This patch simplifies the system call bindings. The common syscall bindings in 'src/platform/' have been reduced to the syscalls needed by non-core programs. The additional syscalls that are needed solely by core have been moved to 'src/core/include/core_linux_syscalls.h'. Furthermore, the resource path is not used outside of core anymore. Hence, we could get rid of the rpath library. The resource-path code has been moved to 'src/core/include/resource_path.h'. The IPC-related parts of 'src/platform' have been moved to the IPC library. So there is now a clean separation between low-level syscall bindings (in 'src/platform') and higher-level code. The code for the socket-descriptor registry is now located in the 'src/base/ipc/socket_descriptor_registry.h' header. The interface is separated from 'ipc.cc' because core needs to access the registry from outside the ipc library.
