Sergey Koshelenko d88e21ff91 ndisc: fix IPv6 address lifetimes computation 
Background: when router sends router advertisement (RA) message,
NetworkManager processes it and passes data to a lower system layer.
Currently there is a problem that NetworkManager adds one second to both
valid lifetime and preferred lifetime. This happens because of the
algorithm in nm_ndisc_data_to_l3cd() function.

Let's look at an example: let current timestamp be 100450, so now_sec
variable is 100. At this moment RA message was received from the router.
The IPv6 address' valid lifetime is 200 seconds (for example), so
expiration timestamp (ndisc_addr->expiry_msec) is 300450. But after the
_nm_ndisc_lifetime_from_expiry() call, NMPlatformIP6Address lifetime
becomes 201 ((300450-(100*1000)+999)/1000). Which is wrong.

This commit fixes this behaviour by replacing
nm_utils_get_monotonic_timestamp_sec() with
nm_utils_get_monotonic_timestamp_msec() so that timestamps are
calculated more precisely.

The source code of the NetworkManager daemon.

NetworkManager is a daemon that provides a D-Bus API and a file-based API for configuring the network on a Linux host.

This is the daemon source code.
