* 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.

Annotate FlagImpl storage buffer
Flag type can contain legit uninitialized bits, e.g. padding.
When the code calls bit_cast as int64_t, it will contain those bits as well.
Then when we pass the int into the store it's UB for C++ and will be
reported by the new msan.

Correct the computation of contention cycles
Currently, we record contention cycles from the first time a thread started
waiting on a mutex. Consider a situation in which two threads, T1 and T2, run
a loop at the top of which they acquire a common mutex and release it at the
end of the loop body. Further assume that T2 is never able to acquire the
mutex as T1 repeatedly acquires and then releases the mutex. In this case, we
would expect that the reported contention cycles would be increase linearly
over time. But currently we observe a quadratic behavior in the reported
waiting time as mentioned in b/14684244#comment10.
To fix the issue, this CL records the contention cycles experienced by all the threads woken up when the mutex is released. Further, contention_start_cycles is set to the current time since the contention cycles for the time already passed has been taken into account. With this CL, we get a linear increase in the waiting time, the expected behavior.

Not all affected benchmarks show performance changes:

Make Cord::InlineRep::set_data unconditionally zero out memory.
Currently there is a single case where we don't zero out memory
as an optimization. Unconditional zeroing doesn't show any changes
in benchmarks, except for the unrelated improvement:

BM_CordPartialCopyToCord/8M/128k 334ns ± 3% 305ns ± 2% -8.56% (p=0.000 n=17+16)
This is clearly an alignmnet effect since number of the executed instructions is the same:

BM_CordPartialCopyToCord/8M/128k 1.44k ± 0% 1.44k ± 0% ~ (p=0.507 n=40+40)
This makes code simpler and doesn't regress performance.

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.

dynamic data from static data that is available at constructor-time.
Background: `inline_element_size` is effectively constant, but there
is a data race between its initialization and its access. We had fixed that race by making
inline_element_size atomic. This CL changes `inline_element_size`
back to a non-atomic integer, and provides a way for all profiles to
provide Register()-time values.

Revert the crc addition to RefcountAndFlags, and restore related comments to their original state.
In development, the implementation of SetExpectedCrc() changed, and there is no longer a need to track the CRC status in the refcount.
Since the distinction between IsOne() and IsMutable() is subtle *and unused*, removing it now can help avoid subtle bugs in the future. This distinction can always be added back later, if it proves necessary.
Keep the reserved bit for now; all it costs is one extra mask instruction in the refcount checks, and space for extra state in Cord is always hard to find.

Implement Cord::SetExpectedChecksum() and Cord::ExpectedChecksum().
SetExpectedChecksum() will store a uint32_t out-of-band alongside a Cord's data. This value persists through copies and assignments. Mutating operations on a Cord cause the value to be forgotten. ExpectedChecksum() retrieves the stored value, if present.
This API is intended for storing a CRC32C checksum alongside data, allowing checksums to be passed through dataflows and validated at the final step. However, this API is agnostic to the meaning of the stored value. No CRC32C validation is performed by these new APIs.
This implementation adds a new CordRep node, CordRepCrc. A CordRepCrc may (currently) only live at the top of a tree. This allows traversal logic to be agnostic to these nodes, instead putting the needed branches at the mutation level. This also implements the property requested from API review, that any mutation is guaranteed to permanently forget the stored CRC.

Add 'Rebuild' logic to CordRepBtree
There are btree hostile scenarios where an application could perform repeated split/insert/merge operations on a cord leading to a tree exceeding the maximum height. While this should be rare in practice, this change adds a Rebuild() method that will rebuild a tree with a 100% fill factor, and we will invoke this rebuild when a tree exceeds the maximum height. This basically follows the similar 'balance' logic in Concat trees (although the latter is common in Concat uses)

9957af575c33bb18dc170572a4ee8cc5901df6b2 by Greg Falcon <gfalcon@google.com>:
Initial groundwork to allow storing checksum data inside CordRep instances.
This uses a RefcountAndFlags bit that was reserved for this purpose, and will be leveraged in a follow-up change to allow attaching checksums to a Cord's value.
This change splits RefcountAndFlags::IsOne() into two distinct operations:
* IsOne(): This returns true when the associated CordRep is not shared with other threads. This is useful for functions that consume CordRep instances; for example, code that consumes an unshared CordRep can assume ownership of its children without modifying those refcounts.
* IsMutable(): This returns true when the associated CordRep reference is not shared with other threads, *and* does not store an associated checksum value. This is useful for functions that modify a CordRep's contents: code may modify the bytes of a mutable-unshared CordRep without fear of races with other threads, or of invalidating a stored checksum.
The tricky part of this CL is ensuring that the correct choice between IsMutable() and IsOne() was made at each point. An incorrect application of IsOne() could lead to correctness bugs in the future. Code conditioned on IsOne() may delete the CordRep in question, or assume ownership of its children, but must not modify the CordRep's data without explicitly adjusting the CRC.

Prefetch while hashing.
While we may not need to access the cacheline *ctrl_ is on once we've computed the hash, we can begin to resolve the TLB required for the hashtable's heap allocation simultaneously with computing the hash value for the key.

Fix a bug in the right shift of negative numbers for the no_intrinsic code path
If the right shift was greater than or equal to 64 bits the the most significant 64 bit would always be initialized to zero. The code now initializes the most significant int64 to all ones if the architecture does arithmetic rights shifts and the number was negative.

debugging: add support for non-glibc targets for debugging
This relaxes the ELF mem_image handling and subsequently enables the VDSO
support for non-glibc targets. The primary need for the restriction was the
use of the `__GLIBC_PREREQ` macro. If it is undefined, assume that the glibc
pre-requisite is unavailable. This allows building the debugging_internal
target on musl targets.
