Extents: Break extent-struct/arena interactions Specifically, the extent_arena_[g|s]et functions and the address randomization. These are the only things that tie the extent struct itself to the arena code.

Add element acquire/release capabilities to rtree. This makes it possible to acquire short-term "ownership" of rtree elements so that it is possible to read an extent pointer *and* read the extent's contents with a guarantee that the element will not be modified until the ownership is released. This is intended as a mechanism for resolving rtree read/write races rather than as a way to lock extents.

Implement retain on Windows. The VirtualAlloc and VirtualFree APIs are different because MEM_DECOMMIT cannot be used across multiple VirtualAlloc regions. To properly support decommit, only allow merge / split within the same region -- this is done by tracking the "is_head" state of extents and not merging cross-region. Add a new state is_head (only relevant for retain && !maps_coalesce), which is true for the first extent in each VirtualAlloc region. Determine if two extents can be merged based on the head state, and use serial numbers for sanity checks.

Protect the rtree/extent interactions with a mutex pool. Instead of embedding a lock bit in rtree leaf elements, we associate extents with a small set of mutexes. This gets us two things: - We can use the system mutexes. This (hypothetically) protects us from priority inversion, and lets us stop doing a backoff/sleep loop, instead opting for precise wakeups from the mutex. - Cuts down on the number of mutex acquisitions we have to do (from 4 in the worst case to two). We end up simplifying most of the rtree code (which no longer has to deal with locking or concurrency at all), at the cost of additional complexity in the extent code: since the mutex protecting the rtree leaf elements is determined by reading the extent out of those elements, the initial read is racy, so that we may acquire an out of date mutex. We re-check the extent in the leaf after acquiring the mutex to protect us from this race.

Split rtree_elm_t into rtree_{node,leaf}_elm_t. This allows leaf elements to differ in size from internal node elements. In principle it would be more correct to use a different type for each level of the tree, but due to implementation details related to atomic operations, we use casts anyway, thus counteracting the value of additional type correctness. Furthermore, such a scheme would require function code generation (via cpp macros), as well as either unwieldy type names for leaves or type aliases, e.g. typedef struct rtree_elm_d2_s rtree_leaf_elm_t; This alternate strategy would be more correct, and with less code duplication, but probably not worth the complexity.
