PR/50367: Stefan Schaeckeler: Apply fix to obey RES_CHECKNAME to getnetbyaddr
and getnetbyname.

branches: 1.42.10; 1.42.12;
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)

fix incomplete initializers

Change type of `net' variable passed via va_list in
_{files,dns,yp}_getenetbyaddr() functions from unsigned long to uint32_t.
In rev 1.29, getnetbyaddr(3) was changed to take uint32_t `net' argument
and also passisng uint32_t `net' to nsdispatch(3) varargs, but
these callback functions were not changed accordingly.

Patch was provided by christos, and this fixes amd(8) coredumps on alpha

centralize res_*init() calls in __res_get_state()

Finish bind9 resolver merge.

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.

fix remote buffer overrun. from openbsd tree (1997).

allocate 64K recieve buffer for DNS responses.

eliminate sprintf, use snprintf. check strlcat error.

avoid remote buffer overrun on hostbuf[]. From: Joost Pol <joost@pine.nl>

correct bad practice in the code - it uses two changing variables
to manage buffer (buf and buflen). we eliminate buflen and use
fixed point (ep) as the ending pointer.

this fix is critical.

back out the #ifdef _DIAGNOSTIC argument checks; too many people complained.

* 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

errno = EFAULT;
