[pgpool-hackers: 4298] configure is removed from git repository

[Tatsuo Ishii]

Following this commit:
https://git.postgresql.org/gitweb/?p=pgpool2.git;a=commit;h=caeb3a8681d7aa0f5b24539de12d29dd5a8d9997

I removed configure from git repository (and add some .gitignore
entries).
https://git.postgresql.org/gitweb/?p=pgpool2.git;a=commit;h=91a017cfe1e9208606cc6c4cc9308b7d133ccb14

I believe that developers already run autoconf before compiling and
this change does not affect the operation.

Best reagards,
