Return rezny@'s ports to the pool after his commit bit got safekept.

Change cmake default behaviour to outsource.

Ports that build out of source now simply can use "USES=cmake"
instead of "USES=cmake:outsource". Ports that fail to build
out of source now need to specify "USES=cmake:insource".

I tried to only set insource where explictely needed.

Make ninja opt-out in cmake.mk

Using ninja instead of make (1) can lead to significant speed ups while
building.
Therefore switch from having the ninja generator opt-in to having it opt-out.

Previously cmake-ports that wanted to use ninja could set
    CMAKE_NINJA=yes
now, ports that do not work with ninja can set
    cmake:<existing args>,noninja
Note, that needing this should be an exception and most often points to a broken
cmake of the port.

The ports using cmake were modified
* removed USES=gmake, if ninja is used
* removed MAKE_ARGS, if ninja is used
* added the cmake-argument noninja if necessary

devel/xxhash: new port

xxHash is an extremely fast non-cryptographic hash algorithm, running at RAM
speed limits.  It is proposed in two flavors, 32 and 64 bits. It successfully
completes the SMHasher test suite which evaluates collision, dispersion and
randomness qualities of hash functions. Code is highly portable, and hashes
are identical on all platforms (little / big endian).
