67ab8d1385 New test case "fotest" for fail-over of cbs to freelist in mvff. (plus stub for mvt.) need some testing hooks in mvff and mvt for getting the cbs. 
This reveals a couple of bugs in MVFF: (i) if CBSDelete fails, this might be because the block is actually on the Freelist instead; (ii) we can't SegFree before calling FreelistDelete because the Freelist needs access to the memory in order to read its pointers.

5fb6436dd0 Cbsdelete() now returns the isolated contiguous range that was found, even if the requested deletion operation cannot be performed. (this is so that the caller can try deleting the whole block instead and manage the fragments using a fallback strategy.) 
CBSFindLargest() takes a size argument, so that the caller doesn't have to re-insert the found block if it wasn't large enough.

* Mention each target once (this makes it more reliable to modify the set of targets).
* Include exposet0, expt825 and xmess in the automatically run test cases.
* For other test cases, explain why not included in automated test suite.
* Organize targets alphabetically (this is makes it easier to check the lists against each other).

In cbs.c: use $U for Booleans ($B is for bit tables).
