- version update to 2.4.43
  * ) mod_ssl: Fix memory leak of OCSP stapling response. [Yann Ylavic]
  * ) mod_proxy_http: Fix the forwarding of requests with content body when a
    balancer member is unavailable; the retry on the next member was issued
    with an empty body (regression introduced in 2.4.41). PR63891.
    [Yann Ylavic]
  * ) mod_http2: Fixes issue where mod_unique_id would generate non-unique request
    identifier under load, see <https://github.com/icing/mod_h2/issues/195>.
    [Michael Kaufmann, Stefan Eissing]
  * ) mod_proxy_hcheck: Allow healthcheck expressions to use %{Content-Type}.
    PR64140. [Renier Velazco <renier.velazco upr.edu>]
  * ) mod_authz_groupfile: Drop AH01666 from loglevel "error" to "info".
    PR64172.
  * ) mod_usertrack: Add CookieSameSite, CookieHTTPOnly, and CookieSecure
    to allow customization of the usertrack cookie. PR64077.
    [Prashant Keshvani <prashant2400 gmail.com>, Eric Covener]
  * ) mod_proxy_ajp: Add "secret" parameter to proxy workers to implement legacy
    AJP13 authentication.  PR 53098. [Dmitry A. Bakshaev <dab1818 gmail com>]
  * ) mpm_event: avoid possible KeepAliveTimeout off by -100 ms.
    [Eric Covener, Yann Ylavic]
  * ) Add a config layout for OpenWRT. [Graham Leggett]
  * ) Add support for cross compiling to apxs. If apxs is being executed from
    somewhere other than its target location, add that prefix to includes and
    library directories. Without this, apxs would fail to find config_vars.mk
    and exit. [Graham Leggett]
  * ) mod_ssl: Disable client verification on ACME ALPN challenges. Fixes github
    issue mod_md#172 (https://github.com/icing/mod_md/issues/172).
    [Michael Kaufmann <mail michael-kaufmann.ch>, Stefan Eissing]
  * ) mod_ssl: use OPENSSL_init_ssl() to initialise OpenSSL on versions 1.1+.
    [Graham Leggett]
  * ) mod_ssl: Support use of private keys and certificates from an
    OpenSSL ENGINE via PKCS#11 URIs in SSLCertificateFile/KeyFile.
    [Anderson Sasaki <ansasaki redhat.com>, Joe Orton]
  * ) mod_md:
  - Prefer MDContactEmail directive to ServerAdmin for registration. New directive
    thanks to Timothe Litt (@tlhackque).
  - protocol check for pre-configured "tls-alpn-01" challenge has been improved. It will now
    check all matching virtual hosts for protocol support. Thanks to @mkauf.
  - Corrected a check when OCSP stapling was configured for hosts
    where the responsible MDomain is not clear, by Michal Karm Babacek (@Karm).
  - Softening the restrictions where mod_md configuration directives may appear. This should
    allow for use in <If> and <Macro> sections. If all possible variations lead to the configuration
    you wanted in the first place, is another matter.
    [Michael Kaufmann <mail michael-kaufmann.ch>, Timothe Litt (@tlhackque),
    Michal Karm Babacek (@Karm), Stefan Eissing (@icing)]
  * ) test: Added continuous testing with Travis CI.
    This tests various scenarios on Ubuntu with the full test suite.
    Architectures tested: amd64, s390x, ppc64le, arm64
    The tests pass successfully.
    [Luca Toscano, Joe Orton, Mike Rumph, and others]
  * ) core: Be stricter in parsing of Transfer-Encoding headers.
    [ZeddYu <zeddyu.lu gmail.com>, Eric Covener]
  * ) mod_ssl: negotiate the TLS protocol version per name based vhost
    configuration, when linked with OpenSSL-1.1.1 or later. The base vhost's
    SSLProtocol (from the first vhost declared on the IP:port) is now only
    relevant if no SSLProtocol is declared for the vhost or globally,
    otherwise the vhost or global value apply.  [Yann Ylavic]
  * ) mod_cgi, mod_cgid: Fix a memory leak in some error cases with large script
    output.  PR 64096.  [Joe Orton]
  * ) config: Speed up graceful restarts by using pre-hashed command table. PR 64066.
    [Giovanni Bechis <giovanni paclan.it>, Jim Jagielski]
  * ) mod_systemd: New module providing integration with systemd.  [Jan Kaluza]
