addrenv interface changes: up_addrenv_create() may need to create .text and .bss/.data separately because of differing access privileges (read/execute vs read/write). And, as a consequence, up_addrenv_vaddr() needs to be split into up_addrenv_vtext(0 and up_addrenv_vdata().

include/nuttx/pgalloc.h and mm/mm_pgalloc.c: Add a simple page allocator based on the existing NuttX granule allocator. I am not certain if the granule allocator is sufficiently deterministic for long range use, but it gets get a page allocator in place for testing very quickly.

wdog.h does not contain any application interface, only internal OS interface. Further, it is non-standard. Move wdog.h from include/ to include/nuttx. For the same reason, move the description of the watchdog timer interfaces from the Users Guide to the Porting Guide.

Change all time conversions. Yech. New timer units in microseconds breaks all existing logic that used milliseconds in the conversions. Something likely got broken doing this, probably because I confused a MSEC2TICK conversion with a TICK2MSEC conversion. Also, the tickless OS no appears fully functional and passes the OS test on the simulator with no errors

Change CONFIG_MSEC_PER_TICK to CONFIG_USEC_PER_TICK. This gives more options for system timers in general, but more importantly, let's us realize higher resolution for the case of CONFIG_SCHED_TICKLESS=y -- of course, at the risk of some new interger overvflow problems

Audio: Change how the end of the audio stream is detected by the leaf audio component. This used by be done by looking for the first partial buffer. That does not work with the in-place sub-sampling performed by the PCM decoder: That always reduces the size of the buffer so that all buffers only partially filled by the time they get to the leaf. Now, a flag is set in the audio buffer flags set to indicate the final buffer in the stream.
