chgserver: mangle server address to include confighash
Before this patch, chgserver will use the address provided by the client. The
new design is one server per confighash. This patch appends "-$confighash" to
the address the client provides. To maintain the compatibility and make sure
the client can connect to the server, a symbolic link is created at the original
address pointing to the new address.
The address is intentionally mangled at the server, instead of being pre-
calculated by some other process (eg. a previous server). In this way, we can
avoid file system race conditions.
