normal dmesg (which has to use kvm) doesn't work.

step toward producing ELF core dumps in the proper format. I will
commit the code to generate the ELF core dumps Real Soon Now. In
the meantime, ELF executables won't dump core at all. That is
probably no less useful than dumping a.out-style core dumps as they
have done until now.

consolidates some code that was starting to be duplicated in more

it could. The compiler should limit itself to functions that are
widespread, to ease porting and cross-compilation.

source files. It's cleaner than it was before, but it's still
pretty crufty.

have to be rebuilt for it to work, including the compiler and all
of the profiled libraries.

Maintain a mapping from (iopaic number, int pin) tuple to irq number,

Previous code assumed that irq number was equal to int pin number, and

Normally the full 640x480 (768x576 PAL) image is grabbed. This ioctl
allows a smaller area from anywhere within the video image to be
grabbed, eg a 400x300 image from (50,10).
