f719851f50 Since the dynamic generation is shared between chains (for some reason) using its unified zone set, rather than keeping a special zone set per chain, which would’ve used up more zones. 
Using arena->topGen->mortality for the dynamic generation’s mortality, rather than a global variable.

e88bcc5184 Document the intention behind mps_ld_isstale rather than the implementation: it captures the intention of testing whether a particular dependency is stale (even though the implementation in fact tests whether any dependency is stale). add new function mps_ls_isstale_any for expressing the intention of testing whether any dependencey is stale. the two functions have the same implementation at present, but the separation gives us the freedom to return a more precise result from mps_ld_isstale in future.

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.
