Bug #351570: Hidden function fixes: rc_conf_value.

Refactor rc_conf_value into librc for use in library context.
Also requires moving:
- rc_conf internal static
- Defines: PROFILE_ENV, SYS_WHITELIST, USR_WHITELIST, RC_PATH_PREFIX
  moved to rc.h with new RC_ prefix added.
- Defines: RC_CONF, RC_CONF_OLD moved to rc.h.
