55ecebbe93 Implement rpmatch(), a semi-standard interface (as found on AIX, Tru64,
GNU) for determining whether a string is an affirmative or negative
response to a question according to the current locale. This is done
by matching the response against nl_langinfo(3) items YESEXPR and NOEXPR.

89b1ef2eaa Change the definition of NULL on ia64 (for LP64 compilations) from
an int constant to a long constant. This change improves consistency
in the following two ways:
1. The first 8 arguments are always passed in registers on ia64, which
   by virtue of the generated code implicitly widens ints to longs and
   allows the use of an 32-bit integral type for 64-bit arguments.
   Subsequent arguments are passed onto the memory stack, which does
   not exhibit the same behaviour and consequently do not allow this.
   In practice this means that variadic functions taking pointers
   and given NULL (without cast) work as long as the NULL is passed
   in one of the first 8 arguments. A SIGSEGV is more likely the
   result if such would be done for stack-based arguments. This is
   due to the fact that the upper 4 bytes remain undefined.
2. All 64-bit platforms that FreeBSD supports, with the obvious
   exception of ia64, allow 32-bit integral types (specifically NULL)
   when 64-bit pointers are expected in variadic functions by way of
   how the compiler generates code. As such, code that works correctly
   (whether rightfully so or not) on any platform other than ia64, may
   fail on ia64.

To more easily allow tweaking of the definition of NULL, this commit
removes the 12 definitions in the various headers and puts it in a
new header that can be included whenever NULL is to be made visible.

This commit fixes GNOME, emacs, xemacs and a whole bunch of ports
that I don't particularly care about at this time...

ea9527097a Don't blindly provide alloca() for all compilers -- it is too implementation
dependent.  Instead provide one for GCC & Intel's GCC copy and one for lint.
Anyone using any other translator tool needs to look closely at how that tool
can handle alloca.

d02cfc3692 Replace our ancient dtoa/strtod implementation with the gdtoa
package, a more recent, generalized set of routines.  Among the
changes:
- Declare strtof() and strtold() in stdlib.h.
- Add glue to libc to support these routines for all kinds
  of ``long double''.
- Update printf() to reflect the fact that dtoa works slightly
  differently now.

As soon as I see that nothing has blown up, I will kill
src/lib/libc/stdlib/strtod.c.  Soon printf() will be able
to use the new routines to output long doubles without loss
of precision, but numerous bugs in the existing code must
be addressed first.

o <machine/ansi.h> will continue to live so it can define MD clock
  macros, which are only MD because of gratuitous differences between
  architectures.
o Change all headers to make use of this.  This mainly involves
  changing:

cc3f58540b Fixed namespace pollution and/or breakage of K&R and C90 support related to
the following functions in the following commits:
- atoll() in revs 1.23-1.25
- llabs() and lldiv() in revs 1.22
- strtoq() and strtouq() in revs 1.18
C99 functions must not be declared in C90/POSIX.1-1990 sections, and
"long long" must not be exposed to compilers that don't support it.

Fixed style bugs (mainly misindentation and disorder) related the
following functions in the following commits:
- atoll() in revs 1.23-1.25
- getprogname() in rev.1.21
- sranddev() in revs 1.19-1.20
- strtoq() and strtouq() in rev.1.13
- user_from_uid() in rev.1.1
Breakage of K&R and C90 support used to be avoided by conditializing the
"long long"s for strtoq() and strtouq() on __STRICT_ANSI__, but the
conditionals should have gone away in rev.1.13 when the "long long"s went
away (the problem was moved to the places that declare quad_t and u_quad_t).

d54a12dd1f Add reallocf to the library. This function is simliar to realloc, but
when it returns NULL to indicate failure, it will also free the memory
that was passed to it, if that was non-null.

This does not change the semantics of realloc.

A second commit will be done to commit the conversion of those places in
the code that can safely use this to avoid memory leaks when confronted
with low memory situations.

655e9a55d2 Change the return types for strtoq and strtouq to int64_t and u_int64_t
instead of long long and unsigned long long. Really they should be
quad_t and u_quad_t, but that would require sys/types.h and this
header only includes machine/types.h. The difference here is that
int64_t and u_int64_t on alpha are long and unsigned long, not
long long etc. This is required to pass gcc's type checking where
long != long long even though they are the same size of alpha.
