minor improvement to make sysinit_run a constructor, so don't need
to manually call it anymore...

This required updating the linker script for the l1 part to include
the linkerset section..

This refactors out a bunch of code to make better use of the
SYSINIT mechanism...

Completes the PKI side of things for doing mutual authentication...

Uses a python script to generate the USB descriptors, and basic
interface code for the STM USB HAL Layer..  This gets ride of a lot
of the glue code that was previously written, allowing the glue code
to be easily changed/update...

break out the memory debug function into it's own file...

Minor fixes to the rs485 framing code...  Finally found the bug where
aborting a receive would corrupt the RX state for some reason...

Add back RNG seeding, and make it generic...

This follows the same protocol as the lora code, so the same
server should just work.

This gets USB CDC printing working..

add some more missing files now that it includes the symbols..

convert to using stdio to line buffer usb output... This reduces
usb traffic like when doing hexdump...

The delay works, but could be a problem on slower systems...  It's
been reported, so hopefully a fix will happen..

Before this, I was VERY frequently having to retry..  changing just
the gw improved things significantly, but changing it on both results
is no observable retries..  This is also the default that the example
apps in loramac uses..

eliminate the strobe code as it isn't used, this just pushes
packets back and forth..

3-4 seconds to gather all this...  need to add a blinking light to this
so it's clear that it's still starting..

This is better than using RAM, as it keeps the state between power
cycles...

all working...
