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.

ae5a06f21b Fix review comments from <https://info.ravenbrook.com/mail/2013/05/28/22-21-11/0/>: 
* 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.

61743c36b4 On platform lii6gc, the mps needs a bunch of symbols which are not defined if the -ansi option is given to gcc. these can be enabled by defining features like _gnu_source, but all headers share a common set of features (via <feature.h>) and so all sources in the same compilation unit must turn on the same set of features. make sure this happens by turning on the features in config.h (not mpstd.h). 
Remove <string.h> from mpsi.h (not needed).

No need for <string.h> in mpsi.c (this defines a function "index" on Linux).

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.
