[Pgpool-committers] pgpool - pgpool-II: Add pool_relcache.c to Makefile.am.

[User T-ishii]

Log Message:
-----------
Add pool_relcache.c to Makefile.am.
Refactor need_insert_lock to use pool_search_relcache and friends.
Add LocalSessionId to child.c which manage per session counter of
relcache. 
Allow to use temp tables with master/slave mode. Parse() failed.
since Parse() was always sent to master and slave and slave
does not have the temp table. To fix this, is_temp_table() added
to pool_proto_modules.c which inquire particular table is a temporary
one or not when INSERT/UPDATE/DELETE. If it's a temporary table,
parse message is sent to only master. Note that /*NO LOAD BALANCE*/
directive can be used to control this.
SELECT still needs /*NO LOAD BALANCE*/. It's hard to find all tables
in a SELECT statement.
