This is a change to VAX adb which makes it print the saved registers in each
stack frame when the 'C' option is used. This is what the RT adb does; I
find it a very useful feature.
I decided to write my addition in C instead of the strange language the rest
of adb is written in, so it doesn't look much like the surrounding code.
