include: * Rework the way that poll() is detected so that it more closely follows how the rest of the replacement functions are detected. * Split err*() and warn*() functions into separate err.c and warn.c files so that we can more finely isolate the objects files pulled in by the linker. This should fix building textproc/nbsed on Solaris. * Move more definitions from nbcompat.h into nbcompat/*.h. This makes it more clear which NetBSD headers are expected to provide which function declarations and macro definitions. * Clean out nbconfig.h by moving all of the relevant definitions into the correct nbcompat/*.h files. * Update all of the library functions to the latest from src HEAD. Also change the way that sources are modified when imported -- we now include <nbcompat.h> before the first system header, include <nbcompat/*.h> versions of headers instead of system ones where available, and "#if 0" the sections that make no sense when being built outside of the NetBSD source tree. This should make future updates from src HEAD, e.g. for security updates or bug fixes, easier. * Move all private headers into a subdirectory and include the headers from the private directory. This avoids any nameclashes with system headers with the same name.
