  Log Message:
  Update socat to 1.7.3.0. From Ben Gergely in PR pkg/49996.

  ####################### V 1.7.3.0:

  security:
          (CVE Id pending)
          Fixed problems with signal handling caused by use of not async signal
          safe functions in signal handlers that could freeze socat, allowing
          denial of service attacks.
          Many changes in signal handling and the diagnostic messages system were
          applied to make the code async signal safe but still provide detailled
          logging from signal handlers:
          Coded function vsnprintf_r() as async signal safe incomplete substitute
          of libc vsnprintf()
          Coded function snprinterr() to replace %m in strings with a system error
          message
          Instead of gettimeofday() use clock_gettime() when available
          Pass Diagnostic messages from signal handler per unix socket to the main
          program flow
          Use sigaction() instead of signal() for better control
          Turn off nested signal handler invocations
          Thanks to Peter Lobsinger for reporting and explaining this issue.

          Red Hat issue 1019975: add TLS host name checks
          OpenSSL client checks if the server certificates names in
          extensions/subjectAltName/DNS or in subject/commonName match the name
          used to connect or the value of the openssl-commonname option.
          Test: OPENSSL_CN_CLIENT_SECURITY

          OpenSSL server checks if the client certificates names in
          extensions/subjectAltNames/DNS or subject/commonName match the value of
          the openssl-commonname option when it is used.
          Test: OPENSSL_CN_SERVER_SECURITY

          Red Hat issue 1019964: socat now uses the system certificate store with
          OPENSSL when neither options cafile nor capath are used

          Red Hat issue 1019972: needs to specify OpenSSL cipher suites
          Default cipherlist is now "HIGH:-NULL:-PSK:-aNULL" instead of empty to
          prevent downgrade attacks

  new features:
          OpenSSL addresses set couple of environment variables from values in
          peer certificate, e.g.:
          SOCAT_OPENSSL_X509_SUBJECT, SOCAT_OPENSSL_X509_ISSUER,
          SOCAT_OPENSSL_X509_COMMONNAME,
          SOCAT_OPENSSL_X509V3_SUBJECTALTNAME_DNS
          Tests: ENV_OPENSSL_{CLIENT,SERVER}_X509_*

          Added support for methods TLSv1, TLSv1.1, TLSv1.2, and DTLS1
          Tests: OPENSSL_METHOD_*

          Enabled OpenSSL server side use of ECDHE ciphers. Feature suggested
          by Andrey Arapov.

          Added a new option termios-rawer for ptys.
          Thanks to Christian Vogelgsang for pointing me to this requirement

  corrections:
          Bind with ABSTRACT commands used non-abstract namespace (Linux).
          Test: ABSTRACT_BIND
          Thanks to Denis Shatov for reporting this bug.

          Fixed return value of nestlex()

          Option ignoreeof on the right address hung.
          Test: IGNOREEOF_REV
          Thanks to Franz Fasching for reporting this bug.

          Address SYSTEM, when terminating, shut down its parent addresses,
          e.g. an SSL connection which the parent assumed to still be active.
          Test: SYSTEM_SHUTDOWN

          Passive (listening or receiving) addresses with empty port field bound
          to a random port instead of terminating with error.
          Test: TCP4_NOPORT

          configure with some combination of disable options produced config
          files that failed to compile due to missing IPPROTO_TCP.
          Thanks to Thierry Fournier for report and patch.

          fixed a few minor bugs with OpenSSL in configure and with messages

          Socat did not work in FIPS mode because 1024 instead of 512 bit DH prime
          is required. Thanks to Zhigang Wang for reporting and sending a patch.

          Christophe Leroy provided a patch that fixes memory leaks reported by
          valgrind

          Help for filan -L was bad, is now corrected to:
          "follow symbolic links instead of showing their properties"

          Address options fdin and fdout were silently ignored when not applicable
          due to -u or -U option. Now these combinations are caught as errors.
          Test: FDOUT_ERROR
          Issue reported by Hendrik.

          Added option termios-cfmakeraw that calls cfmakeraw() and is preferred
          over option raw which is now obsolote. On SysV systems this call is
          simulated by appropriate setting.
          Thanks to Youfu Zhang for reporting issue with option raw.

  porting:
          Socat included <sys/poll.h> instead of POSIX <poll.h>
          Thanks to John Spencer for reporting this issue.

          Version 1.7.2.4 changed the check for gcc in configure.ac; this
          broke cross compiling. The particular check gets reverted.
          Thanks to Ross Burton and Danomi Manchego for reporting this issue.

          Debian Bug#764251: Set the build timestamp to a deterministic time:
          support external BUILD_DATE env var to allow to build reproducable
          binaries

          Joachim Fenkes provided an new adapted spec file.

          Type bool and macros Min and Max are defined by socat which led to
          compile errors when they were already provided by build framework.
          Thanks to Liyu Liu for providing a patch.

          David Arnstein contributed a patch for NetBSD 5.1 including stdbool.h
          support and appropriate files in Config/

          Lauri Tirkkonen contributed a patch regarding netinet/if_ether.h
          on Illumos

          Changes for Openindiana: define _XPG4_2, __EXTENSIONS__,
          _POSIX_PTHREAD_SEMANTICS; and minor changes

          Red Hat issue 1182005: socat 1.7.2.4 build failure missing
          linux/errqueue.h
          Socat failed to compile on on PPC due to new requirements for
          including <linux/errqueue.h> and a weakness in the conditional code.
          Thanks to Michel Normand for reporting this issue.

  doc:
          In the man page the PTY example was badly formatted. Thanks to
          J.F.Sebastian for sending a patch.

          Added missing CVE ids to security issues in CHANGES

  testing:
          Do not distribute testcert.conf with socat source but generate it
          (and new testcert6.conf) during test.sh run.

  ####################### V 1.7.2.4:

  corrections:
          LISTEN based addresses applied some address options, e.g. so-keepalive,
          to the listening file descriptor instead of the connected file
          descriptor
          Thanks to Ulises Alonso for reporting this bug

          make failed after configure with non gcc compiler due to missing
          include. Thanks to Horacio Mijail for reporting this problem

          --disable-genericsocket in the help text. Thanks to Ben Gardiner for
          reporting and patching this bug

          In xioshutdown() a wrong branch was chosen after RECVFROM type
  addresses.
          Probably no impact.
          Thanks to David Binderman for reproting this issue.

          procan could not cleanly format ulimit values longer than 16 decimal
          digits. Thanks to Frank Dana for providing a patch that increases field
          width to 24 digits.

          OPENSSL-CONNECT with bind option failed on some systems,
  eg.FreeBSD, with
          "Invalid argument"
          Thanks to Emile den Tex for reporting this bug.

          Changed some variable definitions to make gcc -O2 aliasing checker happy
          Thanks to Ilya Gordeev for reporting these warnings

          On big endian platforms with type long >32bit the range option applied a

          Red Hat issue 1021967: formatting error in manual page

          UNIX-LISTEN with fork option did not remove the socket file system entry
          when exiting. Other file system based passive address types had similar
          issues or failed to apply options umask, user e.a.
          Thanks to Lorenzo Monti for pointing me to this issue

  porting:
          Red Hat issue 1020203: configure checks fail with some compilers.
          Use case: clang

          Performed changes for Fedora release 19

          Adapted, improved test.sh script
