[pgpool-committers: 2129] pgpool: Add new parameter "allow_sql_comments".

[Tatsuo Ishii]

Add new parameter "allow_sql_comments".

SQL comments (/* ... */) effectively prevent load balancing and query
cache because pgpool-II strictly checks if the query starts with
"SELECT...". The new parameter removes the restriction and allows to
use SQL comments without disturbing load balancing and query
cache. For backward compatibility sake, the default is off.
