This moves/renames some of the functions defined in pg_numa.c: * pg_numa_get_pagesize() is renamed to pg_get_shmem_pagesize(), and moved to src/backend/storage/ipc/shmem.c. The new name better reflects that the page size is not related to NUMA, and it's specifically about the page size used for the main shared memory segment. * move pg_numa_available() to src/backend/storage/ipc/shmem.c, i.e. into the backend (which more appropriate for functions callable from SQL). While at it, improve the comment to explain what page size it returns. * remove unnecessary includes from src/port/pg_numa.c, adding unnecessary dependencies (src/port should be suitable for frontent). These were either leftovers or unnecessary thanks to the other changes in this commit. This eliminates unnecessary dependencies on backend symbols, which we don't want in src/port.

The PostgreSQL contrib tree
---------------------------
This subtree contains porting tools, analysis utilities, and plug-in
features that are not part of the core PostgreSQL system, mainly
because they address a limited audience or are too experimental to be
part of the main source tree. This does not preclude their
usefulness.
User documentation for each module appears in the main SGML
documentation.
When building from the source distribution, these modules are not
built automatically, unless you build the "world" target. You can
also build and install them all by running "make all" and "make
install" in this directory; or to build and install just one selected
module, do the same in that module's subdirectory.
Some directories supply new user-defined functions, operators, or
types. To make use of one of these modules, after you have installed
the code you need to register the new SQL objects in the database
system by executing a CREATE EXTENSION command. In a fresh database,
you can simply do
CREATE EXTENSION module_name;
See the PostgreSQL documentation for more information about this
procedure.
