When libcurl has said to the server that there's a POST or PUT coming
(with a content-length and all) it has to either deliver that amount of
data or it needs to close the connection before trying a second request.
Adds test case 1129, 1130 and 1131
The bug report is about when used with 100-continue, but the change is
more generic.

Made several functions static
Made one function defined to nothing when RTSP is disabled to avoid
the #ifdefs in code.
Removed explicit rtsp.h includes
libcurl failed to check the correct struct for HTTPS after CONNECT was
issued to the proxy, so it didn't do the TLS handshake and subsequently
failed the connection. A regression released in 7.21.5 (introduced
around commit 8831000bc0).

Added CURLOPT_TRANSFER_ENCODING as the option to set to request Transfer
Encoding in HTTP requests (if built zlib enabled). I also renamed
CURLOPT_ENCODING to CURLOPT_ACCEPT_ENCODING (while keeping the old name
around) to reduce the confusion when we have to encoding options for
HTTP.
--tr-encoding is now the new command line option for curl to request
this, and thus I updated the test cases accordingly.
When TE: is inserted in the request, we must add a "Connection: TE" as
well to be HTTP 1.1 compliant. If a custom Connection: header is passed
in, we must use that and only append TE to it. Test case 1125 verifies
TE: + custom Connection:.
Since this struct member is used in the code to determine what and how
to decode automatically and since it is now also used for compressed
Transfer-Encodings, I renamed it to the more suitable 'auto_decoding'
Transfer-Encoding differs from Content-Encoding in a few subtle ways,
but primarily it concerns the transfer only and not the content so when
discovered to be compressed we know we have to uncompress it. There will
only arrive compressed transfers in a response after we have requested
them with the appropriate TE: header.
Test case 1122 and 1123 verify.
The new http_proxy.* files now host HTTP proxy specific code (500+ lines
moved out from http.c), and as a consequence there is a macro introduced
for the Curl_proxyCONNECT() function so that code can use it without
actually supporting proxy (or HTTP) in builds.
The PROT_* set of internal defines for the protocols is no longer
used. We now use the same bits internally as we have defined in the
public header using the CURLPROTO_ prefix. This is for simplicity and
because the PROT_* prefix was already used duplicated internally for a
set of KRB4 values.
The PROTOPT_* defines were moved up to just below the struct definition
within which they are used.
The protocol handler struct got a 'flags' field for special information
and characteristics of the given protocol.
This now enables us to move away central protocol information such as
CLOSEACTION and DUALCHANNEL from single defines in a central place, out
to each protocol's definition. It also made us stop abusing the protocol
field for other info than the protocol, and we could start cleaning up
other protocol-specific things by adding flags bits to set in the
handler struct.
The "protocol" field connectdata struct was removed as well and the code
now refers directly to the conn->handler->protocol field instead. To
make things work properly, the code now always store a conn->given
pointer that points out the original handler struct so that the code can
learn details from the original protocol even if conn->handler is
modified along the way - for example when switching to go over a HTTP
proxy.
Make GSS authentication work when a curl handle is reused for multiple
authenticated requests, by always setting negdata->state in
output_auth_headers().

Instead of polluting many places with #ifdefs, we create a single place
for this function, and also check return code properly so that a NULL
pointer returned won't cause problems.
The HTTP parser allocated memory on each received Location: header
without properly freeing old data. Starting now, the code only considers
the first Location: header and will blissfully ignore subsequent ones.

Added axTLS to autotool files and glue code to misc other files.
axtls.h maps SSL API functions, but may change.
axtls.c is just a stub file and will definitely change.
When given a custom host name in a Host: header, we can use it for
several different purposes other than just cookies, so we rename it and
use it for SSL SNI etc.
When failing to build form post due to an error, the code now does a
proper failf(). Previously libcurl would report an error like "failed
creating formpost data" when a file wasn't possible to open which was
not easy for users to figure out.
I also lower cased a function name to be named more curl-style and
removed some unnecessary code.
It was pointed out that the special case libcurl did for 416 was
incorrect and wrong. 416 is not really different to other errors so the
response body must be handled like for other errors/http responses.

HTTP allows that a server sends trailing headers after all the chunks
have been sent WITHOUT signalling their presence in the first response
headers. The "Trailer:" header is only a SHOULD there and as we need to
handle the situation even without that header I made libcurl ignore
Trailer: completely.
Test case 1116 was added to verify this and to make sure we handle more
than one trailer header properly.

Win64's 32 bit long but 64 bit size_t caused a warning that we avoid

As mentioned in bug report #2956968, the HTTP code wouldn't send the
first empty chunk during the auth negotiation phase of the HTTP request
sending, so the server would wait for data to come and libcurl would
wait for data to arrive... I've made the code not enable chunked
encoding until the auth negotiation is done and thus this scenario
doesn't occur anymore.

