- vtls: add MesaLink to curl_sslbackend enum
  
  MesaLink support was added in commit 57348eb97d1b8fc3742e02c but the
  backend was never added to the curl_sslbackend enum in curl/curl.h.
  This adds the new backend to the enum and updates the relevant docs.

  x509asn1: Fix SAN IP address verification
  
  For IP addresses in the subject alternative name field, the length
  of the IP address (and hence the number of bytes to perform a
  memcmp on) is incorrectly calculated to be zero. The code previously
  subtracted q from name.end. where in a successful case q = name.end
  and therefore addrlen equalled 0. The change modifies the code to
  subtract name.beg from name.end to calculate the length correctly.
  
  The issue only affects libcurl with GSKit SSL, not other SSL backends.
  The issue is not a security issue as IP verification would always fail.

  CMake: Improve config installation
  
  Use 'GNUInstallDirs' standard module to set destinations of installed
  files.
  
  Use uppercase "CURL" names instead of lowercase "curl" to match standard
  'FindCURL.cmake' CMake module:
  * https://cmake.org/cmake/help/latest/module/FindCURL.html
  
  Meaning:
  * Install 'CURLConfig.cmake' instead of 'curl-config.cmake'
  * User should call 'find_package(CURL)' instead of 'find_package(curl)'
  
  Use 'configure_package_config_file' function to generate
  'CURLConfig.cmake' file. This will make 'curl-config.cmake.in' template
  file smaller and handle components better.  E.g.  current configuration
  report no error if user specified unknown components (note: new
  configuration expects no components, report error if user will try to
  specify any).

- vtls: fix ssl version "or later" behavior change for many backends
  
  - Treat CURL_SSLVERSION_MAX_NONE the same as
    CURL_SSLVERSION_MAX_DEFAULT. Prior to this change NONE would mean use
    the minimum version also as the maximum.
  
  This is a follow-up to 6015cef which changed the behavior of setting
  the SSL version so that the requested version would only be the minimum
  and not the maximum. It appears it was (mostly) implemented in OpenSSL
  but not other backends. In other words CURL_SSLVERSION_TLSv1_0 used to
  mean use just TLS v1.0 and now it means use TLS v1.0 *or later*.
  
  - Fix CURL_SSLVERSION_MAX_DEFAULT for OpenSSL.
  
  Prior to this change CURL_SSLVERSION_MAX_DEFAULT with OpenSSL was
  erroneously treated as always TLS 1.3, and would cause an error if
  OpenSSL was built without TLS 1.3 support.

- test324: fix after 3f3b26d6feb0667714902e836af608094235fca2
  
  The expected error code is now 60. 51 is dead.

Daniel Stenberg (8 Sep 2018)
- curl_url_set.3: correct description

- curl_url-docs: fix AVAILABILITY as Added in curl 7.62.0

- URL-API
  
  See header file and man pages for API. All documented API details work
  and are tested in the 1560 test case.
  
  Closes #2842

- curl_easy_upkeep: removed 'conn' from the name
  
  ... including the associated option.
  
  Fixes #2951
  Closes #2952

- [Max Dymond brought this change]

  upkeep: add a connection upkeep API: curl_easy_conn_upkeep()
  
  Add functionality so that protocols can do custom keepalive on their
  connections, when an external API function is called.
  
  Add docs for the new options in 7.62.0
  
  Closes #1641

- [Philipp Waehnert brought this change]

  configure: add option to disable automatic OpenSSL config loading
  
  Sometimes it may be considered a security risk to load an external
  OpenSSL configuration automatically inside curl_global_init(). The
  configuration option --disable-ssl-auto-load-config disables this
  automatism. The Windows build scripts winbuild/Makefile.vs provide a
  corresponding option ENABLE_SSL_AUTO_LOAD_CONFIG accepting a boolean
  value.
  
  Setting neither of these options corresponds to the previous behavior
  loading the external OpenSSL configuration automatically.
  
  Fixes #2724
  Closes #2791

- doh: minor edits to please Coverity
  
  The gcc typecheck macros and coverity combined made it warn on the 2nd
  argument for ERROR_CHECK_SETOPT(). Here's minor rearrange to please it.
  
  Coverity CID 1439115 and CID 1439114.

- schannel: avoid switch-cases that go to default anyway
  
  SEC_E_APPLICATION_PROTOCOL_MISMATCH isn't defined in some versions of
  mingw and would require an ifdef otherwise.

  Bug: https://curl.haxx.se/mail/lib-2018-09/0020.html
  Closes #2950

- [Nicklas Avén brought this change]

  imap: change from "FETCH" to "UID FETCH"
  
  ... and add "MAILINDEX".
  
  As described in #2789, this is a suggested solution.  Changing UID=xx to
  actually get mail with UID xx and add "MAILINDEX" to get a mail with a
  special index in the mail box (old behavior).  So MAILINDEX=1 gives the
  first non deleted mail in the mail box.
  
  Fixes #2789
  Closes #2815

- CURLOPT_UPLOAD_BUFFERSIZE: set upload buffer size
  
  This is step 3 of #2888.
  
  Fixes #2888
  Closes #2896

- travis: add the DOH tests to the torture testing

  ssl: deprecate CURLE_SSL_CACERT in favour of a unified error code
  
  Long live CURLE_PEER_FAILED_VERIFICATION

- [Han Han brought this change]

  x509asn1: return CURLE_PEER_FAILED_VERIFICATION on failure to parse cert
  
  CURLE_PEER_FAILED_VERIFICATION makes more sense because Curl_parseX509
  does not allocate memory internally as its first argument is a pointer
  to the certificate structure. The same error code is also returned by
  Curl_verifyhost when its call to Curl_parseX509 fails so the change
  makes error handling more consistent.

- [Han Han brought this change]

  openssl: return CURLE_PEER_FAILED_VERIFICATION on failure to parse issuer
  
  Failure to extract the issuer name from the server certificate should
  return a more specific error code like on other TLS backends.

- [Han Han brought this change]

  schannel: unified error code handling
  
  Closes #2901

  darwinssl: more specific and unified error codes

  Closes #2942

- url: default to CURL_HTTP_VERSION_2TLS if built h2-enabled
  
  Closes #2709

- multiplex: enable by default
  
  Starting 7.62.0, multiplexing is enabled by default in multi handles.

- [Jim Fuller brought this change]

  tests: add unit tests for url.c
  
  Approved-by: Daniel Gustafsson
  Closes #2937

- test1452: mark as flaky
  
  makes it not run in the CI builds
  
  Closes #2941

- pipelining: deprecated
  
  Transparently. The related curl_multi_setopt() options all still returns
  OK when pipelining is selected.
  
  To re-enable the support, the single line change in lib/multi.c needs to
  be reverted.
  
  See docs/DEPRECATE.md
  
  Closes #2705
