MFH: r371716

Update to 0.6.3 to fix CVE-2014-0017.

While here, get rid of a lot of cruft:
- Use an https in MASTER_SITES and stop using a snapshot URL for the
  tarballs.
- Switch to an out-of-source CMake build with USES=cmake:outsource, and get
  rid of all the messing around with CMAKE_SOURCE_PATH and *_WRKSRC.
- Move the LICENSE block to the right place to pet portlint.
- Explicitly set CMAKE_ARGS with some options which we were already
  implicitly assuming to be set.
- Disable examples and tests via CMAKE_ARGS instead of using an ugly sed
  call.
- Do not pass WITH_OPENSSL=ON/OFF to CMake, this has no effect in the build
  system.
- Stop gratuitously including bsd.port.options.mk.
- Remove sed calls and patches related to the libssh_threads. I fixed some
  of the problems a few releases ago upstream, and the things I've removed
  now just look unnecessary.
