- smolnetd: an empty ip_router (DHCP-managed or deliberately network-less like
the bare target) is a valid 'no default gateway' state, not a malformed config
-> no warning.
- router: a limited/directed IPv4 broadcast (DHCP DISCOVER to 255.255.255.255
before any lease/route exists) legitimately has no routing-table entry; don't
warn 'No route found' for broadcast destinations.
- e1000d: add the 82574L (0x10d3, QEMU '-device e1000e') to the E1000 match
list; it keeps the legacy descriptor/register interface this driver uses.
I219 is intentionally excluded (integrated MDIO PHY, different init).
- init: add condition_path_exists so optional-daemon units (dbus, seatd,
thermald, evdevd) are silently skipped when their binary is absent in a
minimal image, instead of emitting [FAILED] 'No such file or directory' on
the bare target. Boot-critical units omit the field and still hard-fail.
- ahcid: an empty ATAPI/optical drive (QEMU's default DVD-ROM, most bare-metal
optical bays) failed READ CAPACITY and logged 4 ERROR lines every boot;
register it with a zero block count as a normal no-media state and drop the
HBA register dump to debug level.
- netstack: a machine with no NIC (bare, or an unsupported NIC) logged an ERROR
and exited non-zero; treat 'no network adapter' as a normal idle state
(info + clean exit).
- dhcpd: cut the socket timeout 30s -> 8s so the network stage fails fast when
no DHCP server answers instead of stalling boot.
On success, the number of bytes written should be returned.

"down to zero" is okay as that is checked by `can_send`.

We did not update the relibc version needed for redox-rt or generic-rt.
Additionally, base @6b9593946 was missing an updated callsite for
`can_recv()`.
