Add a function attribute called `__malloc_like', which informs gcc
that the annotated function returns a pointer that doesn't alias any
extant pointer. This results in a 50%+ speedup in microbenchmarks such
as the following:

char *cp = malloc(1), *buf = malloc(BUF);
for (i = 0; i < BUF; i++) buf[i] = *cp;

In real programs, your mileage will vary. Note that gcc already
performs this optimization automatically for any function called
`malloc', `calloc', `strdup', or `strndup' unless -fno-builtins is
used.

Add fgetwln(), a wide character version of fgetln().

Fix typo in putwc().

Noticed by: stefanf

Bring back the macro versions of getwc(), getwchar(), putwc() and
putwchar(), but this time avoid redundantly declaring __stdinp and
__stdoutp when source files include both <stdio.h> and <wchar.h>.

Revert to rev. 1.36 until issues with -Wredundant-decls are sorted out.

Fix typo in previous: getwc() should call fgetwc(), not the function
version of itself.

Noticed by: stefanf

Provide trivial macro implementations of getwc(), getwchar(), putwc() and
putwchar() to reduce function call overhead.

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...

Restrict qualifiers were added to the existing prototypes in <inttypes.h>
and the typedef for wchar_t was removed.

formatted wide-character output.

Restrict visibility of wcslcat() and wcslcpy() to the __BSD_VISIBLE case.

Add wcstod() as a wrapper around strtod(). It does not handle any characters
that strtod() does not (alternate digit characters, etc. are not handled).

Style: tab between #define and macro name.

Protect arguments to the putwc and putwchar macros with parens.
