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

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

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).
* add actual checks which to detect stuff that would trigger_DIAGASSERT(),
and attemp

* 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

Minor KNF nit.

Partly backing out last change, only leaving lstat() instead of stat().
Pointed out by Enami Tsugutomo <enami@but-b.or.jp>.

remove(3) doesn't remove dangling links due to stat() returning an
error. Now try lstat() before really aborting.
OK'd by thorpej.

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.

Always use rmdir(2) to remove a directory, as the file system may prohibit
using unlink(2) on directories.

Add explict function return types

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

Declare rcsid strings so they are stored in text segment.

Add RCS identifiers.
