dhcp3-server goes into infinite loop and fill syslog when EOF unexpectedly occurs in a pool statement.

[Guillaume Knispel]

Hi,
I encountered a bug in dhcp3-server 3.0.4-13 of Debian Etch, which
is also present in 3.0.4-14, and seems to also be in upstream 3.0.5
and 3.0.6rc2.

The problem is in a do {} while () loop in parse_pool_statement that
does not test for end of file conditions.

I attach a configuration file that demonstrate the problem and a
patch that fixes it, I hope without any bad side effect.

Cheers
