Use LONG_LONG_MAX and friends if available.
If we don't have LLONG_{MIN,MAX} but do have LONG_LONG_{MIN,MAX}
then use those instead. We do calculate these values in configure,
but it turns out that at least one compiler (old HP ANSI C) can't
parse "-9223372036854775808LL" without mangling it. (It can parse
"-9223372036854775807LL" which is presumably why its limits.h defines
LONG_LONG_MIN as the latter minus 1.)
Fixes rekey test when compiled with the aforementioned compiler.
