dist/orig contains the stock sqlite3 code, as packaged in the tar.gz file above.

dist contains a copy of dist/orig, but with the Android.patch file applied.

The Android specific patch didn't apply cleanly due to merge conflict in shell.c. The conflict was resolved and the patch was regenerated.

More details about the release are available here:
