migration: Use normal VMStateDescriptions for Subsections

We create optional sections with this patch. But we already have
optional subsections. Instead of having two mechanism that do the
same, we can just generalize it.

For subsections we just change:

- Add a needed function to VMStateDescription
- Remove VMStateSubsection (after removal of the needed function
it is just a VMStateDescription)
- Adjust the whole tree, moving the needed function to the corresponding
VMStateDescription

net: remove all cleanup methods from NIC NetClientInfos

All NICs have a cleanup function that, in most cases, zeroes the pointer
to the NICState. In some cases, it frees data belonging to the NIC.

However, this function is never called except when exiting from QEMU.
It is not necessary to NULL pointers and free data here; the right place
to do that would be in the device's unrealize function, after calling
qemu_del_nic. Zeroing the NIC multiple times is also wrong for multiqueue
devices.

This cleanup function gets in the way of making the NetClientStates for
the NIC hold an object_ref reference to the object, so get rid of it.

e1000: correctly handle phy_ctrl reserved & self-clearing bits

Make phyreg_writeops responsible for actually writing their
respective phy registers, rather than rely on set_mdic() to

The only current instance of phyreg_writeops is set_phy_ctrl();
modify it to write the register on its own, while also correctly
handling reserved and self-clearing bits.

have_autoneg() does not need to check for MII_CR_RESTART_AUTO_NEG,
since the only time the flag comes into play is during set_phy_ctrl(),
and, following this patch, never actually gets written to the phy
control register.

e1000: improve auto-negotiation reporting via mii-tool

e1000: improve auto-negotiation reporting via mii-tool

Using mii-tool (on F20-live), the following output is produced:

SIOCGMIIREG on ens3 failed: Input/output error
ens3: no autonegotiation, 1000baseT-FD flow-control, link ok

The first line (SIOCGMIIREG error) is due to mii-tool's inability
to read the PHY auto-negotiation expansion register.
On the second line, "no autonegotiation" is wrong, and caused by
the absence of a flag in the link partner ability register which
would indicate that our link partner has acked us. This flag is
listed as "reserved" in the Intel e1000 manual, but mii-tool uses
it as LPA_LPACK from /usr/include/linux/mii.h.

This patch adds read access to PHY_AUTONEG_EXP and defines the
link partner ack flag, allowing mii-tool to generate output as
normally expected:

Revert "e1000/rtl8139: update HMP NIC when every bit is written"

This reverts commit cd5be5829c1ce87aa6b3a7806524fac07ac9a757.
Digging into hardware specs shows this does not
actually make QEMU behave more like hardware:

There are valid arguments backed by the spec to indicate why the version
of e1000 prior to cd5be582 was more correct: the high byte actually
includes a valid bit, this is why all guests write it last.

For rtl8139 there's actually a separate undocumented valid bit, but we
don't implement it yet.

To summarize all the drivers we know about behave in one way
that allows us to make an assumption about write order and avoid
spurious, incorrect mac address updates to the monitor.

Let's stick to the tried heuristic for 1.7 and
possibly revisit for 1.8.

We currently just update the HMP NIC info when the last bit of macaddr

from bit 0 to bit 5 when it changes the macaddr, this is the current
behavior of linux driver (e1000/rtl8139cp), but we can't do this
assumption.

The macaddr that is used for rx-filter will be updated when every bit
is changed. This patch updates the e1000/rtl8139 nic to update HMP NIC
info when every bit is changed. It will be same as virtio-net.
