System clock is sort of working.

It appears the frequency divider does not work. I've followed the data
sheet, but no matter what I set the frequency divider to it appears to
not work. It's possible maybe the GPIO is using an un-divided clock, but
I'm not sure.

Also the 32khz clock does not work I think. It might be an issue with
the board. The waveform is jagged and looks awful.

But I can switch from the HSE to the PLL.

Fix exception handlers not being included during linking.

Get a good, basic framework for ISRs and properly handle the data sections.

Added a whole bunch of fiddle files. Started improving boot process.
