show dialog count without rotation when using --no-interface

When using --no-interface without --quiet, a dialog counter
is shown and continously updated. Without this patch this
counter just shows the number of calls that are stored in RAM.
When rotation is used, it never shows more calls than the
rotation limit.

Since the --no-interface option is usually just used for
capturing, using it with a small number for rotation (down to 1)
is recommended to not waste RAM. This means the shown value
is useless.

This patch introduces the function sip_calls_count_unrotated() that
can be used to get the full number of calls since program start.
This is then used in the shown dialog count.
