Coverity Id 1255518. mkdir() could fail. Check return value and return

5dff7425bd libcsupport/src/termios.c: Explicitly ignore return value (Coverity ID 1255347) 
Coverity spotted that we were ignoring a return value. But ignoring
it is intentional. Adding (void) clearly indicates it is being ignored
explicitly.

7fd5e89c96 termios: Partially hide rtems_termios_tty 
Move interrupt lock to device context and expose only this structure to
the read, write and set attributes device handler.  This makes these
device handler independent of the general Termios infrastructure
suitable for direct use in printk() support.

ef8c00bc88 termios: PR2153: New low-level device API 
Add a new low-level device API to Termios that passes the TTY structure
to the low-level device functions.  This greatly simplifies the
low-level device drivers since they are no longer forced to derive their
private data from the minor number.

It makes it possible to use the TTY low-level lock in the device driver
low-level functions which is necessary for proper SMP support.  For
example to set the attributes it is often necessary to perform a
read-modify-write operation on a control register used also by interrupt
routines.

A compatibility layer is provided to support device drivers using the
old callback functions so it is not necessary to modify existing device
drivers.

69aa33490b score: Simplify thread control initialization 
The thread control block contains fields that point to application
configuration dependent memory areas, like the scheduler information,
the API control blocks, the user extension context table, the RTEMS
notepads and the Newlib re-entrancy support.  Account for these areas in
the configuration and avoid extra workspace allocations for these areas.

This helps also to avoid heap fragementation and reduces the per thread
memory due to a reduced heap allocation overhead.

1b1be254e7 score: Thread life cycle re-implementation 
The thread deletion is now supported on SMP.

This change fixes the following PRs:

PR1814: SMP race condition between stack free and dispatch

PR2035: psxcancel reveals NULL pointer access in _Thread_queue_Extract()

The POSIX cleanup handler are now called in the right context (should be
called in the context of the terminating thread).

http://pubs.opengroup.org/onlinepubs/009695399/functions/xsh_chap02_09.html

Add a user extension the reflects a thread termination event.  This is
used to reclaim the Newlib reentrancy structure (may use file
operations), the POSIX cleanup handlers and the POSIX key destructors.
