0048f341e0 Arenafinalize now asserts that the object belongs to a finalizable (attrgc) pool. (it's a programming error to try to register a non-finalizable object for finalization.) 
Can't test this behaviour via the smoke tests, unfortunately.
Document the performance problem with mps_definalize, so that users aren't tempted into using it inappropriately.

6d30195657 Better user documentation for generation chains: 
* In the pool class properties table, note whether a pool class uses generational garbage collection.
* The arena has a default generation chain.
* The MPS_KEY_CHAIN keyword argument is now optional when creating an AMC, AMCZ or AMS pool.
* The pool classes AWL and LO now take an optional MPS_KEY_CHAIN keyword argument.
* The pool classes AMS, AWL and LO now take an optional MPS_KEY_GEN keyword argument specifying the generation for new objects.
* Remove material about generation chains from the user guide (just use the arena's default generation chain).

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.

2cf1861e8d Improvements to clarity of weak hash table implementation: 
* TAG_SIZE was changed to TAG_COUNT in the code, so make the corresponding change in the manual.
* Avoid the "+= 2" hack: use TAG_COUNT(UNTAG_COUNT(...) + 1). Clarity is more important than speed here.
* Use obj_unused for unused hash table entries so that there can be no confusion between NULL meaning "unused" and NULL meaning "splatted by the garbage collector".
* Add references from the example code to the notes.
