The information about building with Kerberos4 support was half a year out
of date. We dropped support for that.

Added initial support for --next/-: which will be used to replace the
rather confusing : command line operation what was used for the URL
specific options prototype.

... and mention the --tlsv1.[0-2] options in the --tslv1 entry

... and edited language slightly

it is only WHILE added to a multi handle that it can't be used with the
easy interface

This feature specifies the availability of cryptographic
authentication, which can be disabled at compile-time

... since it is never returned since a long while back.

For the avoidance of doubt, show a domain which contains the no-proxy
pattern but not at the top level.

... for debug function

The word CURLOPT_PROXYPORT became detached from its sentence when the
note about the default was added.

Replaced the #define CURL_TIMEOUT_EXPECT_100 in transfer.c with the
CURLOPT_EXPECT_100_TIMEOUT_MS option to make the timeout configurable.

when using --http2 one can now selectively disable NPN or ALPN with
--no-alpn and --no-npn. for now honored with NSS only.

TODO: honor this option with GnuTLS and OpenSSL

The minor version will be dropped for HTTP 2 so it will make sense to
avoid using it in option names etc.

The list was out of date and the paragraph already refers to the
CURLOPT_HTTPAUTH explanation. All the auth bits are explained properly
there.

It also removes the ambiguity for what the "added" phrase refers to.
