debugcommands: add support for extensions adding their own debug info

We've had a couple of cases where it'd be handy at Google to add data
to `hg debuginstall`'s output. We've kludged around that at various
times, but it seems reasonable to let extensions add their own data
here so extension maintainers can get useful extra data.

# Disable the $CAP wire protocol capability.

if test -z "$CAP"
then
    echo "CAP environment variable not set."
