this cleans up some namespace issues when including
the utra crate which also refers to utra::generated::utra,
and there are CONST at the crate-level, and also functions
at the module-level which need disambiguation. By naming
the crate utra-lib this saves a bit of syntatic wrangling
at the top of every file.
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.

The log, graphics, and shell processes now all talk to one another. This
illustrates how multiple processes can communicate regardless of what is
going on underneath.

Previously, the `baremetal.rs` library was removed. This resulted in
this program no longer running on hardware.
Add this library back in.

These packages modify RUSTFLAGS, which causes some packages to be
rebuilt every time. Move them out of the workspace so as to ensure they
don't use the same `target` directory.

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.

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.

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.

This lays groundwork to support lending pages from one process to
another, and to restore permissions when pages are handed back.
