Log Message:
p5-IO-Socket-SSL: update to 2.056.

2.056 2018/02/19
- Intercept - fix creation of serial number: base it on binary digest instead of
  treating hex fingerprint as binary. Allow use of own serial numbers again.
- t/io-socket-ip.t - skip test if no IPv6 support on system RT#124464
- update PublicSuffix
2.055 2018/02/15
- use SNI also if hostname was given all-uppercase
- Utils::CERT_create - don't add authority key for issuer since Chrome does
  not like this
- Intercept:
  - change behavior of code based cache to better support synchronizing
    within multiprocess/threaded setups
  - don't use counter for serial number but somehow base it on original
    certificate in order to avoid conflicts with reuse of serial numbers
    after restart
- RT#124431 - better support platforms w/o IPv6
- RT#124306 - spelling fixes in documentation
2.054 2018/01/22
- added missing test certificates to MANIFEST
2.053 2018/01/21
- small behavior fixes
  - if SSL_fingerprint is used and matches don't check for OCSP
  - Utils::CERT_create - small fixes to properly specific purpose, ability to
    use predefined complex purpose but disable some features
- update PublicSuffix
- updates for documentation, especially regarding pitfalls with forking or using
  non-blocking sockets. Spelling fixes.
- test fixes and improvements
  - stability improvements for live tests
  - regenerate certificate in certs/ and make sure they are limited to the
    correct purpose. Checkin program used to generate certificates.
  - adjust tests since certificates have changed and some tests used
    certificates intended for client authentication as server certificates,
    which now no longer works
