When post-copy migration fails, the domain stays running on the
destination with a VIR_DOMAIN_RUNNING_POSTCOPY_FAILED reason. Both the
state and the reason can later be rewritten in case the domain gets
paused for other reasons (such as an I/O error). Thus we need a separate
place to remember the post-copy migration failed to be able to resume
the migration.

The parameter was only used to select which states correspond to an
active or failed post-copy migration. But these states are either
applicable to both operations or the check would just paper over a code
bug in case of an impossible combination of state and operation. By
dropping the check we can make the code simpler and also reuse existing
virDomainObjIsFailedPostcopy function and only check for active
post-copy states.

The new connect close callbacks for domains will be represented by a
virObject associated with the domain object itself.
To simplify handling the pointer to the close callback data will be done
by an immutable pointer allocated directly when allocating the
corresponding virDomainObj struct.
This patch adds the 'closecallbacks' field to virDomainObj and a
corresponding callback to allocate it into virDomainXMLOption.

When setting up QoS for a domain <interface/>, or when reporting
its statistics we may need to swap TX/RX values. This is all
explained in comment to virDomainNetTypeSharesHostView().
However, this function claims that VIR_DOMAIN_NET_TYPE_ETHERNET
also shares the 'host view', meaning the TX/RX values must be
swapped. But that's not true.
An easy reproducer is to start a domain with two <interface/>-s:
one type of network, the other of type ethernet and configure the
same <bandwidth/> for both. Reversed setting can then be observed
(e.g. via tc).

On aarch64 the 'id' file is not present for CPU cache information in
sysfs. This causes the local stateful hypervisor drivers to fail to
initialize capabilities:
virStateInitialize:657 : Initialisation of cloud-hypervisor state driver failed: no error
The 'no error' is because the 'virFileReadValueNNN' methods return
ret==-2, with no error raised, when the requeted file does not exist.
None of the callers were checking for this scenario when populating
capabilities. The most graceful way to handle this is to skip the
cache bank in question. This fixes failure to launch libvirt drivers
on certain aarch64 hardware.
