Subject: [PATCH] gunzip: fix ordering of boundary callbacks
The boundary callback should not happen until all the uncompressed
data has been consumed. This previously seems to have worked
because normally gzip library returns "no error" instead of the
"stream end" if we extract exactly the amount of bytes remaining
in the archive. (Perhaps this was changed in new zlib.) In any
case, verification was broken with some apks due to this callback
ordering issue.
