Subject: main.c: Allow scanning multiple processes by name
X-Git-Url: http://git.itanic.dy.fi/?p=scan-pagemap;a=commitdiff_plain;h=079a74b05e89f918b3a4348be6163f6ebe0b26b4

main.c: Allow scanning multiple processes by name

Now that we have code in place for scanning multiple pid numbers, we
can also convert all process names to pids. That way, it becomes also
possible to add all process names user has given as an argument.
