XmlUtils#readThisMapXml should handle null keys.

Both readThisValueXml & writeThisValueXml have been
implemented to handle values with "null" names.

Change readThisMapXml to allow such names as well, and
map them to the null key in the resulting HashMap.
readThisListXml and readThisSetXml already support
null names.

Don't try to set service.bootanim.exit

init has never allowed the bootanimation code to
set service.bootanim.exit, and has always generated the
dmesg error message

  <3>[   17.644615] init: sys_prop: permission denied uid:1003  name:service.bootanim.exit

Since setting this property has no effect and never worked, delete
the code which tries to do it.
