commit 315c420e1becee5dc5dbe6fad5ffc1a447ea2e48
Author: Matt Joyce <matthew.joyce@embedded-brains.de>

Add _REENT_CVTLEN(ptr)
Add a _REENT_CVTLEN() macro to encapsulate access to the _cvtlen
member of struct reent. This will help to replace the struct
member with a thread-local storage object in a follow-up patch.
