configure: detect getsockname and getpeername on windows too
Made detection macros for these two functions in the same style as other
functions possibly in winsock in the hope this will work better to
detect these functions when cross-compiling for Windows.
When compiling without getpeername() or getsockname(), the sockfd
paramter to Curl_udpateconninfo() became unused after commit e91e481612
added ifdef guards.
Closes #3910

the FTP featureflag in the UserDefined struct, but vtls callsites were
still using it unprotected.

version: make ssl_version buffer match for multi_ssl
When running a multi TLS backend build the version string needs more
buffer space. Make the internal ssl_buffer stack buffer match the one
in Curl_multissl_version() to allow for the longer string. For single
TLS backend builds there is no use in extended to buffer. This is a
fallout from #3863 which fixes up the multi_ssl string generation to
avoid a buffer overflow when the buffer is too small.

http_ntlm_wb: Handle auth for only a single request
Currently when the server responds with 401 on NTLM authenticated
connection (re-used) we consider it to have failed. However this is
legitimate and may happen when for example IIS is set configured to
'authPersistSingleRequest' or when the request goes thru a proxy (with
'via' header).
Implemented by imploying an additional state once a connection is
re-used to indicate that if we receive 401 we need to restart
authentication.

cleanup: remove FIXME and TODO comments
They serve very little purpose and mostly just add noise. Most of them
have been around for a very long time. I read them all before removing
or rephrasing them.

url: Remove duplicate clean up of the winbind variables in conn_shutdown()
Given that Curl_disconnect() calls Curl_http_auth_cleanup_ntlm() prior
to calling conn_shutdown() and it in turn performs this, there is no
need to perform the same action in conn_shutdown().
In Curl_multissl_version() it was possible to overflow the passed in
buffer if the generated version string exceeded the size of the buffer.
Fix by inverting the logic, and also make sure to not exceed the local
buffer during the string generation.

- No longer show verbose output for the conncache closure handle.
The offending commit was added so that the conncache closure handle
would inherit verbose mode from the user's easy handle. (Note there is
no way for the user to set options for the closure handle which is why
that was necessary.) Other debug settings such as the debug function
were not also inherited since we determined that could lead to crashes
if the user's per-handle private data was used on an unexpected handle.
The reporter here says he has a debug function to capture the verbose
output, and does not expect or want any output to stderr; however
because the conncache closure handle does not inherit the debug function
the verbose output for that handle does go to stderr.
There are other plausible scenarios as well such as the user redirects
stderr on their handle, which is also not inherited since it could lead
to crashes when used on an unexpected handle.
Short of allowing the user to set options for the conncache closure
handle I don't think there's much we can safely do except no longer
inherit the verbose setting.

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.
OpenSSL: Report -fips in version if OpenSSL is built with FIPS
Older versions of OpenSSL report FIPS availabilty via an OPENSSL_FIPS
define. It uses this define to determine whether to publish -fips at
the end of the version displayed. Applications that utilize the version
reported by OpenSSL will see a mismatch if they compare it to what curl
reports, as curl is not modifying the version in the same way. This
change simply adds a check to see if OPENSSL_FIPS is defined, and will
alter the reported version to match what OpenSSL itself provides. This
only appears to be applicable in versions of OpenSSL <1.1.1

nss: allow fifos and character devices for certificates.
Currently you can do things like --cert <(cat ./cert.crt) with (at least) the
openssl backend, but that doesn't work for nss because is_file rejects fifos.
I don't actually know if this is sufficient, nss might do things internally
(like seeking back) that make this not work, so actual testing is needed.
