The moving of kernel-only code out of kutil continues. (See 042f061)
This commit moves the following:
- The heap allocator code
- memory.cpp/h which means:
- letting string.h be the right header for memset and memcpy, still
including an implementation of it for the kernel though, since
we're not linking libc to the kernel
- Changing calls to kalloc/kfree to new/delete in kutil containers
that aren't going to be merged into the kernel
- Fixing a problem with stdalign.h from libc, which was causing issues
for type_traits.
This change adds a new interface DSL for specifying objects (with
methods) and interfaces (that expose objects, and optionally have their
own methods).
Significant changes:
- Add the new scripts/definitions Python module to parse the DSL
- Add the new definitions directory containing DSL definition files
- Use cog to generate syscall-related code in kernel and libj6
- Unify ordering of pointer + length pairs in interfaces
