Restore the behaviour of not setting errno to ENOMEM when allocating 0

units of storage and returning a null pointer in System V mode; this was
broken by the `fix' in rev. 1.24. Also, as it is stated in ISO C that
such operation does not constitute an allocation failure, do not abort()
even if the `X' option is set.
Amusingly enough the SVID, Fourth Edition, specifies the `unique pointer'
return behaviour for this kind of allocation, so this is kind of mis-named.

* There was an off-by-one error that caused the addition of a NUL or slash in fts_build() to

* After fts_palloc(), we need to reset `cp' so that it points to the new path name buffer;
otherwise the addition of the file name before calling fts_stat() could lose.
Also, fix stupidity in the fts_palloc() interface. We don't want N bytes more than the
current buffer size; we want N bytes more than the current length. Just pass in the new
size, since we can't figure it out easily here.

- do not make query for AFs that are not supported by kernel.
...
i.e. do not make query for IPv6 addresses, when running on non-IPv6 kernel,
or, do not query for IPv4 address on IPv6-only kernel :-)
This kind of behavior is not very well documented in RFC2553. This
may violate the spec.
- on EAI_AGAIN, only retry 3 times (3 is a magic number). Previous code
made retries forever. This solves situation where name server is wrongly
configured and nameserver:53 returns icmp port unreach.
The only proper fix for all getaddrinfo() related twists would be to
implement getipnodebyname() and get rid of wacky get_addr().
We need to contribute bind8 development for this.

Clean up this mess a lot. I believe we still have the following
...
issues (at least):
1) sbrk is defined as returning char *, which violates XPG
2) I'm not clear on what happens if you try to sbrk() on a negative
incr that is less than the page size. I'm guessing "nothing", but we
should document this behavior.
3) XPG says some interesting things about whether new pages are
guaranteed zeroed. We say nothing about this. We should document our
behavior.
4) It isn't clear if *we* guarantee that malloc and sbrk can be mixed
in our API (I've documented that it isn't universally portable.)
We really should clean these up, too.

add IPv6 support functions.

get{addr,name} info are implemented to have as little impact to existing
resolver code as possible, so they are NOT the optimal implementation.
They are at this moment not very thread safe (as they call
gethostby{name,addr}).

gethostby{name,addr}.
