#384 sysini GPF when using "all:"

[fpefpe]

There is a bug in the sysini call in regutil

The issue is with the win32 api call GetProfileSection* calls and the
way the return code was tested

I wrote this fix some time ago, and I think it still should
work, but I would test it in the regutil.rexx file

The bug is found in the regini.c file with the internal functions list_keys
and list_apps

This fix refactors both of those routines
