e814a233ed termios: Add IO control handler

55e0be3606 termios: Use IMFS nodes for new Termios devices 
This makes the new Termios devices independent of device major/minor
numbers.  It enables BSP independent Termios device drivers which may
reside in the cpukit domain.  These drivers require an IMFS and do not
work with the device file system.  However, the device file system
should go away in the future.

84e960e951 stackchk: Fix stack checker thread initialization 
Commit 0fd6f25507 relaxed the thread begin
extension execution environment.  This broke the stack check which only
partially initialized the stack pattern in its create extension.  Move
the part of the begin extension to the create extension.

df2ee9d377 arm/raspberrypi: basic BCM2836 SMP implementation. 
The BSP support is divided to startup/bspsmp_api.c file where
functions required by SuperCore are defined and BCM2836 hardware
initialization part in startup/bspsmp_init.c.

Separation is done to prevent smpfatal08 test build failure.

6e6a77a690 bsps/arm: reorganize CP15 code to allow clean and invalidate ARMv7 cache by level. 
New function arm_cp15_cache_invalidate_level and arm_cp15_cache_clean_level
can be used to maintain single cache level (instruction or data).

5c49464108 bsps/arm: remove lock in arm_cp15_set_translation_table_entries(). 
Protection by rtems_interrupt_disable() is incompatible with SMP build.
Actual page table entries manipulation function does not need locking
and disabling cache and can be run concurrently even on multiple
CPUs as long as changes do not modify same region. If the function
is called from more threads/CPUs to modify same region with different
mapping options concurrently then there is problem at another level
of virtual address space management  and has to be solved by mutex
or other locking at that level.

7ec689adc7 bsps/arm: use defines for cache type register format field. 
The change documents meaning of codes and opens
well defined way to use cache type format for cache
examination/debugging outside of arm-cp15.h file.

6da06c559f libmisc/capture: Fix the capture engine on SMP. 
This patches some issues with the capture engine:

 1. Check is the engine is open in ctrace commands.
 2. Check all record open and appends for overflow.
 3. Fix the record open to take the size of user data and
    not the record header.
 4. Use packed structs for data being written to the per
    cpu buffers.
 5. Remove direct struct access to the capture buffers to
    avoid misaligned accesses.
 6. Add support to extract records, no struct access to the
    capture buffers.
 7. Update ctrace to extract records from the capture buffers.
 8. Add support to ctrace to always print the task name if it
    has one.
 9. Add support to manage names or the lack of a name.
10. Range of minor fixes.
11. Fix a long standing bug in ctset's handling of args.

Closes #2780.
