Update generated files for 4.1.0 update.

Removed the hack to do an always purge. Instead use the new decay
purging mechanism, but set the decay timeout to 0 so it always purges
without the need to change the code.

Added back the a0get function to use for huge chunk allocation patch
we use for android.
