cy@ points out that I got parameter order backwards between definition and
invocation of the helper function.  He is totally correct.  The earlier
version of this patch predated the XFree column so this is one I introduced,
rather than the original author.

Add /i option for machine-parseable CSV output.  This allows ready copy/
pasting into more sophisticated tooling outside of DDB.

Add total zone size ("Memory Use") as a new column for UMA.

For both, sort the displayed list on size (print the largest zones/types
first).  This is handy for quickly diagnosing "where has my memory gone?" at
a high level.

the if_foreach_llm?addr(), but several drivers need counting,
so avoid copy-n-paste inside the drivers.

how the access to them is synchronized, neither reveal struct ifaddr
and struct ifmaddr.

Refactor nvdimm_spa_memattr() routine and callers to just save the value at
initialization and use the value directly.  The reference value from NFIT,
MemoryMapping, is read only once, so the associated memattr could never
change.

No functional change.

Fix process launch failure on FreeBSD after r365761

  Summary:
  After rLLDB365761, and with `LLVM_ENABLE_ABI_BREAKING_CHECKS`
  enabled, launching any process on FreeBSD crashes lldb with:

  ```
  Expected<T> must be checked before access or destruction.
  Expected<T> value was in success state. (Note: Expected<T> values in
  success mode must still be checked prior to being destroyed).
  ```

  This is because `m_operation_thread` and `m_monitor_thread` were
  wrapped in `llvm::Expected<>`, but this requires the objects to be
  correctly initialized before accessing them.

  To fix the crashes, use `llvm::Optional<>` for the members (as
  indicated by labath), and use local variables to store the return
  values of `LaunchThread` and `StartMonitoringChildProcess`.  Then,
  only assign to the member variables after checking if the return
  values indicated success.

Put in a band-aid fix for lldb 9 exiting with "Expected<T> must be
checked before access or destruction" when launching executables, while
we sort this out with upstream.
