b5901cab57 http: Ignore HTTP/2 prior knowledge setting for HTTP proxies
- Do not switch to HTTP/2 for an HTTP proxy that is not tunnelling to
  the destination host.

We already do something similar for HTTPS proxies by not sending h2. [1]

Prior to this change setting CURL_HTTP_VERSION_2_PRIOR_KNOWLEDGE would
incorrectly use HTTP/2 to talk to the proxy, which is not something we
support (yet?). Also it's debatable whether or not that setting should
apply to HTTP/2 proxies.

Negotiate: fix for HTTP POST with Negotiate
* Adjusted unit tests 2056, 2057
* do not generally close connections with CURLAUTH_NEGOTIATE after every request
* moved negotiatedata from UrlState to connectdata
* Added stream rewind logic for CURLAUTH_NEGOTIATE
* introduced negotiatedata::GSS_AUTHDONE and negotiatedata::GSS_AUTHSUCC
* Consider authproblem state for CURLAUTH_NEGOTIATE
* Consider reuse_forbid for CURLAUTH_NEGOTIATE
* moved and adjusted negotiate authentication state handling from
  output_auth_headers into Curl_output_negotiate
* Curl_output_negotiate: ensure auth done is always set
* Curl_output_negotiate: Set auth done also if result code is
  GSS_S_CONTINUE_NEEDED/SEC_I_CONTINUE_NEEDED as this result code may
  also indicate the last challenge request (only works with disabled
  Expect: 100-continue and CURLOPT_KEEP_SENDING_ON_ERROR -> 1)
* Consider "Persistent-Auth" header, detect if not present;
  Reset/Cleanup negotiate after authentication if no persistent
  authentication
* apply changes introduced with #2546 for negotiate rewind logic

http: send payload when (proxy) authentication is done
The check that prevents payload from sending in case of authentication
doesn't check properly if the authentication is done or not.

They're cases where the proxy respond "200 OK" before sending
authentication challenge. This change takes care of that.

http: set state.infilesize when sending formposts
Without it set, we would unwillingly triger the "HTTP error before end
of send, stop sending" condition even if the entire POST body had been
sent (since it wouldn't know the expected size) which would
unnecessarily log that message and close the connection when it didn't
have to.

memory. For a rather feature-complete build on x86_64 Linux, gcc 8.1.2

Removed an unused struct field.

No functionality changes.

http: make adding a blank header thread-safe
Previously the function would edit the provided header in-place when a
semicolon is used to signify an empty header. This made it impossible to
use the same set of custom headers in multiple threads simultaneously.

This approach now makes a local copy when it needs to edit the string.

http: added options for allowing HTTP/0.9 responses
Added CURLOPT_HTTP09_ALLOWED and --http0.9 for this purpose.

For now, both the tool and library allow HTTP/0.9 by default.
docs/DEPRECATE.md lays out the plan for when to reverse that default: 6
months after the 7.64.0 release. The options are added already now so
that applications/scripts can start using them already now.

http: Implement trailing headers for chunked transfers
This adds the CURLOPT_TRAILERDATA and CURLOPT_TRAILERFUNCTION
options that allow a callback based approach to sending trailing headers
with chunked transfers.

The test server (sws) was updated to take into account the detection of the
end of transfer in the case of trailing headers presence.

Test 1591 checks that trailing headers can be sent using libcurl.

NTLM: force the connection to HTTP/1.1
Since v7.62.0, cURL tries to use HTTP/2 whenever the server announces
the capability. However, NTLM authentication only works with HTTP/1.1,
and will likely remain in that boat (for details, see
https://docs.microsoft.com/en-us/iis/get-started/whats-new-in-iis-10/http2-on-iis#when-is-http2-not-supported).

When we just found out that we want to use NTLM, and when the current
connection runs in HTTP/2 mode, let's force the connection to be closed
and to be re-opened using HTTP/1.1.

Fixes https://github.com/curl/curl/issues/3341.

auth: only ever pick CURLAUTH_BEARER if we *have* a Bearer token
The Bearer authentication was added to cURL 7.61.0, but there is a
problem: if CURLAUTH_ANY is selected, and the server supports multiple
authentication methods including the Bearer method, we strongly prefer
that latter method (only CURLAUTH_NEGOTIATE beats it), and if the Bearer
authentication fails, we will never even try to attempt any other
method.

This is particularly unfortunate when we already know that we do not
have any Bearer token to work with.

Such a scenario happens e.g. when using Git to push to Visual Studio
Team Services (which supports Basic and Bearer authentication among
other methods) and specifying the Personal Access Token directly in the
URL (this aproach is frequently taken by automated builds).

Let's make sure that we have a Bearer token to work with before we
select the Bearer authentication among the available authentication
methods.
