The date format in RFC822 allows that the seconds part of HH:MM:SS is
left out, but this function didn't allow it. This change also includes a
modified test case that makes sure that this now works.

tftpd-hpa has a bug where it will send an incorrect ack when the block
counter wraps and tftp options have been sent. Work around that by
accepting an ack for 65535 when we're expecting one for 0.
- |fd| is now a curl_socket_t and |len| a size_t to avoid conversions.
- Added 2 FIXMEs about the 2 unsigned -> signed conversions.
- Included 2 minor changes to Curl_sec_end.
- Renamed it to do_sec_send as it is the function doing the actual
transfer.
- Do not return any values as no one was checking it and it never
reported a failure (added a FIXME about checking for errors).
- Renamed the variables to make their use more specific.
- Removed some casts (int -> curl_socket_t, ...)
- Avoid doing the htnl <-> nthl twice by caching the 2 results.
- Renamed the variables name to better match their intend.
- Unified the |decoded_len| checks.
- Added some FIXMEs to flag some improvement that did not go in this
change.
- Removed sec_prot_internal as it is now inlined in the function (this removed
a redundant check).
- Changed the prototype to return an error code.
- Updated the method to use the new ftp_send_command function.
- Added a level_to_char helper method to avoid relying on the compiler's
bound checks. This default to the maximum security we have in case of a
wrong input.
Tighten the type of the |data| parameter to avoid a cast. Also made
it const as we should not modify it.
Added a DEBUGASSERT on the size to be written while changing it.
To do so, made block_read call Curl_read_plain instead of read.
While changing them renamed block_read to socket_read and sec_get_data
to read_data to better match their function.
Also fixed a potential memory leak in block_read.
Obviously, browsers ignore a colon without a following port number. Both
Firefox and Chrome just removes the colon for such URLs. This change
does not remove the colon for URLs sent over a HTTP proxy, so we should
consider doing that change as well.

curl_easy_duphandle() was not properly duping the ares channel. The
ares_dup() function was introduced in c-ares 1.6.0 so by starting to use
this function we also raise the bar and require c-ares >= 1.6.0
(released Dec 9, 2008) for such builds.

If built without HTTP or proxy support it would cause a compiler warning
due to the unused variable. I moved the declaration of it into the only
scope it is used.
bool_false is the internal name used in the setup_once.h definition
we fall back to for non-C99 non-stdbool systems, it's not the actual
name to use in assignments (we use bool_false, bool_true there to
avoid global namespace problems, see comment in setup_once.h).
The correct C99 value to use is 'false', but let's use FALSE as
used elsewhere when assigning to bits.close. FALSE is set equal
to 'false' in setup_once.h when possible.
This fixes a build problem on C99 targets.
As of curl-7.21.1 tunnelling ldap queries through HTTP Proxies is not
supported. Actually if --proxytunnel command-line option (or equivalent
CURLOPT_HTTPPROXYTUNNEL) is used for ldap queries like
ldap://ldap.my.server.com/... You are unable to successfully execute the
query. In facts ldap_*_bind is executed directly against the ldap server
and proxy is totally ignored. This is true for both openLDAP and
Microsoft LDAP API.
Step to reproduce the error:
Just launch "curl --proxytunnel --proxy 192.168.1.1:8080
ldap://ldap.my.server.com/dc=... "
This fix adds an invocation to Curl_proxyCONNECT against the provided
proxy address and on successful "CONNECT" it tunnels ldap query to the
final ldap server through the HTTP proxy. As far as I know Microsoft
LDAP APIs don't permit tunnelling in any way so the patch provided is
for OpenLDAP only. The patch has been developed against OpenLDAP 2.4.23
and has been tested with Microsoft ISA Server 2006 and works properly
with basic, digest and NTLM authentication.
Rodric provide an awesome recipe that proved libcurl didn't timeout at
the requested time - it instead often timed out at [connect time] +
[timeout time] instead of the documented and intended [timeout time]
only. This bug was due to the code using the wrong base offset when
comparing against "now". I could also take the oppurtinity to simplify
the code by properly using of the generic help function for this:
Curl_timeleft.

Bug: http://curl.haxx.se/bug/view.cgi?id=3061535
As this function uses return code 0 to mean that there is no timeout, it
needs to check that it doesn't return a time left value that is exactly
zero. It could lead to libcurl doing an extra 1000 ms select() call and
thus not timing out as accurately as it should.
I fell over this bug when working on the bug 3061535 but this fix does
not correct that problem alone, although this is a problem that needs to
be fixed.

The timeout is set for the connect phase already at the start of the
request so we should not add a new one, and we MUST not set expire to 0
as that will remove any other potentially existing timeouts.
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).
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.
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
232ad6549a.
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().
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.
