pgsql: I've created a new shared catalog table pg_shdescription to store

Log Message:
-----------
I've created a new shared catalog table pg_shdescription to store
comments on cluster global objects like databases, tablespaces, and
roles.

It touches a lot of places, but not much in the way of big changes. The
only design decision I made was to duplicate the query and manipulation
functions rather than to try and have them handle both shared and local
comments. I believe this is simpler for the code and not an issue for
callers because they know what type of object they are dealing with.
This has resulted in a shobj_description function analagous to
obj_description and backend functions [Create/Delete]SharedComments
mirroring the existing [Create/Delete]Comments functions.

pg_shdescription.h goes into src/include/catalog/
