Description

The IO library uses a POSIX key to store an optional POSIX user environment pointer. This pulls in the POSIX keys support in every application configuration. Add a user environment pointer to the thread control block (TCB) instead. Applications which do not need the POSIX user environment will just get an overhead of one pointer per thread.
