Peter Weingartner 31258d63d3 Fixed file execution from flash 
The kernel was unable to start a user mode program when the kernel was in flash. I have changed how the call_user assembly code starts the user mode program to fix this.

Peter Weingartner b315be98b7 Channel Redirection 
Added basic support for redirecting channel IDs to other channels (sys_chan_swap and sys_chan_dev).

Current flash version is not quite working... panics on running an external file.

Peter Weingartner 51b65de7bd LPT Channel Support 
A rough LPT driver is now working with channels. Only seems to work on an Epson printer, and that somewhat inconsistently. Needs to be more robust and to respond to error conditions from the printer.

Peter Weingartner c9c5bb9314 Made flashable 
Updates to get a version of the kernel that can be stored in flash. The data segment is in the first 64KB and may need to be moved. Also, there is some glitching with the line editing routines.
