d0d687a239 utra: fix build on non-hardware release 
This adds svd2utra, which enables building for non-embedded harware.

It also fixes some build issues, and paves the way for generating UTRA
at compile-time.

ea3a473c9f reworking memory allocation 
The kernel should run in a `no_std` environment, which means it must
currently run without `alloc`. We have our own allocation methods when
running on baremetal hardware.

Begin the work to break out the allocation method so that it will work
on both desktop and baremetal environments.

21aa67b748 workspace: remove workspace 
The kernel and userspace both need to use `xous`, but have different
requirements. If we use a workspace, then all instances of `xous-rs`
must have the same feature set.

This breaks them apart so the kernel can have one set of features and
programs can have another set.

As part of this change, tests are now integrated into the kernel, and a
new `create_process_as_thread()` and `wait_process_as_thread()` function
pair have been added.

723529ba20 wip: working on getting message passing working 
The goal is to get a basic message passing engine working that will also
function as a device that works on real hardware.

This is still reworking it to function correctly on a desktop system.
Once that is working, it will be reworked to function once again on
hardware.
