avoid linker warning for compat symbols that are used internally in libc,
by introducing a hidden compat_foo() function, using that internally in
libc, and exposing foo as a strong alias to compat_foo(). I am open for
better ideas.

Make these work with _FORTIFY_SOURCE, by overriding the fortified definitions

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

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

#include "local.h" to get __flockfile_internal() prototype.

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 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

Need to wrap stdio stream locking around the function body. On the bright
side, getchar_unlocked() can now be used instead of getchar().

remove obsolete register declarations
