... even for those that don't support providing anything in the
'internals' struct member since it offers a convenient way for
applications to figure this out.
If the port number in the proxy string ended weirdly or the number is
too large, skip it. Mostly as a means to bail out early if a "bare" IPv6
numerical address is used without enclosing brackets.
Also mention the bracket requirement for IPv6 numerical addresses to the
man page for CURLOPT_PROXY.

- Warn that cookies without a domain are sent to any domain:
CURLOPT_COOKIELIST, CURLOPT_COOKIEFILE, --cookie
- Note that imported Set-Cookie cookies without a domain are no longer
exported:
CURLINFO_COOKIELIST, CURLOPT_COOKIEJAR, --cookie-jar
- Add new option CURLOPT_DEFAULT_PROTOCOL to allow specifying a default
protocol for schemeless URLs.
- Add new tool option --proto-default to expose
CURLOPT_DEFAULT_PROTOCOL.
In the case of schemeless URLs libcurl will behave in this way:
When the option is used libcurl will use the supplied default.
When the option is not used, libcurl will follow its usual plan of
guessing from the hostname and falling back to 'http'.
- Clarify that FILE and SCP are disabled by default since 7.19.4
- Add that SMB and SMBS are disabled by default since 7.40.0
- Add CURLPROTO_SMBS to the list of protocols
New tool option --ssl-no-revoke.
New value CURLSSLOPT_NO_REVOKE for CURLOPT_SSL_OPTIONS.
Currently this option applies only to WinSSL where we have automatic
certificate revocation checking by default. According to the
ssl-compared chart there are other backends that have automatic checking
(NSS, wolfSSL and DarwinSSL) so we could possibly accommodate them at
some later point.

Prior to this change any-domain cookies (cookies without a domain that
are sent to any domain) were exported with domain name "unknown".
Bug: https://github.com/bagder/curl/issues/292
Document that if Set-Cookie is used without a domain then the cookie is
sent for any domain and will not be modified.

The CURLOPT_COOKIE doc says it "sets the cookie header explicitly in the
outgoing request(s)." However there seems to be some user confusion
about cookie modification. Document that the cookies set by this option
are not modified by the cookie engine.

Make the HTTP headers separated by default for improved security and
reduced risk for information leakage.

Icecast versions 1.3.0 through 1.3.12 would reply with "ICY 200"
under certain conditions:
client_wants_icy_headers (connection_t *con)
{
const char *val;
if (!con)
return 1;
val = get_user_agent (con);
if (!val || !val[0] || strcmp (val, "(null)") == 0)
return 1;
if (con->food.client->use_icy)
return 1;
if (strncasecmp (val, "winamp", 6) == 0)
return 1;
if (strncasecmp (val, "Shoutcast", 9) == 0)
return 1;
return 0;
}
So mainly if there is no 'user agent' or it is '(null)' or contains
'winamp' or 'Shoutcast'.
No mainstream distribution carries Icecast 1.3.x anymore, after all
it was released in 2002 and superseded by Icecast 2.x.
This option can be used to enable/disable certificate status verification using
the "Certificate Status Request" TLS extension defined in RFC6066 section 8.
This also adds the CURLE_SSL_INVALIDCERTSTATUS error, to be used when the
certificate status verification fails, and the Curl_ssl_cert_status_request()
function, used to check whether the SSL backend supports the status_request
extension.
Change CURLOPT_TIMEOUT doc to warn that if CURLOPT_TIMEOUT and
CURLOPT_TIMEOUT_MS are both set whichever one is set last is the one
that will be used.
Prior to this change that behavior was only noted in the
CURLOPT_TIMEOUT_MS doc.
Add .nf and .fi such that the code gets wrapped in a pre on the web.
Fixed grammar, fixed formatting of the "See also" items.

The ability to do HTTP requests over a UNIX domain socket has been
requested before, in Apr 2008 [0][1] and Sep 2010 [2]. While a
discussion happened, no patch seems to get through. I decided to give it
a go since I need to test a nginx HTTP server which listens on a UNIX
domain socket.
One patch [3] seems to make it possible to use the
CURLOPT_OPENSOCKETFUNCTION function to gain a UNIX domain socket.
Another person wrote a Go program which can do HTTP over a UNIX socket
for Docker[4] which uses a special URL scheme (though the name contains
cURL, it has no relation to the cURL library).
This patch considers support for UNIX domain sockets at the same level
as HTTP proxies / IPv6, it acts as an intermediate socket provider and
not as a separate protocol. Since this feature affects network
operations, a new feature flag was added ("unix-sockets") with a
corresponding CURL_VERSION_UNIX_SOCKETS macro.
A new CURLOPT_UNIX_SOCKET_PATH option is added and documented. This
option enables UNIX domain sockets support for all requests on the
handle (replacing IP sockets and skipping proxies).
A new configure option (--enable-unix-sockets) and CMake option
(ENABLE_UNIX_SOCKETS) can disable this optional feature. Note that I
deliberately did not mark this feature as advanced, this is a
feature/component that should easily be available.

- Remove SSLv3 from SSL default in darwinssl, schannel, cyassl, nss,
openssl effectively making the default TLS 1.x. axTLS is not affected
since it supports only TLS, and gnutls is not affected since it already
defaults to TLS 1.x.
- Update CURLOPT_SSLVERSION doc
Option --pinnedpubkey takes a path to a public key in DER format and
only connect if it matches (currently only implemented with OpenSSL).
Provides CURLOPT_PINNEDPUBLICKEY for curl_easy_setopt().
Extract a public RSA key from a website like so:
openssl s_client -connect google.com:443 2>&1 < /dev/null | \
sed -n '/-----BEGIN/,/-----END/p' | openssl x509 -noout -pubkey \
| openssl rsa -pubin -outform DER > google.com.der
When enabling CURLOPT_NOBODY, libcurl effectively switches off upload
mode and will do a download (without a body). This is now better
explained in this man page.

This repeats what has already been documented in both the curl manpage
and CURLOPT_USERPWD documentation but is provided here for completeness
as someone may not especially read the latter when using libcurl.
Added information about Kerberos V5 requiring the domain part in the
user name.
Mentioned that the user name can be specified in UPN format, and not
just in Down-Level Logon Name format, following the information
added in commit 7679cb3fa8 reworking the exisitng information in the
process.
