This is a heavily modified version of
https://github.com/abseil/abseil-cpp/pull/1445,
which adds some missing test libraries to the test DLL.

Unlike #1445, this change moves several global variables out of
headers that did not need to be in headers.

For instance, cord_btree_exhaustive_validation was a global
defined/declared in cord_internal, but only used in cord_rep_btree
and its test.

cordz_handle defined a queue in its header even though it wasn't needed,
which also led to ODR problems.

The Spinlock used in CordzHandle is replaced with a Mutex. This was
originally a Mutex, but Chromium asked us to change it to a Spinlock
to avoid a static initializer. After this change, the static
initializer is no longer an issue.

#1407

will just be a copy anyway. Also remove the typedef so that it is
clear from the type at the callsite that moving it isn't necessary.

When we insert a new element, when ASan is enabled, we replace the node that the new element is on in order to try to detect cases of code depending on pointer/reference-stability.

Imported from GitHub PR https://github.com/abseil/abseil-cpp/pull/1433

Some 32-bit configurations may use 64-bit time_t, which leads to different layout of userspace timespec and the one expected by SYS_futex implementation in kernel. In particular the issue occurs when using musl libc which has switched to unconditional 64-bit time_t definition.

This patch introduces custom struct timespec with two longs when old SYS_futex is used to match the kernel timespec definition.

Instantiate LogMessage::CopyToEncodedBuffer separately for literals and non-literals to save an instruction at each operator<<(string) callsite.

The operator<<s get inlined at the callsite.  The saved instruction is a 'load immediate' to put the StringType argument in a register for passing.

This does make the logging TU slightly larger, but it will be an overall size win for all but the smallest programs.  Smaller, faster code at callsites is worth it anyway.

Shrink most LOG callsites by one instruction (SysV x86_64 ABI) by dispatching to per-severity constructors and omitting the severity argument.

In that particular ABI, the empty tag structs are NO_CLASS and don't appear in the generated code.

Currently static analysis tools built using the Clang Dataflow Analysis framework can't prove that code under `switch (0) case 0:` is executed on all paths. The Clang Dataflow Analysis framework should ultimately be improved to handle these cases. In the meantime, to enable the use of such tools in their current state, we add a `default` case back to the `switch` statement in `ABSL_LOG_INTERNAL_STATELESS_CONDITION` to help them understand that the code is executed on all paths.

`AbslHashValue()` applied to a C-style array simply decays the array to a pointer and hashes that, which is very unlikely to be what the author intended.
