It adds a shell script to read the data files therein and generate something useful for gdbserver; GDB can use the same or a different script. You could argue that the script and header contained in this patch belong in the gdbserver directory; I'll do whichever the first person who feels like approving this prefers :) I include data files for the current remote packets for MIPS, ARM, SH, i386, PowerPC, M68k, and ia64. Adding others is pretty easy. This is one of the big steps in cleaning up gdbserver. They're not quite right yet - I think that perhaps the sizes should be in bits rather than bytes. I can fix that up before commiting, though, and I can't think of any other issues. I'd like to commit this so that I can then re-arrange gdbserver to use them. OK?
