Until now the native hardware was pulling PB5-7 down and checking if
they were asserted high. BMPMV2b is pulling the pins down instead of
high. The hardware version routine now determines the hardware version
based on the fact if a pin is asserted at all. This means that if a pin
is left floating, the version number bit will be 0, and if the pin is
asserted either high or low the bit will be set to 1. While we were
already at it the "monitor version" command in GDB will now also print
the hardware version number.
All source files include general.h first and before anything else.
This inlcludes platform.h and platform_support.h
No header file needs to include to include any of these, but should include
any others needed for it's own declarations.
