Don't pollute the namespace with stdint.h. (This file is included from string.h so it can't blithely do whatever it feels like.) PR 45258.

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.

Move <null.h> to <sys/null.h> for the purpose of avoiding conflicts due to std C headers including it, and a kernel module written in C++ would benfit as well.

Add popcount(3) and the long and long long version. Name is inspired by gnulib, the implementation goes back to the AMD Software Optimizer guide. A number of platforms will want to replace the C version with assembler code using native instructions.

#if _FORTIFY_SOURCE > 0
Match usage of FORTIFY_SOURCE on other platforms by not requiring special include path: the normal header files now include the "SSP" ones (which one should note are not really named right: SSP and FORTIFY_SOURCE are independent features). Disable USE_SSP on targets where the compiler doesn't support it at all (mips, alpha) or it's known broken (sh3). But enable FORTIFY_SOURCE, without SSP, on those platforms -- tested on mipsel.
