We were using dwfl_standard_argp but trying to add our own and
some options from it. dwfl_standard_argp also handles kernel, modules,
executables without state and process maps that stack doesn't support.
That made argp parsing somewhat ugly and meant our --help and --usage
didn't really match. Just handle the dwfl_standard_argp options we do
want directly ('-p', '--core', '-e' and
'--debuginfo-path'). That way
we can also do sanity checking on the options given.
I pushed this and the better error handling patch to master, including
some of the new arguments to stack (-l, -1, -r, -b and -n).
stack: Add new '-n MAXFRAMES' option. Resolve addresses after unwind.
stack: -b, --build-id shows module build-id, load address and pc offset.
stack: Simplify argument parsing. Don't use dwfl_standard_argp.
stack: Add --quiet to not resolve addresses, add --raw to not demangle.
stack: Improve error checking and exit code handling.
stack: Add -l, --list-modules. Show module memory map, build-id and files.
