compare-sections: New -r option.
When connecting to a remote system, we use the compare-sections
command to verify that the box is running the code that we think it is
running. Since the system is up and running and *NOT* 'freshly
downloaded without yet executing anything', read-write sections, of
course, differ from what they were in the executable file.
Comparing read-write sections takes time and more importantly the
MIS-MATCHED output is confusing to some users.
The compare-sections command compares all loadable sections including
read-write sections. This patch gives the user the option to compare
just the loadable read-only sections.

all loadable read-only sections.

option.
