the definitions for the return type and arguments types of functions
recv() and send().

data is actually shown on screen. Like when you do 'curl -v host' with data
and debug info sent to the same terminal.

using winsock or winsock2 API.

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.

to the CURLOPT_DEBUGFUNCTION callback has been fixed (it was erroneously
included as part of the header).  A message was also added to the
command line tool to show when data is being sent, enabled when
--verbose is used.

encrypt the control connection and use the data connection "plain".

  handle that is part of a multi handle first removes the handle from the
  stack.

- Added CURLOPT_SSL_SESSIONID_CACHE and --no-sessionid to disable SSL
  session-ID re-use on demand since there obviously are broken servers out
  there that misbehave with session-IDs used.

HAVE_WINDOWS_H, HAVE_WINSOCK_H, HAVE_WINSOCK2_H, neither
HAVE_WS2TCPIP_H when __CYGWIN__ is defined.

control and data connection, as the existing --ftp-ssl option only requests
it.

tool option named --ftp-alternative-to-user. It provides a mean to send a
particular command if the normal USER/PASS approach fails.

Simplify check for NEED_MALLOC_H, and make more explicit that NEED_MALLOC_H shall be defined if <malloc.h> header file must be included even when including <stdlib.h>.

file: URLs only.

in libcurl as well, if necessary.

Prevent definition of HAVE_WINxxx_H symbols and avoid inclusion of Windows headers when compiled with Cygwin in POSIX emulation mode.

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.

typecast in the curl tool leading to a crash with (64bit?) VS2005 (at least)
since the struct timeval field tv_sec is an int while time_t is 64bit.
