Zygo Blaxell 333aea9822 lib: introduce Spanner, a pointer and size delimiting a range ...

Spanner<Iterator> turns a pair of pointers into a sequence container
with several of vector's methods.

A partial specialization of make_spanner is provided which uses
shared_ptr as the beginning of the range.  Some of the Spanner code
is a questionable hack in support of this.

C++20 has ranges and span, but neither is worth moving the minimum
C++ standard forward.
