Command line arguments

[Ed Sutter]

Lars,
I beleive this is boot loader specific.  At the time of command
line entry, the boot loader is still the active program, so it 
must provide the ability to deal with arguments.  In MicroMonitor,
this is very easy to do and pretty much independent of the CPU/RTOS.

Command line arguments established when the application starts up
are stored in the monitor's environment, then through a monitor
API call, they can be retrieved from anywhere in application
space (assuming the application doesn't disallow access to the
monitor's API because of MMU-based protection).

In most uMon-based applications, this API call is made prior to main()
so that argc/argv are populated just like a normal program; however,
this isn't a requirement.
