5d5e2cac05 Deleting some obsolete comment text about callbacks. 
Renaming cbsBlockShrink to cbsBlockShrunk and cbsBlockGrow to cbsBlockGrew, since they don't *do* those things, just record that they were done.
Tidying up Find functions, where deletion of emergency code had left some strange double nestings.

ef4c41df55 Ensure the emergency branch compiles and runs on lii6gc: 
No need for <string.h> in mpsi.c (this defines a function "index" on Linux).
Need more headers in range.c so that it will compile on its own.
Need UNUSED() declarations for some variables in cbstest.c.

2849a0bd33 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.
