Here's a stab at a consolidation of the SSL detection heuristics into
configure. Source files aren't changed by this patch, except for setup.h and
the various config*.h files.  Within the configure script, OPENSSL_ENABLED is
used to determine if SSL is being used or not, and outside configure,
USE_SSLEAY means the same thing; this could be even further unified some day.

Now, when SSL is not detected, configure skips the various checks that are
dependent on SSL, speeding up the configure process and avoiding complications
with cross compiles.  I also updated all the architecture- specific config
files I could see, but I couldn't test them.

- removal of getdate.c
- Added hostares.c, hostasyn.c, hostip4.c, hostip6.c, hostsync.c,
hostthre.c, inet_ntop.c, nwlib.c, parsedate.c, sterror.c, strtoofft.c

I have tested the build on 10.3, and will build on 10.2.8 in the next days.

libcurl always and unconditionally overwrote a stack-based array with 3 zero
bytes. I edited the fix to make it less likely to occur again (and added
a comment explaining the reason to the buffer size).

libcurl without cookie support. This is mainly useful if you want to build a
minimalistic libcurl with no cookies support at all. Like for embedded
systems or similar.

response. Previously, libcurl would re-resolve the host name with the new
port number and attempt to connect to that, while it should use the IP from
the control channel. This bug made it hard to EPSV from an FTP server with
multiple IP addresses!

at a chunk boundary it was not considered an error and thus went unnoticed.
Added test case 207 to verify.

CONNECT to a proxy with digest

(http://qa.mandrakesoft.com/show_bug.cgi?id=12285), when connecting to an
IPv6 host with FTP, --disable-epsv (or --disable-eprt) effectively disables
the ability to transfer a file. Now, when connected to an FTP server with
IPv6, these FTP commands can't be disabled even if asked to with the
available libcurl options.

clash with djgpp ioctl() macro in setup.h.

(http://qa.mandrakesoft.com/show_bug.cgi?id=12289), curl would print a newline
to "finish" the progress meter after each redirect and not only after a
completed transfer.

If EPSV, EPRT or LPRT is tried and doesn't work, it will not be retried on
the same server again even if a following request is made using a persistent
connection.

If a second request is made to a server, requesting a file from the same
directory as the previous request operated on, libcurl will no longer make
that long series of CWD commands just to end up on the same spot. Note that
this is only for *exactly* the same dir. There is still room for improvements
to optimize the CWD-sending when the dirs are only slightly different.

Added test 210, 211 and 212 to verify these changes. Had to improve the
test script too and added a new primitive to the test file format.

Shouldn't Curl_select() use curl_socket_t ?
