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)

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

Back out part of the last change. This broke on the alpha (or wherever
sizeof(u_int32_t) != sizeof(*)), at least in cases with re->re_g->nstates
between 32 and 64.
Primary reason for the breakage was that the "states1" definition didn't
work as expected. (It didn't work before either, but this was not noticed
due to sizeof(long)==sizeof(*).)
The alpha can handle larger problems with the "small" state machine model
if a "long" is used as state variable, so it is better to keep the old
definition here. (u_int32_t is left for the "operator" variables.)
Use "int" as "sopno" - this is used as index into the states field, there
is no point in using a fized-size type.

Delint:
- we don't need to use longs; convert to use int32_t.
- remove break statements after returns.
- cast things properly.

remove obsolete register declarations

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>.

Don't cast 'INC()'s argument's type, since it's an lvalue and cast
