[Pgpool-committers] pgpool - pgpool-II: Add standard pgpool Global Development Group header

[User T-ishii]

Log Message:
-----------
Add standard pgpool Global Development Group header comments.
This was missing from the day one of the file.

Fix _rewriteGrantStmt to suppress compiler warnings.
(This is not an actual fix, just make it cleaner that we are missing some
implementations).
