56645cdc0c Merging branch/2013-05-17/emergency with major rework of mvt, mvff, and cbs. 
Some parts of this are still ragged, and would not normally pass review, but this is a massive improvement to the existing code.

ca36e1a147 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.

0260380dd3 Rename cbstest.c to fbmtest.c (free block management test) and generalize it so that it tests both the cbs and freelist modules. 
Split FreelistFind into FreelistFindFirst and FreelistFindLast so that the interface exactly matches the CBS interface.
Fix errors in freelist.c: missing computation of size in FreelistBlockSetLimit; update linked list correct in coalesceRight case in FreelistInsert.
Avoid compiler warnings in freelist.c.
In cbs.c: use $U for Booleans ($B is for bit tables).

* Rename RangeOverlap to RangesOverlap.
* MVFF shouldn't assume that CBSInsert and CBSDelete can't fail.
* Remove unused function mps_mvff_stat.
* Don't call range methods in RangeCheck.
* RangeInit can't fail, so return void.
