    • Add missing #include options.h in optimization.h. · 99a3a6ae 
      options.h was already included indirectly from config.h. This CL is just to include what you use.

    • absl: fix a priority bug in CondVar wait morphing · b06ab1f3 
      Enqueue updates priority of the queued thread.
It was assumed that the queued thread is the current thread.
But it's not the case in CondVar wait morhping,
where we requeue an existing CondVar waiter on the Mutex.
As the result one thread can falsely get priority of another thread.

Fix this by not updating priority in this case.
And make the assumption explicit and checked.

    • Implement ABSL_ATTRIBUTE_PURE_FUNCTION and ABSL_ATTRIBUTE_CONST_FUNCTION · 1d83ac71 
      Pure functions have no effects except to return a value, and their
return value depends only on the parameters and global
variables. Functions of this kind can be subject to data flow analysis
and might be eliminated. In practice, this means that repeated calls
to the same function with the same arguments may be optimized away and
only evaluated once.

Const functions are similar to pure functions, but may not depend on
global variables at all.

It is an error not to use the result of a function with one of these
attributes, since these functions have no other visible effects.

Since some Abseil functions are tagged with these attributes, this is
potentially a breaking change for code that doesn't use the result of
these functions.

For example, absl::Minutes() is tagged with
ABSL_ATTRIBUTE_CONST_FUNCTION.  If, for example, the result of
absl::Minutes(n) is unused, some compilers with issue a warning or
error. If this is the case, it is likely that there is a typo in the
code, or the call can be removed.

    • Check CRC cordrep child nodes for nullptr. · 94b37802 
      Some time ago the invariant for CRC cordreps was relaxed to allow for nullptr values on empty cords with an explicit empty CRC value. The CordzInfo analysis never checked for nullptr values causing cord sampling to crash if the sampling happened to include a (very unlikely) empty Cord value.
