9.2.4: PCNTL functionality verification

• Merged PR #11: Raise exceptions when pcntl extension is not loaded or
  disabled. Previously, this would fail more or less silently later on!
  (@thekid)

9.2.3: Logging compatiblity

• Made compatible with xp-framework/logging version 9.0.0 - @thekid

9.2.2: Inet4Address fix

• Fixed Inet4Address not implementing lang.Value - @thekid

9.2.1: Housekeeping fixes

• Fixed server implementation to run housekeeping after a given timeout
  period, which defaults to 60 seconds.
  (@thekid)
• Fixed issue #10: Select(60, 0) failed - @thekid
• Fixed issue #9: ServerSocket binds tcp://::1:8080 by default - @thekid

9.2.0: Servers & built-in streams

• Merged PR #8: Make ServerSocket use built-in streams. This removes the
  hard dependency on the sockets extension for the peer.server API.
  If it's available, the code will continue to use it as default until
  the next major release of this library. Otherwise, the built-in streams
  and PHP's stream_socket_server() will be used.

9.1.2: Localhost certificate validation fix

• Fixed certificate validation problem when connecting to localhost
  via SSL. Issue #2 caused this problem by forcing sockets using localhost
  as hostname to connect to 127.0.0.1
  (@thekid)

9.1.1: Dependencies fix

• Fixed issue #6: Missing dependency on xp-framework/logging - @thekid

9.1.0: SOMAXCONN

• Merged PR #5: Pass SOMAXCONN to listen() call - @thekid

9.0.0: XP9 Compatibility

• Heads up: Dropped PHP 5.5 support - now requires PHP 5.6 minimum!
  (@thekid)
• Merged PR #3: XP9 Compat. Heads up: peer.Socket, peer.URL, the
  INetAddr implementations in peer.net as well as peer.net.Network now
  implement lang.Value instead of extending lang.Object.

8.0.2: Error message QA

• Trimmed error messages - those under Windows include a traling \r\n.
