switch to generating them by default. prodded by deraadt and sthen

2. Pull up the actual minor processing code into the switch that
parses it.
3. atoi is actually simpler than strtonum in this case, but check the
input beforehand so we don't get unexpected results.
4. Slightly more consistent style between various parse and check and
increment operations on salt.

This is a getaddrinfo() flag that is defined thusly in RFC 3493:
If the AI_ADDRCONFIG flag is specified, IPv4 addresses shall be
returned only if an IPv4 address is configured on the local system,
and IPv6 addresses shall be returned only if an IPv6 address is
configured on the local system.  The loopback address is not
considered for this case as valid as a configured address.
For example, when using the DNS, a query for AAAA records should
occur only if the node has at least one IPv6 address configured
(other than IPv6 loopback) and a query for A records should occur
only if the node has at least one IPv4 address configured (other
than the IPv4 loopback).
The flag is set by default when hints is NULL.

we always junk small chunks now, and the first part of pages,

Consider experimental as we evaluate performance in the real world.
