Using sftp to delete a file with CURLOPT_NOBODY set with a reused

The information extracted from the server certificates in step 3 is only

SSL_CTX_add_extra_chain_cert takes ownership of the given certificate
while, despite the similar name, SSL_CTX_add_client_CA does not. Thus
it's best to call SSL_CTX_add_client_CA before
SSL_CTX_add_extra_chain_cert, while the code still has ownership of the
argument.

In addition to unix domain sockets, Linux also supports an
abstract namespace which is independent of the filesystem.
In order to support it, add new CURLOPT_ABSTRACT_UNIX_SOCKET

Under condition using http_proxy env var, noproxy list was the
combination of --noproxy option and NO_PROXY env var previously. Since
this commit, --noproxy option overrides NO_PROXY environment variable
even if use http_proxy env var.
Closes#1140
If defined CURL_DISABLE_HTTP, detect_proxy() returned NULL. If not
defined CURL_DISABLE_HTTP, detect_proxy() checked noproxy list.
Thus refactor to set proxy to NULL instead of calling detect_proxy() if
define CURL_DISABLE_HTTP, and refactor to call detect_proxy() if not
define CURL_DISABLE_HTTP and the host is not in the noproxy list.
The combination of --noproxy option and http_proxy env var works well
both for proxied hosts and non-proxied hosts.
However, when combining NO_PROXY env var with --proxy option,
non-proxied hosts are not reachable while proxied host is OK.
This patch allows us to access non-proxied hosts even if using NO_PROXY
env var with --proxy option.

Fixes a few issues in manual wildcard cert name validation in
schannel support code for Win32 CE:
- when comparing the wildcard name to the hostname, the wildcard
character was removed from the cert name and the hostname
was checked to see if it ended with the modified cert name.
This allowed cert names like *.com to match the connection
hostname. This violates recommendations from RFC 6125.
- when the wildcard name in the certificate is longer than the
connection hostname, a buffer overread of the connection
hostname buffer would occur during the comparison of the
certificate name and the connection hostname.
It doesn't benefit us much as the connection could get closed at
any time, and also by checking we lose the ability to determine
if the socket was closed by reading zero bytes.

CURLOPT_SOCKS_PROXY -> CURLOPT_PRE_PROXY
Added the corresponding --preroxy command line option. Sets a SOCKS
proxy to connect to _before_ connecting to a HTTP(S) proxy.
This was added as part of the SOCKS+HTTPS proxy merge but there's no
need to support this as we prefer to have the protocol specified as a
prefix instead.
ERR_PACK is an internal detail of OpenSSL. Also, when using it, a
function name must be specified which is overly specific: the test will
break whenever OpenSSL internally change things so that a different
function creates the error.

