that the argument is not `nullptr`.
Passing `nullptr` to the single-argument constructor of `std::string_view`
is undefined behavior. `absl::string_view` has long accepted `nullptr` arguments
to the single-argument constructor. This debug assert will assist users in
finding uses of `absl::string_view(nullptr)` to allow migration to
`std::string_view`.
If you find that this assert is firing, consider using
`absl::NullSafeStringView` to safely construct the `string_view`.

Prior to this change, some ABSL_HARDENING_ASSERTs were sequenced with the main
work of some constexpr methods using the comma operator in order to satisfy
C++11's constexpr requirements. However, putting the assertion and the main
work of the function on the same line complicates measuring the performance
impact of the assertions. As C++11 is no longer supported, this change moves
the assertions to their own lines in order to make measuring their performance
impact easier.

Fix CordRepRing diabolical growth
The 'Mutable' function in CordRepRing was over-eager in doubling capacity, which lead to 'ludicrous' growth in the diabolical test case as added to cord_test. This CL fixes the doubling for growing shared reps, and tempers CordRepRing growth for non shared capacity to 1.5 instead of 2, which is more inline with a conservative growth we also have in tree cord.
After this change, CordRepRing no longer swamps the heap into the shadow realm, and is in effect reducing the memory used compared to the tree implementation. With a diabolical 5000 bytes growth pattern:
Tree cord: 1523520 bytes
Ring cord: 274232 bytes

Add an option to build Abseil in hardened mode
In hardened mode, the ABSL_HARDENING_ASSERT() macro is active even
when NDEBUG is defined. This allows Abseil to perform runtime checks
even in release mode. This should be used to implement things like
bounds checks that could otherwise lead to security vulnerabilities.
Use the new assertion in absl::string_view and absl::Span to test it.

Improve ABSL_ATTRIBUTE_PACKED documentation
Recommend to apply ABSL_ATTRIBUTE_PACKED to structure members instead of to an entire structure because applying this attribute to an entire structure may cause the compiler to generate suboptimal code. It reduces the alignment of the data structure from a value larger than one to one. When applied to a structure, ABSL_ATTRIBUTE_PACKED reduces the alignment of a structure (alignof()) to 1. As a result, the compiler can no longer assume that e.g. uint32 members are aligned on a four byte boundary and hence is forced to use single-byte load and store instructions on CPU architectures that do not support non-aligned loads or stores.

The OSS version of Abseil never needs to call NominalCPUFrequency().

initialization from NumCPUs(), which is called in most configurations,
we can save at least 3ms of program startup time.

Enable building Abseil as a DLL.
This is currently experimental and unsupported.
This CL does a few things:
1. Adds the ABSL_DLL macro to any class holding a static data member, or to global constants in headers.
2. Adds a whitelist of all files in the DLL and all the build targets that are conglomerated into the DLL.
3. When BUILD_SHARED_LIBS is specified, any build target that would be in the DLL still exists, but we swap out all of it's dependencies so it just depends on abseil_dll

This CL introduces following changes to the class FlagImpl:
* We eliminate the CommandLineFlagLocks struct. Instead callback guard and callback function are combined into a single CallbackData struct, while primary data lock is stored separately.
* CallbackData member of class FlagImpl is initially set to be nullptr and is only allocated and initialized when a flag's callback is being set. For most flags we do not pay for the extra space and extra absl::Mutex now.
* Primary data guard is stored in data_guard_ data member. This is a properly aligned character buffer of necessary size. During initialization of the flag we construct absl::Mutex in this space using placement new call.
* We now avoid extra value copy after successful attempt to parse value out of string. Instead we swap flag's current value with tentative value we just produced.

Implement the config options for our four main C++ forward compatibility types.
These options control whether the names `any`, `optional`, `string_view`, and `variant` in namespace `absl` are aliases to the corresponding C++17 types in namespace `std`. By default, we continue to auto-detect the configuration of the compiler being run.
These options are not intended to be modified on the command line (as -D flags, say). Instead, the options.h file can be modified by distributors of Abseil (e.g., binary packagers, maintainers of local copies of Abseil, etc.)
Changing options will change Abseil in an ODR sense. Any program must only link in a single version of Abseil. Linking libraries that use Abseil configured with different options is an error: there is no ABI compatibility guarantee when linking different configurations, even if the Abseil versions used are otherwise exactly identical.

Avoid our is_[copy/move]_assignable workarounds in MSVC 19.20 and on, since that release introduces a regression that breaks our workaround. We should ideally use the std forms in more cases, but branching when our workarounds fail is simpler to maintain.

Use explicit static_cast<double> for int64_t to double conversion
This uses an explicit static_cast<double>() in the int64_t to double comparisons in duration.cc's SafeAddRepHi. This satisfies clang's -Wimplicit-int-to-float-conversion warning (with https://reviews.llvm.org/D64666). This may also make it easier for humans to realize that the comparison is happening between two floating point double precision values. It should have no impact on the behavior or generated code.
Tested:
No behavior change

Try to become idle only when there is no wakeup.
Immediately after waking up (when futex wait returns), the current thread tries
to become idle doing bunch of memory loads and a branch. Problem is that there
is a good chance that we woke up due to a wakeup, especially for actively used
threads. For such wakeups, calling MaybeBecomeIdle() would be a waste of
cycles.
Instead, call MaybeBecomeIdle() only when we are sure there is no wakeup. For
idle threads the net effect should be the same. For active, threads this will
be more efficient.
Moreover, since MaybeBecomeIdle() is called before waiting on the futex, the
current thread will try to become idle before sleeping. This should result
in more accurate idleness and more efficient release of thread resources.
