completely disable that header to get sent.

Location: following takes "us" to other servers that should not get the
user and password

on those occations

function to get called in the curl_close() function for cleanup
auth_host is added to store the original (first) host name used

allow the connect function to better deal with timeouts, as was just added
to ftp

thus enables timeout if the server doesn't respond within the proper time.

Added a missing free() in curl_disconnect()
Made (https) connect errors abort better and earlier

transfer

removed the "mode" concept
moved all #-stuff to the client

I also use typecasted size_t now for systems with unsigned such ones

now returns -1 from FormReader() when the last form data has been read!

files depend on that as well. It turned out Borland has no unistd.h file
either, only mingw32 seems to use that.
