Michael Paquier 9ccc049dfe pg_buffercache: Add pg_buffercache_mark_dirty{,_relation,_all}() 
This commit introduces three new functions for marking shared buffers as
dirty by using the functions introduced in 9660906dbd:
* pg_buffercache_mark_dirty() for one shared buffer.
- pg_buffercache_mark_dirt_relation() for all the shared buffers in a
relation.
* pg_buffercache_mark_dirty_all() for all the shared buffers in pool.

The "_all" and "_relation" flavors are designed to address the
inefficiency of repeatedly calling pg_buffercache_mark_dirty() for each
individual buffer, which can be time-consuming when dealing with with
large shared buffers pool.

These functions are intended as developer tools and are available only
to superusers.  There is no need to bump the version of pg_buffercache,
4b203d499c having done this job in this release cycle.
