renaming config.h in oc_app_config.h

[peters-r]

Hi,

i think it would be better to rename config.h to oc_app_config.h or something like that, since this file is a dependency in a lot of source files which may clash with application config files that are not related to IoTivity.

This is an issue, because (e.g. for Zephyr) the port/ folder is actually part of the application code in terms of the build system.

Regards, Richard

@peters-r Thanks for the suggestion. I'll look into doing that.
