[pgpool-committers: 1994] pgpool: Remove fix buffer size restrictionn of pool_extract_error_messa

[Tatsuo Ishii]

Remove fix buffer size restrictionn of pool_extract_error_message().

Per bug #90 (pool_extract_error_message: not enough buffer space).
With upcoming 3.4, we can use StringInfo infrastructure, and can
remove the restriction easily. The API for the function has been
changed: returns palloc'd buffer space. To adopt this, some client
functions in pool_process_query.c and pool_auth.c have been changed.
