Replace use of atomic+global Mutex+bool with absl::call_once for Flag initialization.

This simplifies the initialization logic and helps with upcoming work with value storage rework.

Separate const bits from mutable bits.

Since bit field is not atomic unit for reading/writing, we can't have constant bits which are not protected by data guard to share the space with mutable bits which are protected.

This CL just reorder fields in class and does not make any other changes.

Eliminate Flag's destroy method.

The Abseil Flags are never destroyed. The only place where Destroy method was invoked was in some obscure place during flag registration, where we faces with duplicate retired flag registration. Regired Flag destruction is empty anyway. so we can just delete the duplicate object. The FLagImpl::Destroy is never invoked.

Re-enable type mismatch check, which works in all the cases including shared libraries.

We will use RTTI in case when our hand written approximation of it reports a type mismatch. This way we can ensure that if a flag is defined in one shared object and referenced in another we do not report spurious errors.

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.

Separate the initialization of NumCPUs() and NominalCPUFrequency()

The OSS version of Abseil never needs to call NominalCPUFrequency().
In some configurations, initializing NominalCPUFrequency() requires
spending at least 3ms measuring the CPU frequency. By separating the
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

Removes the static initializer for LookupTables<absl::uint128>::kVmaxOverBase

Uses template specialization to hard code the resulting array.

Static initializers are problematic for a number of reasons. Not only
are they responsible for the static initialization order fiasco, but
they are in the critical path during program startup. For these
reasons, the Google C++ style guide strongly discourages them (and
forbids them when they are not trivially destructible), and Chromium
even has a test forbidding them.

Step 1 of 2 to fix our CCTZ fork to respect inline namespaces.

CCTZ uses a linker flag to simulate weak symbol support in MSVC.  This takes the form of a #pragma that includes the mangled names of two types: the symbol to treat as weak, and the symbol to use as its default value if no override is provided.

When Abseil is configured to use inline namespaces, the mangled names of these symbols change, and the pragma should change to reflect that.  Fortunately for us, MSVC name mangling is simple enough that we can generate the needed string literals in the preprocessor.

This CL introduces the new macros; the uses will be introduced in a follow-up CL.

Deflaking MockingBitGen test. Because MockingBitGen can return random values,
it is inherently flaky. For log-unifrom, 2040 is a common enough value that
tests failed unreasonably frequently. Replacing it with a significantly larger
value so as to be much less common. 50000 is a good choice because it is (tied for) the least likely to occur randomly from this distribution, but is still in the distribution.

Remove construction tests for the internal `CompressedTuple<std::any>` instantiation. This was not guaranteed to work for the reasons that `std::tuple<std::any>` copy construction does not actually work by standard specification (some implementations introduce workarounds for this). In GCC9, `CompressedTuple<std::any>` and `std::tuple<std::any>` both fail for the same reasons, and a proper "fix" requires updating `std::any`, which is out of our control.

Enable compile-time enforcement that absl::Substitute patterns to not contain unescaped $ symbols.

absl::Substitute already considers unescaped $ symbols undefined behavior and crashes when it's passed them in debug builds.  Some code isn't ever built in debug mode, though, and inadvertently used some unescaped $ symbols, which led to surprising results.  This change will prevent that problem from happening in the future.

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.

Implementation detail change.

Introduce ABSL_NAMESPACE_BEGIN and _END annotation macros which indicate the beginning and end of a `namespace absl` scope.  Currently these do nothing, but they will be used to inject an inline namespace for LTS builds (to avoid symbol collisions against other Abseil versions).

These macros should not be used by end users, because end users should never write `namespace absl {` in their own code.

This CL applies these annotations to all code under //absl/base/.  The rest of Abseil will be annotated in this way in follow-up CLs.

Eliminate the pointer in absl::Flag, which points to n space where we were storing flag's default value. We also eliminate additional (now unnecessary) allocation for flag's default value.
Instead we'll initialize the flags value directly from the value specified in ABSL_FLAG.
If the default value is updated via the call to SetCommandLineOptionWithMode we are replacing pointer to initialization routine to pointer to new default value.

Improves/fixes feature detection in thread_identity

Only use ABSL_PER_THREAD_TLS_KEYWORD when it is supported (previously
on some platforms it evaluated to nothing, which completely breaks
everything), but prefer it to thread_local since benchmarks indicate
it is slightly faster in this critical code path.

Disable the calls to pthread_sigmask on MinGW where it is not
supported.

of these is the cause of https://github.com/abseil/abseil-cpp/issues/396. In

The f->header.magic check in LowLevelAlloc::Free() is redundant, because

Also fix a typo in the comment that documents the lock requirements for
Next(). The comment should say "L >= arena->mu", which is equivalent to
EXCLUSIVE_LOCKS_REQUIRED(arena->mu).

NOTE: LowLevelAlloc::Free() performs the f->header.magic check without
holding the arena lock. This may have caused the TSAN data race warning

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.

By default CMake's `add_library` creates the target as a static

by removing the explicit `STATIC` in our usages of `add_library`.

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:

Tweak ABSL_PREDICT_TRUE slightly, for better code on some platforms and/or
optimization levels.  "false || (x)" is more verbose than "!!(x)", but
ultimately more efficient.

For example, given this code:

}

Clang with default optimization level will produce:

a9ac6567c0933d786d68c10011e3f3ff9deedf89 by Greg Falcon <gfalcon@google.com>:

Add absl::FunctionRef, a type analogous to the proposed C++23 std::function_ref.

Like std::function, FunctionRef can be used to type-erase any callable (invokable) object.  However, FunctionRef works by reference: it does not store a copy of the type-erased object.  If the wrapped object is destroyed before the FunctionRef, the reference becomes dangling.

FunctionRef relates to std::function in much the same way that string_view relates to std::string.

Because of these limitations, FunctionRef is best used only as a function argument type, and only where the function will be invoked immediately (rather than saved for later use).  When `const std::function<...>&` is used in this way, `absl::FunctionRef<...>` is a better-performing replacement.

Support using Abseil with the musl libc implementation.

Only test changes were required:
  * Workaround for a bug in sigaltstack() on musl
  * printf-style pointer formatting (%p) is implementation defined,
    so verify StrFromat produces something compatible
  * Fix detection of feenableexcept()

Introduce a type alias to work around an nvcc bug.

On the previous code, nvcc gets confused thinking that T has to be a parameter
pack, as IsDecomposable accepts one.

Fix potential integer overflow in the absl time library.

In absl::FromTM, the tm.tm_year is added by 1900 regarding that tm.tm_year represents the years since 1900. This change checks integer overflow before doing the arithmetic operation.

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.
