[Pgpool-hackers] pgpool_adm functions added

[Tatsuo Ishii]

Hi,

I have committed pg_adm functions written by Jehan-Guillaume (ioguix)
de Rorthais under pgpool_adm directory. Thank you for the
contribution!

Here are some issues I notice so far:

- Compiler warning:

$ LANG=C make USE_PGXS=1 
gcc -O2 -Wall -Wmissing-prototypes -Wpointer-arith -Wdeclaration-after-statement -Wendif-labels -fno-strict-aliasing -fwrapv -fpic -I/usr/local/pgsql/include -I. -I. -I/usr/local/pgsql/include/server -I/usr/local/pgsql/include/internal -D_GNU_SOURCE   -c -o pgpool_adm.o pgpool_adm.c
pgpool_adm.c: In function 'check_pcp_conninfo_props':
