  URL: fix ASCII dependency in strcpy_url and strlen_url
  
  Commit 3c630f9b0af097663a64e5c875c580aa9808a92b partially reverted the
  changes from commit dd7521bcc1b7a6fcb53c31f9bd1192fcc884bd56 because of
  the problem that strcpy_url() was modified unilaterally without also
  modifying strlen_url(). As a consequence strcpy_url() was again
  depending on ASCII encoding.
  
  This change fixes strlen_url() and strcpy_url() in parallel to use a
  common host-encoding independent criterion for deciding whether an URL
  character must be %-escaped.

  schannel: add support for CURLOPT_CAINFO
  
  - Move verify_certificate functionality in schannel.c into a new
    file called schannel_verify.c. Additionally, some structure defintions
    from schannel.c have been moved to schannel.h to allow them to be
    used in schannel_verify.c.
  
  - Make verify_certificate functionality for Schannel available on
    all versions of Windows instead of just Windows CE. verify_certificate
    will be invoked on Windows CE or when the user specifies
    CURLOPT_CAINFO and CURLOPT_SSL_VERIFYPEER.
  
  - In verify_certificate, create a custom certificate chain engine that
    exclusively trusts the certificate store backed by the CURLOPT_CAINFO
    file.
  
  - doc updates of --cacert/CAINFO support for schannel
  
  - Use CERT_NAME_SEARCH_ALL_NAMES_FLAG when invoking CertGetNameString
    when available. This implements a TODO in schannel.c to improve
    handling of multiple SANs in a certificate. In particular, all SANs
    will now be searched instead of just the first name.
  
  - Update tool_operate.c to not search for the curl-ca-bundle.crt file
    when using Schannel to maintain backward compatibility. Previously,
    any curl-ca-bundle.crt file found in that search would have been
    ignored by Schannel. But, with CAINFO support, the file found by
    that search would have been used as the certificate store and
    could cause issues for any users that have curl-ca-bundle.crt in
    the search path.
  
  - Update url.c to not set the build time CURL_CA_BUNDLE if the selected
    SSL backend is Schannel. We allow setting CA location for schannel
    only when explicitly specified by the user via CURLOPT_CAINFO /
    --cacert.
  
  - Add new test cases 3000 and 3001. These test cases check that the first
    and last SAN, respectively, matches the connection hostname. New test
    certificates have been added for these cases. For 3000, the certificate
    prefix is Server-localhost-firstSAN and for 3001, the certificate
    prefix is Server-localhost-secondSAN.
  
  - Remove TODO 15.2 (Add support for custom server certificate
    validation), this commit addresses it.
  
  Closes https://github.com/curl/curl/pull/1325

  When a zeroed out allocation is required, use calloc() rather than

  tool_operate: Fix retry on FTP 4xx to ignore other protocols
  
  Only treat response code as FTP response codes in case the
  protocol type is FTP.
  
  This fixes an issue where an HTTP download was treated as FTP
  in case libcurl returned with 33. This happens when the
  download has already finished and the server responses 416:
    HTTP/1.1 416 Requested Range Not Satisfiable
  
  This should not be treated as an FTP error.

  Due to the check in Makefile.vc and MakefileBuild.vc, no make call can

  FTP: allow PASV on IPv6 connections when a proxy is being used
  
  In the situation of a client connecting to an FTP server using an IPv6
  tunnel proxy, the connection info will indicate that the connection is
  IPv6. However, because the server behing the proxy is IPv4, it is
  permissable to attempt PSV mode. In the case of the FTP server being
  IPv4 only, EPSV will always fail, and with the current logic curl will
  be unable to connect to the server, as the IPv6 fwdproxy causes curl to
  think that EPSV is impossible.
  
  Closes #2432

  file: restore old behavior for file:////foo/bar URLs
  
  curl 7.57.0 and up interpret this according to Appendix E.3.2 of RFC
  8089 but then returns an error saying this is unimplemented. This is
  actually a regression in behavior on both Windows and Unix.
  
  Before curl 7.57.0 this URL was treated as a path of "//foo/bar" and
  then passed to the relevant OS API. This means that the behavior of this
  case is actually OS dependent.
  
  The Unix path resolution rules say that the OS must handle swallowing
  the extra "/" and so this path is the same as "/foo/bar"
  
  The Windows path resolution rules say that this is a UNC path and
  automatically handles the SMB access for the program. So curl on Windows
  was already doing Appendix E.3.2 without any special code in curl.
  
  Regression
  
  Closes #2438

  Revert "openssl: Don't add verify locations when verifypeer==0"
  
  This reverts commit dc85437736e1fc90e689bb1f6c51c8f1aa9430eb.
  
  libcurl (with the OpenSSL backend) performs server certificate verification
  even if verifypeer == 0 and the verification result is available using
  CURLINFO_SSL_VERIFYRESULT. The commit that is being reverted caused the
  CURLINFO_SSL_VERIFYRESULT to not have useful information for the
  verifypeer == 0 use case (it would always have
  X509_V_ERR_UNABLE_TO_GET_ISSUER_CERT_LOCALLY).

- multi: improved pending transfers handling => improved performance
  
  When a transfer is requested to get done and it is put in the pending
  queue when limited by number of connections, total or per-host, libcurl
  would previously very aggressively retry *ALL* pending transfers to get
  them transferring. That was very time consuming.
  
  By reducing the aggressiveness in how pending are being retried, we
  waste MUCH less time on putting transfers back into pending again.
  
  Some test cases got a factor 30(!) speed improvement with this change.
  
  Reported-by: Cyril B
  Fixes #2369
  Closes #2383

- pause: when changing pause state, update socket state
  
  Especially unpausing a transfer might have to move the socket back to the

  multi_socket API.

- rate-limit: use three second window to better handle high speeds
  
  Due to very frequent updates of the rate limit "window", it could
  attempt to rate limit within the same milliseconds and that then made
  the calculations wrong, leading to it not behaving correctly on very
  fast transfers.
  
  This new logic updates the rate limit "window" to be no shorter than the
  last three seconds and only updating the timestamps for this when
  switching between the states TOOFAST/PERFORM.
