Rob Allen 56996dabe6 BUG/MINOR: mworker/ssl: close OpenSSL FDs on reload 
From OpenSSL 1.1.1, the default behaviour is to maintain open FDs to any
random devices that get used by the random number library. As a result,
those FDs leak when the master re-execs on reload; since those FDs are
not marked FD_CLOEXEC or O_CLOEXEC, they also get inherited by children.
Eventually both master and children run out of FDs.

OpenSSL 1.1.1 introduces a new function to control whether the random
devices are kept open. When clearing the keep-open flag, it also closes
any currently open FDs, so it can be used to clean-up open FDs too.
Therefore, a call to this function is made in mworker_reload prior to
re-exec.

The call is guarded by whether SSL is in use, because it will cause
initialisation of the OpenSSL random number library if that has not
already been done.

This should be backported to 1.9 and 1.8.

ease of use.

Please refer to the following files depending on what you're looking for :

  - INSTALL for instructions on how to build and install HAProxy
  - LICENSE for the project's license
  - CONTRIBUTING for the process to follow to submit contributions

The more detailed documentation is located into the doc/ directory :

  - doc/intro.txt for a quick introduction on HAProxy
  - doc/configuration.txt for the configuration's reference manual
  - doc/lua.txt for the Lua's reference manual
  - doc/SPOE.txt for how to use the SPOE engine
  - doc/network-namespaces.txt for how to use network namespaces under Linux
  - doc/management.txt for the management guide
  - doc/regression-testing.txt for how to use the regression testing suite
  - doc/peers.txt for the peers protocol reference
  - doc/coding-style.txt for how to adopt HAProxy's coding style
  - doc/internals for developer-specific documentation (not all up to date)
