Fix a bug where fallback from AF_INET6 to AF_INET would not work properly together with relative search; if you had a search path of .a.com and .b.com, and foo.a.com would return ARES_ENODATA and foo.b.com would return ARES_ENOTFOUND, the lookup would not properly retry with AF_INET as it forgot the first ARES_ENODATA.

Don't confuse NUL with NULL.

CURLOPT_COPYPOSTFIELDS option added for dynamic.
Fix some OS400 features.

Fixed a typo in the LDAP configure code and made sure NULL is defined
in a test programs that need it.

My understanding is that we use "number" for discrete variables and
"amount" for continuous variables.

So you can say "The amount of flour required depends on..." or, "Last
night I consumed a large amount of beer!".

And, "That tank contains a large number of fish" or, "Over the week I
consumed a number of cases of beer."

I think that features are discrete, so the man page would read "...the
number of features will make your head spin!".

as subject for removal from this list (without any fix)

in the connectdata structure by a single handler table ptr.

Added support for skipping tests based on key words.

added check for MSVC6 standard PSDK and bail out since insufficient for LDAP support with current code.

behavior, it only changes the actual request method keyword and this is not
always what the user/app wants.

man page.

a response that was larger than 16KB is now improved slightly so that now
the restriction at 16KB is for the headers only and it should be a rare
situation where the response-headers exceed 16KB. Thus, I consider #47 fixed
and the header limitation is now known as known bug #48.
