Added small tool source_to_data, which takes an arbitrary data file and

generates a C source file defining an array variable containing the file's
data. DataFileToSourceFile is the respective jam rule.

The idea is to directly built the boot archive into the boot loader for
network booting (and thus avoiding to download it from somewhere). In
case of PXE this doesn't work, though, due to restrictions to the size
of the NBP. Maybe Open Firmware is less restrictive.
