Increase YPMAXRECORD to 16M to be compatible with Linux.
Since YP protocol definition uses the constant to declare
variable-size opaque byte strings, the change should be binary
compatible with existing installations which do not expose keys or
values larger than 1024 bytes.
All uses of local variables with YPMAXRECORD sizes were removed to
avoid insane stack use. On the other hand, variables with static
lifetime should be fine and only result in increased VA use.
Glibc made same change, increasing the allowed length for keys and
values in YP to 16M, in 2013.
