The C{run()} method returns os.WEXITSTATUS(res) without checking
os.WIFEXITED(res) first, so it can signal that everything is ok,
even though something causes dpkg not to exit cleanly.
Save whether dpkg exited cleanly into the C{dpkg_exited}
attribute. If dpkg exited cleanly the exit code can be used to
determine whether there were any errors. If dpkg didn't exit
cleanly it should mean that something went wrong.

When dpkg reports an error, a SystemError is raised and cleaned
up in C code. However, it seems like the Apport except hook is
called before the C code clears the error, generating crash
reports even though nothing crashed.
This exception hook doesn't call the Apport hook for
SystemErrors, but it calls it for all other errors.

It's considered broken if it's one that we marked for install,
but it's not marked for install, upgrade or downgrade
anymore.
Before Trusty, checking is_inst_broken was enough, but
in Trusty the behaviour changed, so the package simply gets
unmarked for installation.
