Change `absl/base/options.h` at install time to reflect the ABI used
to compile the libraries, i.e., if Abseil was compiled with
C++ >= 17 then the `ABSL_OPTION_USE_STD_*` macros are set to `1`,
because then the C++ 17 types are embedded in the ABI of the installed
artifacts.
Likewise, set the `target_compile_features()` of Abseil libraries
to reflect the C++ version used to compile them. If they the Abseil
libraries are compiled with C++ >= 17, then all downstream
dependencies must also be compiled with C++ >= 17.

tests without requiring Abseil's tests be built (default=OFF)
This disables building libraries that are only used for writing tests
by default.
The logging library releases some libraries used for writing tests
that themselves depend on GoogleTest. This allows Abseil to build by
default without requiring GoogleTest.

When using Abseil as a dependency with CMake, files that include Abseil headers and have incompatible warning settings can emit compiler warnings. CMake allows you to mark include directories as `SYSTEM` includes, which causes compilers to ignore warnings from those headers.
This adds the new option `ABSL_USE_SYSTEM_INCLUDES`, which makes Abseil's include directories be marked with `SYSTEM`.
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.

* cmake: use target aliases from local Google Test checkout.
`ABSL_FIND_GOOGLETEST` is a dependent option, it is always `OFF` when
`ABSL_USE_EXTERNAL_GOOGLETEST` is `OFF` (i.e. when Google Test is
checked out locally).
`GTest::` target aliases are to be added only if `find_package(GTest)`
has been actually used.
* cmake: clarify adding GTest:: aliases.
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.

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.

Accept e.g. ".__uniq" as a valid clone name. Further, bring the implementation
on par with libiberty's demangler grammar.
Clang introduced option -funique-internal-linkage-names that adds the suffix
".__uniq.[0-9]+" to internal linkage functions to give them a globally unique
identifier. The suffix was designed to work with existing demanglers which do
recognize a "_" along with the alphanumeric string. This change enhances the
demangler to allow "_" with the alphanumeric string.
Please refer to libiberty's cp-demangle.c where function d_clone_suffix
implements the demangling of clone suffixes :
1. '_' is accepted as a valid character with the alphanumeric sequence.
2. The alphanumberic sequence is optional.
3. The digit sequence is optional.

Remove the MockingBitGenBase base class in favor of type-erasure in BitGenRef.
In Abseil random, mocking was split across two different classes,
MockingBitGenBase and MockingBitGen. This split existed because Google Mock is a
test-only library that we don't link into production, so MockingBitGenBase
provided a low-overhead scaffold used to lookup mocks when in test code, but
which is unused in production code.
That has been replaced by type-erasure which looks for a method named
CallImpl with the correct signature.
Weaken the coupling between MockingBitGen, DistributionCaller, and MockOverloadSet.
Rename CallImpl to InvokeMock()
Previously, the implementation of DistributionCaller was also split across different files using explicit instantiation of the DistributionCaller struct and some details in the Mocking classes. Now Distribution caller uses the presence of the InvokeMock() method to choose whether to use the mockable call path or the default call path.

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.
