Extend when requested, release when being replaced.
Separate address families so that one can be granted even when the
pool for the other is empty.

|
Makes it easier to test with many peers.

Before this, leases_ht would store the (temporary) pointer to pubkey
that's given to new_lease() directly. The memory it's pointing to is
overwritten as soon as a new connection comes in however and thus
breaking the hashtable.
Instead make our own copy of the pubkey and store the pointer to that.

Pools are created from routes which can overlap. Consider the following:
ip route add 192.168.4.0/28
ip route add 192.168.4.0/24
sleep 3600
ip route del 192.168.4.0/24
Here, the pool created from the first route is being shadowed by the
pool from the second route. However, since the second pool is later
removed again we cannot simply combine them. So instead this commit
shadows them, to avoid them being double counted.

The way find_node() was written to suit ipp_addpool() means it's not
really generic and rather confusing, so we inline it instead.
|
|
This enables us to later use the timeout parameter of epoll_wait() to
timely remove expired leases.

The link-local IP is always /128, so using a hashtable is more
appropriate here. We only use the lower 64 bits as key, since the first
64 bits of link-local addresses are always the same.
|
|
Only sleep after failed try_connect(), because it might fail quickly.
The read should be blocking for 1s (SO_RCVTIMEO).
|
|
Avoiding the unnecessary complexity of non-blocking I/O.

POSIX says:
"In each pollfd structure, poll() shall clear the revents member,
except that where the application requested a report on a condition by
setting one of the bits of events listed above, poll() shall set the
corresponding bit in revents if the requested condition is true."
