librelp: upgrade 1.10.0 -> 1.11.0

Changelog:
===========
- code cleanup
  During the initial librelp implementation it was thought about an
  auto-retry feature (whatever that means). Variable bAutoRetry was
  created to control that behaviour. It's default was 0 (inactive).
  Some code has been written to evaluate that variable and act
  accordingly. However, no setter method for this variable was
  created and it was also nowhere changed from the default value
  of zero. As such, the code activated by it was never used.
  This patch now removes both the variable and the few code lines
  accessing it. This will have no effect, as the code was never
  used.
- testbench: Fix commands in some openssl tests
  Those commands were not correctly handeled on AIX, now they are.
- AIX: Changed ERRNO handling after connect in tcp.c
- AIX: Add handling for other ERRNO codes in tcp.c
- bugfix/TCP: relpTcpGetRtryDirection onyl needs to check direction if SSL is active.
- AIX: in relpTcpRcv we need to set RETRY_recv if errno is 0
  On AIX 10.x, when a recv call fails with len -1 and errno 0
  we can still go into relpTCP_RETRY_recv mode. Testbench on
  rsyslog side appears to be finally working with this fix.
  On AIX 10.x, same problem as above appear to happen with
  connect() as well not setting errno to EINPROGRESS on failure.
  rsyslog ptcp driver does not check errno value at all, which is
  why we did not have this problem on AIX with rsyslog.
  Reduce test message count in receiver-abort.sh to 50000,
  because otherwise the test can timeout on very slow machines.
- openssl: fix openssl exit code avoid double free of ctx
  When more than one librelp instance are used in the same process,
  and the relpTcpExitTLS call was called a second time, the process
  could freeze due a double free (See SSL_CTX_free call).
  Thanks to David GOUARIN <david.gouarin@thalesgroup.com> for the
  discovery and initial fix.
  Also added an openssl instance counter to avoid freeing the SSL library
  which could be still in use by another librelp instance
  in the same process.
- librelp hardening: Fix multiple minor issues causing debugging trouble
  - avoid invalid dbgprint calls
  - avoid double free in relpTcpDestruct (if called twice).
  - add debug output into relpTcpRcv
- OpenSSL: fix depreacted API issues for OpenSSL 3.x
  - OpenSSL error strings are loaded automatically now
  - Adapted Debug Callback for 3.x
- bugfix: compatiblity problem with openssl 1.1
  There were undefined reference to CRYPTO_set_id_callback if system
  use openssl 1.1, which lead to load and/or other erros.
- bugfix: Forward return code from relpEngineSetTLSLib to relpEngineSetTLSLibName
  Previous situation: In case librelp is compiled without openssl
  support but openssl is requested from the user side, then librelp
  silently switches to the default tls driver(gnutls).
- bugfix: make relpEngineSetTLSLib debug safe
  In case pThis == NULL condition is true at line
- bugfix: warnings reported by coverity scan
- testbench: Added compatiblity to run on AIX
  - removed long options from receive send utilities (Not supported on AIX).
  - added checks for existing commands in some tests.
  - added msleep utility from rsyslog (sleep, timeout etc. not supported on AIX).
  - github workflow: Disabled some unrelated tests from rsyslog testbench
- gnutls drvr bugfix: library called exit() under some circumstances
  When relpTcpRcv ran into an error, it could call exit() and thus
  terminate the calling process.
