Avoid typecasting a signed char to an int when using is*() functions, as that
could very well cause a negate number get passed in and thus cause reading
outside of the array usually used for this purpose.

We avoid this by using the uppercase macro versions introduced just now that
does some extra crazy typecasts to avoid byte codes > 127 to cause negative
int values.

Explicit typecast for Curl_debug() size argument

Remove redundant __CYGWIN__ symbol check

Support for FTP third party transfers is now dropped

Compiler warning fix

Major overhaul introducing http pipelining support and shared connection
cache within the multi handle.

Simplified #ifdef on WIN32; the statement
" !defined(__GNUC__) || defined(__MINGW32__)" implies
CygWin.

Removed "#ifndef__WATCOMC__". Use "#ifdef HAVE_SYS_TIME_H" instead.

Watcom lacks <sys/time.h>.

David McCreedy fixed a remaining mistake from the August 19 TYPE change.

Based on a patch by Armel Asselin, the FTP code no longer re-issues the TYPE
command on subsequent requests on a re-used connection unless it has to.

Fixed a flaw in the "Expect: 100-continue" treatment. If you did two POSTs
on a persistent connection and allowed the first to use that header, you
could not disable it for the second request.

Silence warning: empty body in an if-statement

Georg Horn made the transfer timeout error message include more details

Peter Silva introduced CURLOPT_MAX_SEND_SPEED_LARGE and
CURLOPT_MAX_RECV_SPEED_LARGE that limit tha maximum rate libcurl is allowed

Peter Silva introduced CURLOPT_MAX_SEND_SPEED_LARGE and
CURLOPT_MAX_RECV_SPEED_LARGE that limit tha maximum rate libcurl is allowed
to send or receive data. This kind of adds the the command line tool's
option --limit-rate to the library.

The rate limiting logic in the curl app is now removed and is instead
provided by libcurl itself. Transfer rate limiting will now also work for -d
and -F, which it didn't before.

select_res is not a socket, it should be a plain int

oops, serious breakage in the fdset() function

David McCreedy brought line end conversions when doing FTP ASCII
transfers. They are done on non-windows systems and translate CRLF to LF.

First curl_multi_socket() commit. Should primarily be considered as an internal
code rearrange to fit the future better.

First commit of David McCreedy's EBCDIC and TPF changes.

#1451929 (http://curl.haxx.se/bug/view.cgi?id=1451929) detailed a bug that
occurred when asking libcurl to follow HTTP redirects and the original URL had
more than one question mark (?). Added test case 276 to verify.

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.

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.
