prototype of a variable-size emergency allocator
The attached patch implements a new fixed-size arena, variable size object
allocator and uses it for the emergency pool (not yet for the dependent
exception allocations, but trivial to change those).
I welcome libstdc++ coding style issues pointed out and general comments
on whether this approach is fine (also unifying the dependent allocations
in here).
TODO: implement free-list sorting and merging of free-list entries
Sofar tested by forcing the use of the emergency allocator (as in the patch,
see #if 1) by bootstrapping and testing C++ (hopefully sorted out a last issue,
test re-running).
