This is a test app for the digest calculation of the OPFS
SAHPool VFS. It requires running it with a new database created using
v3.49.0 or older, then running it again with a newer version, then
again with 3.49.0 or older.

***********************************************************************
This is a bugfix test for the OPFS SAHPool VFS. It requires
setting up a database created using v3.49.0 or older, then
running it again with a newer version. In that case, the newer
version should be able to read the older version's db files
just fine. Revering back to the old version should also still
work - it should be able to read databases modified by the
newer version. However, a database _created_ by a version with
this fix will _not_ be legible by a version which predates
this fix, in which case the older version will see that VFS
file slot as corrupt and will clear it for re-use.
This is unfortunately rather cumbersome to test properly,
and essentially impossible to automate.
