Proxy NTLM authentication should compare credentials when
re-using a connection similar to host authentication, as it
authenticate the connection.
Example:
curl -v -x http://proxy:port http://host/ -U good_user:good_pwd
--proxy-ntlm --next -x http://proxy:port http://host/
[-U fake_user:fake_pwd --proxy-ntlm]

- Switch from verifying a pinned public key in a callback during the
certificate verification to inline after the certificate verification.
The callback method had three problems:
1. If a pinned public key didn't match, CURLE_SSL_PINNEDPUBKEYNOTMATCH
was not returned.
2. If peer certificate verification was disabled the pinned key
verification did not take place as it should.
3. (related to #2) If there was no certificate of depth 0 the callback
would not have checked the pinned public key.
Though all those problems could have been fixed it would have made the
code more complex. Instead we now verify inline after the certificate
verification in mbedtls_connect_step2.

The CURLOPT_SSH_PUBLIC_KEYFILE option has been documented to handle
empty strings specially since curl-7_25_0-31-g05a443a but the behavior
was unintentionally removed in curl-7_38_0-47-gfa7d04f.
This commit restores the original behavior and clarifies it in the
documentation that NULL and "" have both the same meaning when passed
to CURLOPT_SSH_PUBLIC_KEYFILE.

... by extracting the LIB + REASON from the OpenSSL error code. OpenSSL
1.1.0+ returned a new func number of another cerfificate fail so this
required a fix and this is the better way to catch this error anyway.

When an HTTP/2 upgrade request fails (no protocol switch), it would
previously detect that as still possible to pipeline on (which is
acorrect) and do that when PIPEWAIT was enabled even if pipelining was
not explictily enabled.
It should only pipelined if explicitly asked to.

Before this patch, if a URL does not start with the protocol
name/scheme, effective URLs would be prefixed with upper-case protocol
names/schemes. This behavior might not be expected by library users or
end users.
For example, if `CURLOPT_DEFAULT_PROTOCOL` is set to "https". And the
URL is "hostname/path". The effective URL would be
"HTTPS://hostname/path" instead of "https://hostname/path".
After this patch, effective URLs would be prefixed with a lower-case
protocol name/scheme.

Previously, when HTTP/2 is enabled and used, and stream has content
length known, Curl_read was not called when there was no bytes left to
read. Because of this, we could not make sure that
http2_handle_stream_close was called for every stream. Since we use
http2_handle_stream_close to emit trailer fields, they were
effectively ignored. This commit changes the code so that Curl_read is
called even if no bytes left to read, to ensure that
http2_handle_stream_close is called for every stream.

This regression landed in 5778e6f5 and made libcurl not act on received

To make sure curl doesn't allow multiplexing before a connection is
upgraded to HTTP/2 (like when Upgrade: h2c fails), we must make sure the
connection uses HTTP/2 as well and not only check what's wanted.

Previously file.txt[CR][LF] would have been returned as file.tx
(without the last t) if filetype is symlink. Now the t is
included and the internal item_length includes the zero byte.

Try harder to prevent libcurl from opening up an additional socket when

The function is only present in wolfssl/cyassl if it was built with

unless the TLS lib has that function available.
Also fix the mistake in configure that checks for the wrong lib name.

This commit adds trailer support in HTTP/2. In HTTP/1.1, chunked
encoding must be used to send trialer fields. HTTP/2 deprecated any
trandfer-encoding, including chunked. But trailer fields are now
always available.
Since trailer fields are relatively rare these days (gRPC uses them
extensively though), allocating buffer for trailer fields is done when
we detect that HEADERS frame containing trailer fields is started. We
use Curl_add_buffer_* functions to buffer all trailers, just like we
do for regular header fields. And then deliver them when stream is
closed. We have to be careful here so that all data are delivered to
upper layer before sending trailers to the application.
We can deliver trailer field one by one using NGHTTP2_ERR_PAUSE
mechanism, but current method is far more simple.
Another possibility is use chunked encoding internally for HTTP/2
traffic. I have not tested it, but it could add another overhead.
Closes #564

When NGHTTP2_ERR_PAUSE is returned from data_source_read_callback, we
might not process DATA frame fully. Calling nghttp2_session_mem_recv()
again will continue to process DATA frame, but if there is no incoming
frames, then we have to call it again with 0-length data. Without this,
on_stream_close callback will not be called, and stream could be hanged.

The name of the header guard in lwIP's <lwip/opt.h> has changed from
'__LWIP_OPT_H__' to 'LWIP_HDR_OPT_H' (bug #35874 in May 2015).
Other fixes:
- In curl_setup.h, the problem with an old PSDK doesn't apply if lwIP is
used.
- In memdebug.h, the 'socket' should be undefined first due to lwIP's
lwip_socket() macro.
- In curl_addrinfo.c lwIP's getaddrinfo() + freeaddrinfo() macros need
special handling because they were undef'ed in memdebug.h.
- In select.c we can't use preprocessor conditionals inside select if
MSVC and select is a macro, as it is with lwIP.

- If the size of the length type (curl_off_t) is greater than the size
of the size_t type then check before allocating memory to make sure the
value of length will fit in a size_t without overflow. If it doesn't
then return CURLE_BAD_FUNCTION_ARGUMENT.

The RTSP code path didn't skip adding the if-modified-since for certain
RTSP code paths, even if CURLOPT_TIMECONDITION was set to
CURL_TIMECOND_NONE.
Also, an unknown non-zero CURLOPT_TIMECONDITION value no longer equals
CURL_TIMECOND_IFMODSINCE.

It would previously be skipped if an existing error was returned, but
would lead to a previous value being left there and later used.
CURLINFO_TOTAL_TIME for example.
Still it avoids that final progress update if we reached DONE as the
result of a callback abort to avoid another callback to be called after
an abort-by-callback.
