In cltsetup(), when checking the address, use clp's naddr for index,
instead of cltarg's naddr, which it's always zero there.

Introduce DNS query helpers based on getaddrinfo(3) and
getnameinfo(3). These will eventually replace the existing
hostent-based functions in support/export/hostname.c.
Put some of these new helpers to immediate use, where convenient.
As they are part of libexport.a, I've added the forward declarations
for these new functions in exportfs.h rather than misc.h, where the
hostent-based forward declarations are currently.

To store non-AF_INET addresses in the nfs_client structure, we need to
use more than in_addr for the m_addrlist field. Make m_addrlist
larger, then add a few helper functions to handle type casting and
array indexing cleanly.
We could treat the nfs_client address list as if all the addresses
in the list were the same family. This might work for MCL_SUBNETWORK
type nfs_clients. However, during the transition to IPv6, most hosts
will have at least one IPv4 and one IPv6 address. For MCL_FQDN, I
think we need to have the ability to store addresses from both
families in one nfs_client.
Additionally, IPv6 scope IDs are not part of struct sin6_addr. To
support link-local IPv6 addresses and the like, a scope ID must be
stored.
Thus, each slot in the address list needs to be capable of storing an
entire socket address, and not simply the network address part.

Contrary to the comment above its definition, the field m_path always
has the same value as e_path: the *only* modifications of m_path are all
of the form:
strncpy(exp->m_export.m_path, exp->m_export.e_path,
sizeof (exp->m_export.m_path) - 1);
exp->m_export.m_path[sizeof (exp->m_export.m_path) - 1] = '\0';
So m_path is always just a copy of e_path. In places where we need to
store a path to a submount of a CROSSMNT-exported filesystem, as in
cache.c, we just use a local variable.

It appears that this is used only by unfsd, and is obscure enough that
we should be able to just rip it out with no special precautions.

* support/export/nfsctl.c (expsetup): Don't export entries that
specify id mappings not supported by the kernel. No extant kernel
supports any significant mapping, only 'identity' (i.e. none).
When other mappings are supported, this code will need changing.
* debian/changelog: Version 1.0-2.