Howard Chu brought the bulk work of this patch that properly
moves out the sending and recving of data to the parts of the
code that are properly responsible for the various ways of doing
so.
Daniel Stenberg assisted with polishing a few bits and fixed some
minor flaws in the original patch.
Another upside of this patch is that we now abuse CURLcodes less
with the "magic" -1 return codes and instead use CURLE_AGAIN more
consistently.
This is Hoi-Ho Chan's patch with some minor fixes by me. There
are some potential issues in this, but none worse than we can
sort out on the list and over time.
Akos Pasztory filed debian bug report #572276http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=572276
mentioning a problem with a resource that returns chunked-encoded
_and_ with a Content-Length and libcurl failed to properly ignore
the latter information.
curl_easy_setopt with CURLOPT_HTTPHEADER, the library should set
data->state.expect100header accordingly - the current code (in 7.19.7 at
least) doesn't handle this properly. Martin Storsjo provided the fix!
POST using a read callback, with Digest authentication and
"Transfer-Encoding: chunked" enforced. I would then cause the first request
to be wrongly sent and then basically hang until the server closed the
connection. I fixed the problem and added test case 565 to verify it.

made libcurl loop infinitely when given incorrect credentials when using HTTP
GSS negotiate authentication.
(http://curl.haxx.se/bug/view.cgi?id=2813123) and an a patch that fixes the
problem:
Url A is accessed using auth. Url A redirects to Url B (on a different
server0. Url B reuses a persistent connection. Url B has auth, even though
it's on a different server.
Note: if Url B does not reuse a persistent connection, auth is not sent.
is almost always a VERY BAD IDEA. Yet there are still apps out there doing
this, and now recently it triggered a bug/side-effect in libcurl as when
libcurl sends a POST or PUT with NTLM, it sends an empty post first when it
knows it will just get a 401/407 back. If the app then replaced the
Content-Length header, it caused the server to wait for input that libcurl
wouldn't send. Aaron Oneal reported this problem in bug report #2799008http://curl.haxx.se/bug/view.cgi?id=2799008) and helped us verify the fix.

as reported by Ebenezer Ikonne (on curl-users) and Laurent Rabret (on
curl-library). The transfer was mistakenly marked to get more data to send
but since it didn't actually have that, it just hung there...
Chen pointed out how curl couldn't upload with resume when reading from a
pipe.
This ended up with the introduction of a new return code for the
CURLOPT_SEEKFUNCTION callback that basically says that the seek failed but
that libcurl may try to resolve the situation anyway. In our case this means
libcurl will attempt to instead read that much data from the stream instead
of seeking and that way curl can now upload with resume when data is read
from a stream!
version 1.1 instead of 1.0 like before. This change also introduces the new
proxy type for libcurl called 'CURLPROXY_HTTP_1_0' that then allows apps to
switch (back) to CONNECT 1.0 requests. The curl tool also got a --proxy1.0
option that works exactly like --proxy but sets CURLPROXY_HTTP_1_0.
I updated all test cases cases that use CONNECT and I tried to do some using
--proxy1.0 and some updated to do CONNECT 1.1 to get both versions run.

to fail in the Turkish locale when CURLOPT_PROXY_TRANSFER_MODE is
used (test case 561)
Added tests 561 and 1092 through 1094 to test various combinations
of ;type= and ;mode= URLs that could potentially fail in the Turkish
locale.
now has an improved ability to do right when the multi interface (both
"regular" and multi_socket) is used for SCP and SFTP transfers. This should
result in (much) less busy-loop situations and thus less CPU usage with no
speed loss.
(http://curl.haxx.se/bug/view.cgi?id=2221237) that identified an infinite
loop during GSS authentication given some specific conditions. With his
patience and great feedback I managed to narrow down the problem and
eventually fix it although I can't test any of this myself!
(http://curl.haxx.se/bug/view.cgi?id=2255627) which pointed out that a
program using libcurl's multi interface to download a HTTPS page with a
libcurl built powered by OpenSSL, would easily get silly and instead hand
over SSL details as data instead of the actual HTTP headers and body. This
happened because libcurl would consider the connection handshake done too
early. This problem was introduced at September 22nd 2008 with my fix of the
bug #2107377
The correct fix is now instead done within the GnuTLS-handling code, as both
the OpenSSL and the NSS code already deal with this situation in similar
fashion. I added test case 560 in an attempt to verify this fix, but
unfortunately it didn't trigger it even before this fix!
Changed checkprefix() to use it and those instances of strnequal() that
compare host names or other protocol strings that are defined to be
independent of case in the C locale. This should fix a few more
Turkish locale problems.
(http://curl.haxx.se/bug/view.cgi?id=2154627) which pointed out that libcurl
uses strcasecmp() in multiple places where it causes failures when the
Turkish locale is used. This is because 'i' and 'I' isn't the same letter so
strcasecmp() on those letters are different in Turkish than in English (or
just about all other languages). I thus introduced a totally new internal
function in libcurl (called Curl_ascii_equal) for doing case insentive
comparisons for english-(ascii?) style strings that thus will make "file"
and "FILE" match even if the Turkish locale is selected.
proxy" (http://curl.haxx.se/bug/view.cgi?id=2107377) that showed how a multi
interface using program didn't work when built with GnuTLS and a CONNECT
request was done over a proxy (basically test 502 over a proxy to a HTTPS
site). It turned out the ssl connect function would get called twice which
caused the second call to fail.
