libc/gen: fix hack for previously unsupported lint initializers

Supported since init.c 1.182 from 2021-03-30.

Avoid complicated arithmetic involving NULL.

branches: 1.36.12;
simplify cast.

branches: 1.35.2;
add a couple of casts.

Get rid of all sysc_init_field uses - initialize fields directly in C99
notation.

When creating the descriptions for the "user" node, advance the output
pointer properly.

branches: 1.32.2; 1.32.8;
Use C89 definitions.
Remove use of __P

PR/45989: Martin Husemann: lint invocation does include -w only on i386

- turn lint -w for all the platforms after fixing the lint warnings.
- add _DIAGASSERTS() for casts that would assign values to types that
would not fit.
- change types, add casts
- change into ansii prototypes
- turn on _DIAGNOSTIC for libc (during current, to be eliminated for release
builds)

Replaced strncpy with strlcpy. Thanks to Peter Postma who
pointed them our in PR #25762. Approved by christos@NetBSD.org.

Remove dynamic sysctl node version 0 from the tree. It seemed okay at
first, but quickly showed its shortcomings. The version 1 node we're
now using should be good for a while.

Avoid using preprocessing conditionals in a macro argument list at least
as long as all ports have not yet been converted to using gcc 3.3.3.

Build bug discovered when building for vax.

Descriptions for user.* sysctl nodes. Mostly copied from sysctl(3).

branches: 1.23.2;
Introduce sysc_init_field() and use it to make the code a little less ugly.
Also, fix another gcc2-unfriendly initialization.

Modify this so that it actually compiles with gcc2.

Unwind the nested designators for fields within structs within structs
(or unions). This should really be put back once we're all using gcc3
for everything, since that makes it look a *lot* cleaner.

Description framework for user-level sysctl nodes. Still haven't
written the descriptions.

New node version and layout. This should take care of the netbsd32
emulation problem, formalizes the versioning (should it ever be needed
again), and provides a slot for descriptions.

The new sysctl query interface returns the same information as the old
one, but you must pass in an empty node that indicates the version
you're using.

Remove my private hack for watching how sysctl works. That's not
supposed to be there.

Tango on sysctl_createv() and flags. The flags have all been renamed,
and sysctl_createv() now uses more arguments.

oops

Adapt userland sysctl goop to new world order, permitting dynamic
discovery.

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

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

Add a sysconf(3) knob for {ATEXIT_MAX}.

branches: 1.11.6;
Delint.
Remove trailing ; from uses of __weak_alias(). The macro inserts this if
needed.

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

Now that it's delinted, make it compile on LP64 platforms again. (Using a
size_t for namelen isn't strictly appropriate/necessary anyhow.)

delint

If port provides __weak_alias(), provide an Standard C and POSIX pure
identifier namespace by renaming non standard functions and variables
such that they have a leading underscore. The library will use those
names internally. Weak aliases are used to provide the original names
to the API.

This is only the first part of this change. It is most of the functions
which are implemented in C for all NetBSD ports. Subsequent changes are
to add the same support to the remaining C files, to assembly files, and
to the automagically generated assembly source used for system calls.
When all of the above is done, ports with weak alias support should add
a definition for __weak_alias to <sys/cdefs.h>.

Include "extern.h" to pick up prototype for sysctl.
