[pgpool-committers: 7778] pgpool: Fix maximum length of hostnames including domain name.

[Tatsuo Ishii]

Fix maximum length of hostnames including domain name.

The maximum length of hostnames was 128, which is not incorrect.
Moreover there were multiple places where the maximum length of hostname is defined.
So create unified definition of it in libpcp_ext.h.