Since it now reads responses one byte a time, a loop could be removed

* HTTPS proxies:
An HTTPS proxy receives all transactions over an SSL/TLS connection.
Once a secure connection with the proxy is established, the user agent
uses the proxy as usual, including sending CONNECT requests to instruct
the proxy to establish a [usually secure] TCP tunnel with an origin
server. HTTPS proxies protect nearly all aspects of user-proxy
communications as opposed to HTTP proxies that receive all requests
(including CONNECT requests) in vulnerable clear text.
With HTTPS proxies, it is possible to have two concurrent _nested_
SSL/TLS sessions: the "outer" one between the user agent and the proxy
and the "inner" one between the user agent and the origin server
(through the proxy). This change adds supports for such nested sessions
as well.
A secure connection with a proxy requires its own set of the usual SSL
options (their actual descriptions differ and need polishing, see TODO):
--proxy-cacert FILE CA certificate to verify peer against
--proxy-capath DIR CA directory to verify peer against
--proxy-cert CERT[:PASSWD] Client certificate file and password
--proxy-cert-type TYPE Certificate file type (DER/PEM/ENG)
--proxy-ciphers LIST SSL ciphers to use
--proxy-crlfile FILE Get a CRL list in PEM format from the file
--proxy-insecure Allow connections to proxies with bad certs
--proxy-key KEY Private key file name
--proxy-key-type TYPE Private key file type (DER/PEM/ENG)
--proxy-pass PASS Pass phrase for the private key
--proxy-ssl-allow-beast Allow security flaw to improve interop
--proxy-sslv2 Use SSLv2
--proxy-sslv3 Use SSLv3
--proxy-tlsv1 Use TLSv1
--proxy-tlsuser USER TLS username
--proxy-tlspassword STRING TLS password
--proxy-tlsauthtype STRING TLS authentication type (default SRP)
All --proxy-foo options are independent from their --foo counterparts,
except --proxy-crlfile which defaults to --crlfile and --proxy-capath
which defaults to --capath.
Curl now also supports %{proxy_ssl_verify_result} --write-out variable,
similar to the existing %{ssl_verify_result} variable.
Supported backends: OpenSSL, GnuTLS, and NSS.
* A SOCKS proxy + HTTP/HTTPS proxy combination:
If both --socks* and --proxy options are given, Curl first connects to
the SOCKS proxy and then connects (through SOCKS) to the HTTP or HTTPS
proxy.
TODO: Update documentation for the new APIs and --proxy-* options.
Look for "Added in 7.XXX" marks.

This should fix the "warning: 'curl_strequal' redeclared without

link error on Windows because of the missing CURL_EXTERN on the

These two public functions have been mentioned as deprecated since a
very long time but since they are still part of the API and ABI we need
to keep them around.
... to make it less likely that we forget that the function actually
does case insentive compares. Also replaced several invokes of the
function with a plain strcmp when case sensitivity is not an issue (like
comparing with "-").
If the requested size is zero, bail out with error instead of doing a
realloc() that would cause a double-free: realloc(0) acts as a free()
and then there's a second free in the cleanup path.

Curl_select_ready() was the former API that was replaced with

level also have that bit set, and we need to consider pipelining
possible on those connections.

pipelining. Prior to this change connections marked for deletion (e.g.
timeout) would be erroneously used, resulting in sporadic crashes.
As originally reported and fixed by Carlo Wood (origin unknown).

Not all reply messages were properly checked for their lengths, which
made it possible to access uninitialized memory (but this does not lead
to out of boundary accesses).

... it no longer takes printf() arguments since it was only really taken
advantage by one user and it was not written and used in a safe
way. Thus the 'f' is removed from the function name and the proto is
changed.
Although the current code wouldn't end up in badness, it was a risk that
future changes could end up springf()ing too large data or passing in a
format string inadvertently.
The previous use of snprintf() could make libcurl silently truncate some
input data and not report that back on overly large input, which could
make data get sent over the network in a bad format.
Example:
$ curl --form 'a=b' -H "Content-Type: $(perl -e 'print "A"x4100')"
Cokie with the same domain but different tailmatching property are now
considered different and do not replace each other. If header contains
following lines then two cookies will be set: Set-Cookie: foo=bar;
domain=.foo.com; expires=Thu Mar 3 GMT 8:56:27 2033 Set-Cookie: foo=baz;
domain=foo.com; expires=Thu Mar 3 GMT 8:56:27 2033
This matches Chrome, Opera, Safari, and Firefox behavior. When sending
stored tokens to foo.com Chrome, Opera, Firefox store send them in the
stored order, while Safari pre-sort the cookies.

Add the new option CURLOPT_KEEP_SENDING_ON_ERROR to control whether
sending the request body shall be completed when the server responds
early with an error status code.
This is suitable for manual NTLM authentication.

As it seems to be a rarely used cipher suite (for securely established
but _unencrypted_ connections), I believe it is fine not to provide an
alias for the misspelled variant.
LibreSSL defines `OPENSSL_VERSION_NUMBER` as `0x20000000L` for all
versions returning `LibreSSL/2.0.0` for any LibreSSL version.
This change provides a local OpenSSL_version_num function replacement
returning LIBRESSL_VERSION_NUMBER instead.
Closes#1029
