Add a new feature-test macro, _NETBSD_SOURCE. If this is defined by the application, all NetBSD interfaces are made visible, even if some other feature-test macro (like _POSIX_C_SOURCE) is defined. <sys/featuretest.h> defined _NETBSD_SOURCE if none of _ANSI_SOURCE, _POSIX_C_SOURCE and _XOPEN_SOURCE is defined, so as to preserve existing behaviour. This has two major advantages: + Programs that require non-POSIX facilities but define _POSIX_C_SOURCE can trivially be overruled by putting -D_NETBSD_SOURCE in their CFLAGS. + It makes most of the #ifs simpler, in that they're all now ORs of the various macros, rather than having checks for (!defined(_ANSI_SOURCE) || !defined(_POSIX_C_SOURCE) || !defined(_XOPEN_SOURCE)) all over the place. I've tried not to change the semantics of the headers in any case where _NETBSD_SOURCE wasn't defined, but there were some places where the current semantics were clearly mad, and retaining them was harder than correcting them. In particular, I've mostly normalised things so that _ANSI_SOURCE gets you the smallest set of stuff, then _POSIX_C_SOURCE, _XOPEN_SOURCE and _NETBSD_SOURCE in that order. Tested by building for vax, encouraged by thorpej, and uncontested in tech-userlevel for a week.

__END_DECLS
Remove the (int) cast from the array subscript of the ctype #defines. The cast just stops gcc detecting places where the functions are passed a 'char' variable - and will index off the array for byte values 0x80 to 0xff. All (I hope) of the places in the netbsd sources where this was a potential problem have had an (unsigned char) cast applied. Christos said he'll fix any fallout I've missed.
