This patch moves more includes (most of them, to tell the truth) to common/include directory. This completes the list of includes needed to compile current trunk with the new libc (but to do that you need more patches in queue). This patch also contains some modification (for compilation with new headers) to the common includes under __NBSD_LIBC, the define used in mk script to specialize compilation with new includes.
