Add a rename test for mis-matching URI types.
Call LSM methods directly instead of using WT_DATA_SOURCE implementation.
replace tab characters with spaces.
Review rename calls, use "olduri" or "uri" instead of "oldname", use
"newuri" instead of "newname", it's a URI, not a name.
Check the documents for paired typos as well as the source.
Write some custom data source documentation based on my Berkeley DB code.
Don't drop core for any uninitialized WT_DATA_SOURCE method and report a
consistent "not supported" error.
Make a value format of "[0-9]t" an error, we're not going to support
bit maps underneath here.  I need to make the corresponding change in
test/format not to configure fixed formats with kvs, but this should
be here regardless.
