freebsd compatibility

[var1ety]

only change needed was to makefilefreebsd in world and zone. Additionally, the measures committed to stop the dyasync problem weren't enough, so added ../common/dbasync.o to the dependency list.

world starts up fine, zone does also, but I have a corrupt database, so can't log in.

Also, if you're just using db.sql and no items/mobs/etc zone seems to crash now, at least for me; this is different from 0.4.1 behavior. Slapping in some more debug messages it seems like the problem is in Database::LoadLoot() somewhere, but there's no stack to be debugged.

Aye, I had the same problem.. the default empty database makes the zone server segfault on FreeBSD.
