when writing data to eeprom, source buffer should be const.
SRAM optimization - 176 bytes.

Moved expandedKey static buffer to the stack, and added as a parameter to those functions that use it.

I've not tested it, since I'm not using the smart config, but this looks like a safe change.

memory optimization: moved static expandedKey buffer to the stack. Saves 176 bytes of RAM.
hacking around with spi bus arbitration.  doesn't get past white LED - may be because of debug statements?

Git bisect led me to 6509c8367f as the offending commit.

The "CC3000 SpiWrite acquire bus" message and
the "CC3000 DmaHandler release read spi bus" message
do not break debug mode, but they create enough debug loggin
as to overwhelm the serial bus.

The "CC3000 DmaHandler release write spi bus" actually breaks
debug mode. Removed as unimportant.
