palmosemulator-3.5nb1.  Pull in some changes suggested by Thomas Runge in
PR#19006: use the pkgsrc libjpeg instead of a local copy, and patch a bug in
the serial device file descriptor handling.

Also up the emulated "CPU idle" delay from 10ms to 100ms.  For some \ 
reason the
former saturates the CPU (on a Celeron 700 system), but with the latter the
program idles at near 0%.  This patch is probably not required for native
threads.  Mileage may vary...
