Roll changes forward with ChunkIterator templatized.

This should facilitate usage of "small" chunk iterator for a regular usage and proper "big" iterator internally in Cord implementation. This way Cord users are not exposed to stack size overhead if they have a lot of chunk iterators or recursive implementation which relies on chunk iterators.

Remove top-level const from K/V in map_slot_type::mutable_value and map_slot_type::key.

This allows us to move between `map_slot_type::mutable_value`s internally even when the key_type and/or mapped_type specified by the user are const.

Don't use MSVC-specific bit manipulations when using Clang on Windows.

This fixes a compiler warning.  Note that we do not have continuous testing for this configuration; this CL is best-effort support.

Changed absl's import of std::string_view to
using string_view = std::string_view.
This should help tools (e.g. include-what-you-use) discover where absl::string_view is defined.

Use FlagValue<T> to represent the value of a flag. Place it directly after
FlagImpl and use a computed offset refer to it.

The offset is computed based on the assumption that the `value_` data member
is placed directly after the impl_ data member in Flag<T>.

This change will allow us to migrate to `T`-specific storage in the generic case.

This change decreases the overhead for int flags by 32 bytes.

68b015491f0dbf1ab547994673281abd1f34cd4b by Gennadiy Rozental <rogeeff@google.com>:

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.

Fix errors in apply() sample code

The following changes are made:
 * Make the example method public.
 * Give the two user functions different names to avoid confusion about
   whether apply() can select the correct overload of a function based
   on its tuple argument (it can't).
 * Pass tuple2 to the second example apply() invocation, instead of
   passing its contents individually.
 * Fix a s/tuple/tuple3/ typo in the third example apply() invocation.

First test if a macro is defined to avoid -Wundef.

ABSL clients may need to compile their code with the -Wundef warning
flag. It will be helpful if ABSL header files can be compiled without
the -Wundef warning.

How to avoid the -Wundef warning: If a macro may be undefined, we need
to first test whether the macro is defined before testing its value. We
can't rely on the C preprocessor rule that an undefined macro has the
value 0L.

Record rehashes in the hashtablez struct.
Only recording the probe length on insertion causes a huge overestimation of
the total probe length at any given time.

With natural growth, elements are inserted when the load factor is between
(max load/2, max load). However, after a rehash the majority of elements are
actually inserted when the load factor is less than max/2 and have a much lower
average probe length.

Also reset some values when the table is cleared.

Fix a sample code snippet that assumes `absl::string_view::const_iterator` is `const char*`.  This is generally true, however in C++17 builds, absl::string_view is an alias for std::string_view and on MSVC, the std::string_view::const_iterator is an object instead of just a pointer.
