Subject: scripts/decode_stacktrace.sh: add '-h' flag
Date: Fri, 23 Aug 2024 10:27:44 +0200
When no parameters are passed, the usage instructions are presented only
when debuginfod-find is not found. This makes sense because with
debuginfod none of the positional parameters are needed. However it means
that users having debuginfod-find installed will have no chance of reading
the usage text without opening the file.
Many programs have a '-h' flag to get the usage, so add such a flag.
Invoking 'scripts/decode_stacktrace.sh -h' will now show the usage text
and exit.
