stack: show binary and source file names where a function is defined

stack: show binary and source file names where a function is defined

This patch adds the module and source file information to the
each stack trace line.  `-m' is for module file information
and `-s' is for source file information. `-v' is for both and more.

This is based on private discussion with Jan Kratochvil
<jan.kratochvil@redhat.com>.

In v2 patch, `-s' and `-m' options are introduced instead
of using `-v' repeatedly as suggested by Mark Wielaard <mjw@redhat.com>.

In v3 patch `-a' is added as extra option and source lines are
printed on their own line.
