Add TABLESPACE option to REINDEX

Browse Source 
This patch adds the possibility to move indexes to a new tablespace
while rebuilding them.  Both the concurrent and the non-concurrent cases
are supported, and the following set of restrictions apply:
- When using TABLESPACE with a REINDEX command that targets a
partitioned table or index, all the indexes of the leaf partitions are
moved to the new tablespace.  The tablespace references of the non-leaf,
partitioned tables in pg_class.reltablespace are not changed. This
requires an extra ALTER TABLE SET TABLESPACE.
- Any index on a toast table rebuilt as part of a parent table is kept
in its original tablespace.
- The operation is forbidden on system catalogs, including trying to
directly move a toast relation with REINDEX.  This results in an error
if doing REINDEX on a single object.  REINDEX SCHEMA, DATABASE and
SYSTEM skip system relations when TABLESPACE is used.
