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.

7dc558b489 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).

71a2c572a0 Use range objects in the cbs interface instead of base, limit pairs. the idea is that freelist and cbs should offer similar interfaces so that the testing code can be shared.

e7559cf22f Rename the enumeration cbsfinddelete to finddelete in anticipation of it being shared between cbs and new freelist module. 
Since ABQDisposition enumeration only has two values, it's better to use Bool.

467c38a37a Separate block allocation from block insertion, so that cbsdeletefromtree no longer leaves the tree in an inconsistent state if allocation fails. 
Simplify the case logic in cbsDeleteFromTree to try to make it clearer.
Explain why cbsDeleteFromTree can't fail when it's called from cbsFindDeleteRange.

4b970759be Make the cbs module more abstract by removing cbsblock from the public interface. avoid re-entrancy problems by removing the callback interface. public interfaces like cbsiteratemethod now operate in terms of address ranges rather than cbsblocks. 
The functions CBSInsert, CBSDelete and CBSFind* now additionally return an "old" address range which gives the former base and limit of the block that has just been updated. This gives clients enough information to update their caches if need be.
Update CBS test and design accordingly.

82c29cfd3e Fixing up occurences of "unsigned long" in the main mps and test code so that we no longer assume that "unsigned long" is large enough for a pointer or size, or that it's the longest available integer type, since these are not true on 64-bit windows.
