Tom Lane e04a8059a7 Simplify declaring variables exported from libpgcommon and libpgport.
This reverts commits c2d1eea9e and 11b500072, as well as similar hacks
elsewhere, in favor of setting up the PGDLLIMPORT macro so that it can
just be used unconditionally.  That can work because in frontend code,
we need no marking in either the defining or consuming files for a
variable exported from these libraries; and frontend code has no need
to access variables exported from the core backend, either.

While at it, write some actual documentation about the PGDLLIMPORT
and PGDLLEXPORT macros.

Patch by me, based on a suggestion from Robert Haas.

PostgreSQL Database Management System
=====================================

This directory contains the source code distribution of the PostgreSQL
database management system.

PostgreSQL is an advanced object-relational database management system
that supports an extended subset of the SQL standard, including
transactions, foreign keys, subqueries, triggers, user-defined types
and functions.  This distribution also contains C language bindings.

PostgreSQL has many language interfaces, many of which are listed here:

	https://www.postgresql.org/download/

See the file INSTALL for instructions on how to build and install
PostgreSQL.  That file also lists supported operating systems and
hardware platforms and contains information regarding any other
software packages that are required to build or run the PostgreSQL
system.  Copyright and license information can be found in the
file COPYRIGHT.  A comprehensive documentation set is included in this
distribution; it can be read as described in the installation
instructions.

The latest version of this software may be obtained at
https://www.postgresql.org/download/.  For more information look at our
web site located at https://www.postgresql.org/.
