do not reset CFA and rotation when no user provided values

If the user didn't use the -r or -f options, do not reset the
rotation and CFA values to 0 as they may now be set to something
else from the config file.  This relies on the fact that -1 is
not a valid angle or CFA identifier.
test_palette: improve automatic rotation

Always draw the palette test in landscape, but use the original
orientation to rotate by 180 degrees if the original angle was
180 or 270.
test_fill: add waveform option and use refresh by default
add setver.sh to set the version automatically
Android.mk: fix include path to libplutil
