/** Allocate memory dynamically and fail the test case if this fails.
* The allocated memory will be filled with zeros.
*
* You must set \p pointer to \c NULL before calling this macro and
* put `mbedtls_free(pointer)` in the test's cleanup code.
*
* If \p item_count is zero, the resulting \p pointer will not be \c NULL.
*
* This macro expands to an instruction, not an expression.
* It may jump to the \c exit label.
*
* \param pointer An lvalue where the address of the allocated buffer
* will be stored.
* This expression may be evaluated multiple times.
* \param item_count Number of elements to allocate.
* This expression may be evaluated multiple times.
