Use %HOSTIP:%HTTPPORT instead of 127.0.0.1:8990 so that
verification works if the baseport change option is used
when executing runtests.pl.

Clarified as it isn't used with a -D option for them.

Added "3.19 How do I get HTTP from a host using a specific IP address?"
and updated some stuff about certs etc.

The code reading chunked encoding attempts to rewind the code if it had
read more data than the chunky parser consumes. The rewinding can fail
and it will then cause an error. This change now makes the rewinding
only happen if pipelining is in use - as that's the only time it really
needs to be done.

Curl_getconnectinfo() is changed to return a proper curl_socket_t for
the last socket so that it'll work more portably (and cause less
compiler warnings).

Otherwise, there could be problems running in certain locales.

Adam Light posted this patch to the list which enables builds from
git with VC versions other than vc6; also he added a vc10 target.

Add a timeout check for handles in the state machine so that they will
timeout in all states disregarding what actions that may or may not
happen.

Fixed a bug in socket_action introduced recently when looping over timed
out handles: it wouldn't assign the 'data' variable and thus it wouldn't
properly take care of handles.

In the update_timer function, the code now checks if the timeout has
been removed and then it tells the application. Previously it would
always let the remaining timeout(s) just linger to expire later on.

Curl_expire() set to 0 expires ALL timeouts so it should only be called
if we truly and really want to remove all timeouts for the handle.

Make use of the helper function Curl_timeleft() instead of duplicating
code.

Each easy handle has a list of timeouts, so as soon as the main timeout
for a handle expires, we must make sure to get the next entry from the
list and re-add the handle to the splay tree.

This was attempted previously but was done poorly in my commit
232ad654.

When a new transfer is about to start we now set the proper timeouts to
expire for the multi interface if they are set for the handle. This is a
follow-up bugfix to make sure that easy handles timeout properly when
the times expire and the multi interface is used. This also improves
curl_multi_timeout().

'm4 version  found. You need a GNU m4 installed!' is a bit confusing.

Fixed some issues that caused xmllint failures, added features
and keywords, fixed some quotes and removed some <strip> sections
that unnecessarily limited test checking.

As the VC and RISCOS makefiles don't use the .inc file

Introduced in the initial gopher commits, there was added logic to do
GOPHER test serving in the pingpong server but as it resembles HTTP much
more than FTP or SMTP, the gopher testing has been moved over to instead
use the sws (HTTP) server. This change simply removes unused code.

Patches over email very easily lose CRLF line endings in files otherwise
LF-only so I had to put them back where needed.

The fix for the busyloop really only is a temporary work-around.  It
causes a BLOCKING behavior which is a NO-NO. This function should rather
be split up in a do and a doing piece where the pieces that aren't
possible to send now will be sent in the doing function repeatedly until
the entire request is sent.
