Introduce t_malloc_fail_after: if non-zero, it serves as a countdown to
...
setting t_malloc_fail. Also, enforce t_malloc_fail in realloc(), but not
before checking that the argument was valid.

Move the decision of whether to check for memory leaks from the malloc()
...
code to the driver and allow an environment variable to override the
default (on unless coverage is enabled).

If the test case changes desc, it *must* point to an allocated buffer
...
which the driver will free after printing the result.

Consistently use #if HAVE_FOO instead of #ifdef HAVE_FOO. The reason is
...
that AC_CHECK_DECLS([foo]), unlike AC_CHECK_FUNCS([foo]), will always
define HAVE_FOO, so #ifdef HAVE_FOO will always be true even if it is 0.
This commit finally fixes the [bl]e{32,64}{enc,dec} issue on Linux.

Create an additional test case which always runs after cleanup and checks
...
for memory leaks. It may be necessary to make this optional at some point,
but for now, none of our tests leak memory.

Refactor the malloc() etc code to reduce code duplication.
...
Introduce a t_malloc_fatal flag that makes unintentional allocation
failures fatal. This reduces the need for error handling in tests.
Enable that flag in t_main(). Test programs that don't want it can
override it in t_prepare().

when testing error handling code.
