Define a macro AT() to index into std::vector. Depending on the macro
NDEBUG, AT() is defined either as at(), providing index checking, or
as operator[], providing no checking.

Poison newly allocated memory if desired. This is potentially more
thorough that Carpet's poisoning, since it is applied to all allocated
memory. It is not applied after time level cycling, though, so it
cannot replace Carpet's poisoning.

Use double instead of size_t for memory statistics. size_t works fine
for keeping statistics on a single processor, but there can be
overflow on multiple processors. double may be inexact, but will not
overflow.

Add new parameter CarpetLib::memstat_file. If set, then memory
statistics are periodically written to this file.

Introduce a new parameter print_memstats_every. When non-zero, output
the current and total allocated amount of memory (per process).
Introduce a new parameter max_allowed_memory_MB. When more than that
amount should be allocated on the current processor, abort the run.
Only memory for grid variables counts; memory for administrative
overhead is ignored.

Introduce a new class mem<T> for memory management. Memory management
has become sufficiently complicated to move into its own class. The
class mem<T> features:
1. Allocating nelem items of type T
2. Managing contiguous regions of memory for several data<T> objects
for vector groups
3. Allowing a pointer to a memory region to be passed in, which is
used instead of allocating memory through new
4. Reference counting, so that the mem<T> object only goes away once
the last using data<T> object does not need it any more.
This makes it unnecessary to delete the first data<T> objects for a
grid function group last.
