contain the requested zone.
And now that we have a fallback at all, remove the special case that
allowed for testing absl::LocalTimeZone() under TZ=US/Pacific.
And we might as well update the existing embedded data while we're here.
This is modifying the test framework only.

For portability, absl_time_test builds a small, incomplete tzdata
database into the test binary and uses that instead of the system tzdata
database. (absl_time_test needs to run on some platforms that lack a
system tzdata database.) However, this causes issues if TZ is set to
something that isn’t in the test database. To address them, fall back to
America/Los_Angeles if TZ is set to an unknown value during testing.

This fixes an overload that is ambiguous for some toolchains, because
0U does not always refer to a uint32_t (on some toolchains, uint32_t
is an unsigned long).

Many improvements to LeakChecker builds
The presence of the LeakChecker is now detected when possible. GCC
users using LeakChecker in standalone mode still need to use
-DLEAK_CHECKER. This is now documented in the header.
The hacky targets used for testing leak checking have been removed in
favor of testing in AddressSanitizer mode on Kokoro.

Add a parameter pack to absl profile to allow profiles to separate
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.

s/round/rint/ in exponential_biased
`rint` differs from `round` in that it uses the current FPU rounding
mode. It’s thus potentially faster, since it doesn’t have to save and
restore FPU state. It also is more reflective of developer intent –
most developers expect all FPU operations to use the current rounding
mode, and having exponential_biased follow that rule seems ideal.

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

Implement FuzzingBitGen, an adapter which allows existing randomized tests which use absl::BitGenRef to easily integrate with fuzz testing.
I found myself implementing a similar option in our tensorstore project to fuzz test a storage layer and figured that it would be more useful as a common tool with defaults that take the non-random path.
This is similar to the FuzzedDataProvider mechanism which generates random values from a fuzz string, and is used to generate fuzz test inputs, and internally it uses FuzzedDataProvider.
The basic technique used here is to construct mocking lambdas for all of the absl mock distribution configurations, and forwarding the parameters to fuzzing-specific implementations that call into FuzzedDataProvider. The default paths for the distributions are either the bounds or a median value.

Stop directly accessing CordRepFlat data via CordRep::data.
The old pattern of access breaks the `CordRep` type abstraction; since `CordRep::data` is not in general guaranteed to contain the chunk's data, we shouldn't access it that way.
This incidentally adds an assertion check (via the flat() accessor) that the CordRep is indeed flat on each such access, but a manual inspection of the code, as well as the fact that this code currently works, suggest that this is always true.)

Keep time's global state in a cacheline-aligned structure.
Keeping the global state as separate global variables results in two issues:
1) False sharing with adjacent global data (e.g., cycle clock source), since
the global fields are updated every O(10usec).
2) The hot global fields (e.g., seq and samples) can reside on different
cache lines.
To fix this, simply wrap the global data in a ABSL_CACHE_ALIGNED structure.
This is similar to what we do for MutexGlobals.

Move CordRep Ref() and Unref() logic into cord_internal.h
This change moves Ref() and Unref() logic out of cord.cc into cord_internal. The main purpose is to make upcoming ring buffer changes easier to isolate from existing cord.cc code. Notice that this removes the nullptr check from Unref() and now requires it to be non null (which held true most times). We may need to rethink if the 'unref unlikely one' is the common case: are cordreps most likely shared? This may be something between 'root' and non root nodes, i.e., is it more likely for leaf / flat nodes in large cords to be shared than top level cordreps being shared? Vice versa? Benchmarks say that we mostly shouldn't care, the caveat being that atomic ops seem more expensive on upcoming archs (arcadia) so we should error on the side of an extra IsOne() branch saving us single owned atomic ops.

Add `absl_btree_prefer_linear_node_search`
Allow keys of `btree_set`, `btree_map`, `btree_multiset`, and `btree_multimap`

```
class K {

private:
friend bool operator<(K a, K b) { return a.k_ < b.k_; }
