c9e3a0669f sched_backtrace: define sched_dumpstack when not enable SCHED_BACKTRACE 
Before directly use sched_backtrace() with SCHED_BACKTRACE disable will
lead compile error, this commit avoid this problem by define
sched_backtrace to 0 when CONFIG_SCHED_BACKTRACE not enable.

82debdc213 Make task_init() and task_activate() internal OS functions. 
-Move task_init() and task_activate() prototypes from include/sched.h to include/nuttx/sched.h.  These are internal OS functions and should not be exposed to the user.
-Remove references to task_init() and task_activate() from the User Manual.
-Rename task_init() to nxtask_init() since since it is an OS internal function
-Rename task_activate() to nxtask_activate since it is an OS internal function

2. Remove pthread-specific data functions from syscalls.
3. Implement tls_alloc() and tls_free() with system calls.
4. Reimplement pthread_key_create() and pthread_key_free() using tls_alloc() and tls_free().
5. Reimplement pthread_set_specific() and pthread_get_specicif() using tls_set_value() and tls_get_value()

2def8035db sched/sched/sched_getcpu.c: Implement non-standard interface. 
If SMP is enabled this function will return the number of the CPU that the thread is running on.  This is non-standard but follows GLIBC if __GNU_SOURCE is enabled.  The returned CPU number is, however, worthless since it returns the CPU number of the CPU that was executing the task when the function was called.  The application can never know the true CPU number of the CPU tht it is running on since that value is volatile and change change at any time.

e24f281401 This commit adds a new internal interfaces and fixes a problem with three APIs in the SMP configuration. The new internal interface is sched_cpu_pause(tcb). This function will pause a CPU if the task associated with 'tcb' is running on that CPU. This allows a different CPU to modify that OS data stuctures associated with the CPU. When the other CPU is resumed, those modifications can safely take place. 
The three fixes are to handle cases in the SMP configuration where one CPU does need to make modifications to TCB and data structures on a task that could be running running on another CPU.  Those three cases are task_delete(), task_restart(), and execution of signal handles.  In all three cases the solutions is basically the same:  (1) Call sched_cpu_pause(tcb) to pause the CPU on which the task is running, (2) perform the necessary operations, then (3) call up_cpu_resume() to restart the paused CPU.
