[pgpool-committers: 1093] pgpool: Fix pg_md5 command crash.

[Tatsuo Ishii]

Fix pg_md5 command crash.

Fix contributed by Muhammad Usama(from [pgpool-hackers: 302])

While looking at the pgpool-II code I found a potential crash or stack
smash in pg_md5 utility.
The problem is update_pool_passwd() calls pg_md5_encrypt() function to get
the md5 password, and the password format generated by pg_md5_encrypt()
function is
"md5" followed by 32-hex digits, which sums up to 35 characters while the
host variable defined in update_pool_passwd() function to hold this
password can contain maximum 32 characters.
