Subject: [PATCH] setopt: enable CURLOPT_SSH_KNOWNHOSTS and
CURLOPT_SSH_KEYFUNCTION for libssh
CURLOPT_SSH_KNOWNHOSTS and CURLOPT_SSH_KEYFUNCTION are supported for
libssh as well. So accepting these options only when compiling with
libssh2 is wrong here.
Fixes #3493
Closes #3494

Subject: [PATCH] Upon HTTP_1_1_REQUIRED, retry the request with HTTP/1.1
This is a companion patch to cbea2fd2c (NTLM: force the connection to
HTTP/1.1, 2018-12-06): with NTLM, we can switch to HTTP/1.1
preemptively. However, with other (Negotiate) authentication it is not
clear to this developer whether there is a way to make it work with
HTTP/2, so let's try HTTP/2 first and fall back in case we encounter the
error HTTP_1_1_REQUIRED.
Note: we will still keep the NTLM workaround, as it avoids an extra
round trip.
Daniel Stenberg helped a lot with this patch, in particular by
suggesting to introduce the Curl_h2_http_1_1_error() function.
Closes #3349

Subject: [PATCH 1/2] strcase: add Curl_timestrcmp
This is a strcmp() alternative function for comparing "secrets",
designed to take the same time no matter the content to not leak
match/non-match info to observers based on how fast it is.
The time this function takes is only a function of the shortest input
string.
Reported-by: Trail of Bits
Closes #9658

Subject: [PATCH] ssh-libssh: do not specify O_APPEND when not in append mode
Specifying O_APPEND in conjunction with O_TRUNC and O_CREAT does not
make much sense. And this combination of flags is not accepted by all
SFTP servers (at least not Apache SSHD).

Subject: [PATCH] libssh: when keyboard-interactive auth fails, try password
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
The state machine had a mistake in that it would not carry on to that
next step.
This also adds a verbose output what methods that are available from the
server and renames the macros that change to the next auth methods to
try.
Reported-by: 左潇峰
Fixes #11196
Closes #11197

Subject: [PATCH] lib: unify the upload/method handling
By making sure we set state.upload based on the set.method value and not
independently as set.upload, we reduce confusion and mixup risks, both
internally and externally.

Subject: [PATCH] cookie: remove unnecessary struct fields
Plus: reduce the hash table size from 256 to 63. It seems unlikely to
make much of a speed difference for most use cases but saves 1.5KB of
data per instance.