  * ) mod_lua: Add r:headers_in_table, r:headers_out_table, r:err_headers_out_table,
    r:notes_table, r:subprocess_env_table as read-only native table alternatives
    that can be iterated over. [Eric Covener]
  * ) mod_http2: Fixed rare cases where a h2 worker could deadlock the main connection.
    [Yann Ylavic, Stefan Eissing]
  * ) mod_lua: Accept nil assignments to the exposed tables (r.subprocess_env,
    r.headers_out, etc) to remove the key from the table. PR63971.
    [Eric Covener]
  * ) mod_http2: Fixed interaction with mod_reqtimeout. A loaded mod_http2 was disabling the
    ssl handshake timeouts. Also, fixed a mistake of the last version that made `H2Direct`
    always `on`, regardless of configuration. Found and reported by
    <Armin.Abfalterer@united-security-providers.ch> and
    <Marcial.Rion@united-security-providers.ch>. [Stefan Eissing]
  * ) mod_http2: Multiple field length violations in the same request no longer cause
    several log entries to be written. [@mkauf]
  * ) mod_ssl: OCSP does not apply to proxy mode.  PR 63679.
    [Lubos Uhliarik <luhliari redhat.com>, Yann Ylavic]
  * ) mod_proxy_html, mod_xml2enc: Fix build issues with macOS due to r1864469
    [Jim Jagielski]
  * ) mod_authn_socache: Increase the maximum length of strings that can be cached by
    the module from 100 to 256.  PR 62149 [<thorsten.meinl knime.com>]
  * ) mod_proxy: Fix crash by resolving pool concurrency problems. PR 63503
    [Ruediger Pluem, Eric Covener]
  * ) core: On Windows, fix a start-up crash if <IfFile ...> is used with a path that is not
    valid (For example, testing for a file on a flash drive that is not mounted)
    [Christophe Jaillet]
  * ) mod_deflate, mod_brotli: honor "Accept-Encoding: foo;q=0" as per RFC 7231; which
    means 'foo' is "not acceptable".  PR 58158 [Chistophe Jaillet]
  * ) mod_md v2.2.3:
  - Configuring MDCAChallenges replaces any previous existing challenge configuration. It
    had been additive before which was not the intended behaviour. [@mkauf]
  - Fixing order of ACME challenges used when nothing else configured. Code now behaves as
    documented for `MDCAChallenges`. Fixes #156. Thanks again to @mkauf for finding this.
  - Fixing a potential, low memory null pointer dereference [thanks to @uhliarik].
  - Fixing an incompatibility with a change in libcurl v7.66.0 that added unwanted
    "transfer-encoding" to POST requests. This failed in directy communication with
    Let's Encrypt boulder server. Thanks to @mkauf for finding and fixing. [Stefan Eissing]
  * ) mod_md: Adding the several new features.
    The module offers an implementation of OCSP Stapling that can replace fully or
    for a limited set of domains the existing one from mod_ssl. OCSP handling
    is part of mod_md's monitoring and message notifications. If can be used
    for sites that do not have ACME certificates.
    The url for a CTLog Monitor can be configured. It is used in the server-status
    to link to the external status page of a certicate.
    The MDMessageCmd is called with argument "installed" when a new certificate
    has been activated on server restart/reload. This allows for processing of
    the new certificate, for example to applications that require it in different
    locations or formats.

  * ) mod_proxy_balancer: Fix case-sensitive referer check related to CSRF/XSS
    protection. PR 63688. [Armin Abfalterer <a.abfalterer gmail.com>]

- build mod_proxy_http2 extension

- fix build for older distributions

- define DEFAULT_LISTENBACKLOG=APR_INT32_MAX. We want apache
  to honour net.core.somaxconn sysctl as the mandatory limit.
  the old value of 511 was never used as until v5.4-rc6 it was
  clamped to 128, in current kernels the default limit is 4096.
  Cannot use the apr_socket_listen(.., -1) idiom because the function
  expects a positive integer argument.
