Reorganize directory structure
Moving to directory per-application layout. This facilitates building single applications which is useful in the Yocto build environment since different applications satisfy different OpenBMC build requirements. A number of issues are also addressed: - All applications were pulling in libsystemd and the gdbus libs irrespective of whether or not they were needed. - gpio.o duplicated in every application - moved to libopenbmc_intf - Added install target Signed-off-by: Brad Bishop <bradleyb@fuzziesquirrel.com>
