logic if CONFIG_SCHED_TICKLESS is defined (2014-8-6).
* include/nuttx/arch.h: First cut at platform-specific interfaces
needed to support tickless OS option (2014-8-6).
* sched/Kconfig: Add a new option CONFIG_SCHED_TICKLESS to enable the
tickless OS. This is a work in progress but should be relatively
safe since the new features are only enabled by this option (Safer
but not 100% safe since it does not protect from typos and other
dumb errors) (2014-8-6).
* arch/sim/src/Makefile, up_idle.c, up_internal.h, and up_tickless.c:
Add support for a simulated interval timer support verification of
the tickless OS (2014-8-6).
* include/nuttx/arch.h: Added another tickless OS interface to get
the timer remaining on the interval timer (2014-8-6).
* include/nuttx/clock.h, sched/clock_initialize.c and clock_internal.h:
If CONFIG_SCHED_TICKLESS is defined, then the global variable
g_system_timer does not exist (2014-8-6).
* sched/Makefile: Don't build in sched_processtimer.c if
CONFIG_SCHED_TICKLESS is selected (2014-8-6).
* sched/clock_gettime.c and clock_settime.c: Use the clock_systimer()
macro, do access the g_system_timer() global directly (2014-8-6).
* sched/clock_systimer.c: Uses interval timer interfaces to get the
time if CONFIG_SCHED_TICKLESS is selected (2014-8-6).
