Adds policy checks the raise the minimum C++ version to C++14
and the minimum GCC version to GCC 5
Updates the docs to indicate the C++14 minimum.

Abseil's own tests now are disabled if either BUILD_TESTING
or a new option called ABSL_BUILD_TESTING is false.
Additionally, Abseil's CMakeLists.txt no longer re-declares
the BUILD_TESTING option with a value of false.
Abseil had been using just the BUILD_TESTING option, since
the fix for #901. Because setting BUILD_TESTING false still
works to disable Abseil's tests, this change preserves the
behavior asked for in that issue.
Previous to that, Abseil had a project specific flag for
this, as is the typical idiom used in other projects.
The issue with BUILD_TESTING is that it is an all-or-nothing
policy. When Abseil is incorporated as a subproject, the
encompasing project has no convenient way to enable its own
tests while disabling Abseil's.
Fixes#1056
See https://github.com/abseil/abseil-cpp/issues/259 for context.
This change introduces the ABSL_PROPAGATE_CXX_STD option (default to OFF for now, though it prints a warning in CMake 2.8+ builds that a future Abseil release will default to ON). When enabled, all Abseil CMake targets will set the cxx_std_11 target meta feature (which will then propagate to targets that depend upon Abseil) rather than setting the target-level CXX_STANDARD property to CMAKE_CXX_STANDARD (which is the default value anyway), which doesn't propagate.
Updates README documentation to clarify behavior and with a different example recommendation for library projects (which should generally leave CMAKE_CXX_STANDARD to the root application project).
See https://crascit.com/2015/03/28/enabling-cxx11-in-cmake/ for a useful overview of these different CMake features surrounding C++ standard version configuration.
As of this change, you can use `-DABSL_USE_EXTERNAL_GOOGLETEST=ON -DABSL_FIND_GOOGLETEST=ON` to have Abseil use the standard CMake find_package(GTest) mechanism.

Slight restructuring of absl/random/internal randen implementation.
Convert round-keys.inc into randen_round_keys.cc file.
Consistently use a 128-bit pointer type for internal method parameters. This allows simpler pointer arithmetic in C++ & permits removal of some constants and casts.
Remove some redundancy in comments & constexpr variables. Specifically, all references to Randen algorithm parameters use RandenTraits; duplication in RandenSlow removed.

Change many distribution tests to use pcg_engine as a deterministic source of entropy.
It's reasonable to test that the BitGen itself has good entropy, however when testing the cross product of all random distributions x all the architecture variations x all submitted changes results in a large number of tests. In order to account for these failures while still using good entropy requires that our allowed sigma need to account for all of these independent tests.
Our current sigma values are too restrictive, and we see a lot of failures, so we have to either relax the sigma values or convert some of the statistical tests to use deterministic values.
This changelist does the latter.
