2f0ef9355d Clarify tracefix logic by unwinding the nested conditions. 
Change the arena's chunk tree from a splay tree to an ordinary tree (so that it's not possible to accidentally splay it and leave it unbalanced).
New function TreeFindNext allows us to implement TractFirst and TractNext without having to splay the tree.
Make sure all operations on the chunk tree leave it balanced. But don't balance the tree directly in ChunkFinish() because this is only ever called in a loop where multiple chunks are being deleted from the tre. Instead use the sequence TreeToVine -- iterate and delete -- TreeBalance. The new macro TREE_DESTROY assists with this.
No need any more for ArenaIsReservedAddr, CHUNK_OF_ADDR, TRACT_OF_ADDR.
Update design documentation.

632ac692a5 Restore "avoid" mechanism in arenaallocpage. 
Make sure that we can tear down the arena if ArenaCreate fails:
1. Don't set hasFreeCBS until the block pool has some pages.
2. Finish the CBS block pool in ArenaFinish, not ArenaDestroy.
3. Delete the chunk from the arena's free CBS before destroying the chunk, just in case the chunk contains pages from the CBS's block pool.
