=head1 Allocation and deallocation of SVs.

An SV (or AV, HV, etc.) is allocated in two parts: the head (struct
sv, av, hv...) contains type and reference count information, and for
many types, a pointer to the body (struct xrv, xpv, xpviv...), which
/*
Here are mid-level routines that manage the allocation of bodies out

1. SV-head arenas, which are discussed and handled above
2. regular body arenas
unused block of them is wasteful. Also, several svtypes dont have
bodies; the data fits into the sv-head itself. The arena-root
pointer thus has a few unused root-pointers (which may be hijacked
- later for arena types 4,5)
+ later for arena type 4)
3 differs from 2 as an optimization; some body types have several
unused fields in the front of the structure (which are kept in-place
are decremented to point at the unused 'ghost' memory, knowing that
the pointers are used with offsets to the real memory.

Allocation of SV-bodies is similar to SV-heads, differing as follows;
the allocation mechanism is used for many body types, so is somewhat
more complicated, it uses arena-sets, and has no need for still-live
