pca006132 0ce45b145e kernel: proper type for static shared variables. 
* Changed the KERNEL_CHANNEL_* to Mutex<T> with proper type, remove the
  need for unsafe.
* Exposed a const pointer to KernelImage, with UnsafeCell holding
  the library field for unbind with interior mutability.

pca006132 0310421085 RTIO DMA: Compiled but not working. 
* Cache flush should be done before playback instead when getting the
  handler.
* `csr::rtio_dma::enable_read()` would loop forever, probably bug in the
  gateware.

pca006132 4457af7277 rpc: Fixed alignment problem. 
Fixes issue #42.

Previously there was no fix for the variable alignment.
We calculate the position of the variable based on the size
of the previous variable, so we could break the alignment requirement
for variables. For example, having a `i64` after `bool` could break
the alignment required for `i64` and trigger DataAbort or data
corruption.

However, this requires the same data layout and LLVM type for the
variables. If this cannot be maintained, this would break the alignment
on the other side of the RPC, either from host to kernel or kernel to
host.
