This patch (against EWB's boot segment patch) fixes the abuse of 
empty_zero_page for storing boot parameters.  This usage is an artifact 
from before we had discardable init sections.

- Move some constants to setup.h
- Copy the command line directly to saved_command_line
- Add boot_params as temporary storage of the parameters block
- Move empty_zero_page to .bss
