Add HBA config file support, add hba reload logic.
Currently supported:
local/host/hostssl/hostnossl
IPv4/IPv6 address ranges
rules reload on receiving SIGHUP
simple tests
What to improve:
default db/user
@<file> support in db/user fields
? set auth method for each hba rule
? replace rw_lock with coroutine synchronization
? make parser kind of configurable
