convert explicit length check before unchecked snprintf() with just a
overflow checked snprintf(). for res_debug.c and res_query.c, convert
from sprintf() to snprintf().

tested scp and rcp fail properly with too-long paths.
tested getaddrinfo fails as expected for too-long domains.
tested dig and ping for similar (res_debug.c/res_query.c).
created a temporary fs with quotas to test edquota with a long EDITOR.
did not test ypserv directly, but it's the same pattern.

avoids GCC 12 snprintf() warnings, and reduces total code size.

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)
