libio: Add POSIX user environment pointer to TCB
The IO library used a POSIX key to store an optional POSIX user
environment pointer. This pulled 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.
Close #3882.
