oops") will return 0 and produce out along the lines of:
* FAIL oops: (int) value 3 is not 6\n
*
* It general, test_fail_message should not be called directly.
