remove diag assert - the compiler demands fp is non NULL now.

fixes for GCC 6:

- -Wstrict-prototypes is not available for C++, so don't try to
ignore it for C++.
- remove many _DIAGASSERT() checks against not NULL for functions
with arguments with nonnull

fixes for GCC 6:

- -Wstrict-prototypes is not available for C++, so don't try to
ignore it for C++.
- remove many _DIAGASSERT() checks against not NULL for functions
with arguments with nonnull attributes. in two cases, leave
code behind that should set defaults to "(null)".
- use -Wno-error=frame-address for i386 mcount, as it seems valid
to assume the caller will have a frame.fair

Add explicit locale versions for the printf family. Replace asprintf,
snprintf and sprintf with simple wrappers around the corresponding
va_list functions to reduce code duplication.

- no functional changes

Move UCB-licensed code from 4-clause to 3-clause licence.

Patches provided by Joel Baker in PR 22280, verified by myself.

Merge the nathanw_sa branch.

__STDC__ is always defined on NetBSD.

back out the #ifdef _DIAGNOSTIC argument checks; too many people complained.
_DIAGASSERT() is still retained.

* use _DIAGASSERT() to check pointer arguments against NULL and file
descriptors against -1 (as appropriate).

* use _DIAGASSERT() to check pointer arguments against NULL and file
descriptors against -1 (as appropriate).
* add actual checks which to detect stuff that would trigger_DIAGASSERT(),
and attempt to return a sane error condition.
* knf some code
* remove some `register' decls.

the first two items result in the addition of code similar to the
following in various functions:

_DIAGASSERT(path != NULL)
#ifdef _DIAGNOSTIC
if (path == NULL) {
errno = EFAULT;
return (-1);
}
#endif

Fix RCSID's
Fix gcc warnings.
Add prototypes for functions that were declared in more than one place
to local.h or extern.h and use that instead.

Merged with 4.4lite.
Changed to conform to NetBSD's new RCS Id convention.

Add explicit return types to function definitions.

Declare rcsid strings so they are stored in text segment.

Add RCS identifiers.
