/********************* Arena code follows *****************************
* ArenaPools are like heaps. The memory in them consists of large blocks,
* called arenas, which are allocated from the/a system heap. Inside an
* ArenaPool, the arenas are organized as if they were in a stack. Newly
* allocated arenas are "pushed" on that stack. When you attempt to
* allocate memory from an ArenaPool, the code first looks to see if there
* is enough unused space in the top arena on the stack to satisfy your
* request, and if so, your request is satisfied from that arena.
* Otherwise, a new arena is allocated (or taken from NSPR's list of freed
* arenas) and pushed on to the stack. The new arena is always big enough
* to satisfy the request, and is also at least a minimum size that is
* established at the time that the ArenaPool is created.
*
* The ArenaMark function returns the address of a marker in the arena at
* the top of the arena stack. It is the address of the place in the arena
* on the top of the arena stack from which the next block of memory will
* be allocated. Each ArenaPool has its own separate stack, and hence
* marks are only relevant to the ArenaPool from which they are gotten.
* Marks may be nested. That is, a thread can get a mark, and then get
* another mark.
*
* It is intended that all the marks in an ArenaPool may only be owned by a
* single thread. In DEBUG builds, this is enforced. In non-DEBUG builds,
* it is not. In DEBUG builds, when a thread gets a mark from an
* ArenaPool, no other thread may acquire a mark in that ArenaPool while
* that mark exists, that is, until that mark is unmarked or released.
* Therefore, it is important that every mark be unmarked or released when
* the creating thread has no further need for exclusive ownership of the
* right to manage the ArenaPool.
*
* The ArenaUnmark function discards the ArenaMark at the address given,
* and all marks nested inside that mark (that is, acquired from that same
* ArenaPool while that mark existed). It is an error for a thread other
* than the mark's creator to try to unmark it. When a thread has unmarked
* all its marks from an ArenaPool, then another thread is able to set
* marks in that ArenaPool. ArenaUnmark does not deallocate (or "pop") any
* memory allocated from the ArenaPool since the mark was created.
*
* ArenaRelease "pops" the stack back to the mark, deallocating all the
* memory allocated from the arenas in the ArenaPool since that mark was
* created, and removing any arenas from the ArenaPool that have no
* remaining active allocations when that is done. It implicitly releases
* any marks nested inside the mark being explicitly released. It is the
* only operation, other than destroying the arenapool, that potentially
* reduces the number of arenas on the stack. Otherwise, the stack grows
* until the arenapool is destroyed, at which point all the arenas are
* freed or returned to a "free arena list", depending on their sizes.
