/**
* Variant of `malloc` that conditionally clears the allocation with zeroes.
*
+ * `mallocz(size, clear)` is equivalent to
+ * both `(clear ? zalloc : malloc)(size)`
+ * and `(clear ? calloc(1, size) : malloc(size))`.
+ *
* This is a Plan 9 from Bell Labs extension.
*
* @param size The size of the allocation.
