Michael Paquier 28b5726561 libpq: Add support for Close on portals and statements
The following routines are added to libpq:
PGresult *PQclosePrepared(PGconn *conn, const char *stmt);
PGresult *PQclosePortal(PGconn *conn, const char *portal);
int PQsendClosePrepared(PGconn *conn, const char *stmt);
int PQsendClosePortal(PGconn *conn, const char *portal);

The "send" routines are non-blocking versions of the two others.

Close messages are part of the protocol but they did not have a libpq
implementation.  And, having these routines is for instance useful with
connection poolers as these can detect more easily Close messages
than DEALLOCATE queries.

The implementation takes advantage of what the Describe routines rely on
for portals and statements.  Some regression tests are added in
libpq_pipeline, for the four new routines, by closing portals and
statements created already by the tests.
