while changing things, add a crypt_checkpass wrapper that handles most of
the edge cases. (not quite ready for production, though.)

The sparcv9 BN code is not enabled, as it expects to run on a 32-bit

Note that GCM128 Neon code is currently not built (and thus not tested), as
the current toolchain does not support Neon instructions.

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.
