Remove more bogus tests for 64-bit i386 and SuperH.

These are always false.

Use C89 Prototypes.
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)

struct netnet.n_net used to be an unsigned long integer.

In XNS5, and subsequently in POSIX-2001 it was changed to socklen_t.

To accomodate for this while preserving binary compatibility with the
old interface, prepend or append 32 bits of padding, depending on
the (LP64 data model) architecture's endianness. Fixes PR
standards/21411 from Ben Harris.

This should be deleted the next time the libc major number is
incremented.

Also, update getnetbyaddr(3)'s `net' argument accordingly.

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

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

sync with BIND 4.9.7. mostly costmetic.

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

$Id: -> Id: (to make hunting down other bad Ids easier).

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>.

merge bind 4.9.6 resolver. still need to fix <resolv.h>

Fix RCSID's
Fix gcc warnings
Add missing prototypes
Use "namespace.h"

merge in the bind 4.9.5-P1 resolver. we are now _mostly_ the
same as this, with our changes also included (resolv.conf and
other minor differences).

merge with the resolver in bind 4.9.3-P1.

Don't read the network address as an alias when there isn't whitespace
after the network address. Closes PR 1940.

clean up import. also convert everything to new Id format.

Declare rcsid strings so they are stored in text segment.

Add RCS identifiers.
