105 - "invalid free after an http redirect to ftp"

https://bugzilla.novell.com/show_bug.cgi?id=332917 about a HTTP redirect to
FTP that caused memory havoc. His work together with my efforts created two
fixes:

#1 - FTP::file was moved to struct ftp_conn, because is has to be dealt with
     at connection cleanup, at which time the struct HandleData could be
     used by another connection.
     Also, the unused char *urlpath member is removed from struct FTP.

#2 - provide a Curl_reset_reqproto() function that frees
     data->reqdata.proto.* on connection setup if needed (that is if the
     SessionHandle was used by a different connection).

way:

93 - Digest for IIS fix (subject for removal)
100 - icc segmentation faults (subject for removal)

that specifying a proxy with a trailing slash didn't work (unless it also
contained a port number).

when assigning a NULL pointer to a function pointer var.

In CURL_CHECK_LIBS_WINLDAP and CURL_CHECK_LIBS_LDAP, check first with no
additional library even when the optional list of libraries has been given.

Specifically for linux x86-64 with Intel's icc.

icc warning level with libcurl's

may lose significant bits

failure condition: http://curl.haxx.se/mail/lib-2007-10/0152.html

when assigning a NULL pointer to a function pointer var.

and allow parameter specification of libraries to check.

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!".
