Lots of work and analysis by "xbx___" in bug #1431750
(http://curl.haxx.se/bug/view.cgi?id=1431750) helped me identify and fix two
different but related bugs:

1) Removing an easy handle from a multi handle before the transfer is done
could leave a connection in the connection cache for that handle that is
in a state that isn't suitable for re-use. A subsequent re-use could then
read from a NULL pointer and segfault.

2) When an easy handle was removed from the multi handle, there could be an
outstanding c-ares DNS name resolve request. When the response arrived,
it caused havoc since the connection struct it "belonged" to could've
been freed already.

Now Curl_done() is called when an easy handle is removed from a multi handle
pre-maturely (that is, before the transfer was complteted). Curl_done() also
makes sure to cancel all (if any) outstanding c-ares requests.

Fixed test case 57 (KNOWN_BUG #18)

Fixed some spelling errors in comments, and extraneous \n in failf logs.

two typos in comments

Peter Su added support for SOCKS4 proxies. Enable this by setting the proxy
type to the already provided type CURLPROXY_SOCKS4.
I added a --socks4 option that works like the current --socks5

instead use the socks4 protocol.

Shmulik Regev fixed an issue with multi-pass authentication and compressed
content when libcurl didn't honor the internal ignorebody flag.

Fix spacing.

fixed formatting

Shmulik Regev provided a fix for the DNS cache when using short life times,
as previously it could be holding on to old cached entries longer than
requested.

Gopher is no longer supported.

32. (At least on Windows) If libcurl is built with c-ares and there's no DNS
server configured in the system, the ares_init() call fails and thus
curl_easy_init() fails as well. This causes weird effects for people who use
numerical IP addresses only.

Karl M added the CURLOPT_CONNECT_ONLY and CURLINFO_LASTSOCKET options that
an app can use to let libcurl only connect to a remote host and then extract
the socket from libcurl. libcurl will then not attempt to do any transfer at
all after the connect is done.

Kent Boortz improved the configure check for GnuTLS to properly set LIBS
instead of LDFLAGS.

CURLOPT_NOSIGNAL might be a MUST to make threaded use work, like on AIX 5.2
due to the use of the static variable for sigsetjmp()

Philippe Vaucher provided a brilliant piece of test code that show a problem
with re-used FTP connections. If the second request on the same connection was
set not to fetch a "body", libcurl could get confused and consider it an
attempt to use a dead connection and would go acting mighty strange.
