I don't like magic variables that much, but we have them and they are at
times very convenient to use. The problem with those variables is that
we don't know which variables exist in a running binary, so this patchset
adds a 'magicvar' command which prints information about the magic variables.
The description for magic variables can be put next to their user and
the description completely compiles away when the magicvar command is not
selected.
