If we get a user reporting this error message being shown it's pretty
useless in terms of actually debugging it since we don't know which hash
and which key are actually subject to the error.
This patch adds a new hash table callback which formats the
user-readable version of the hash key and reports it in the new message
which will look like:
"Duplicate hash table key 'blah'"
That way we will at least have an anchor point where to start the
search.
There are two special implementations of keys which are numeric so we
add specific printer functions for them.

The virConnectGetDomainCapabilities API accepts either a binary path
to the emulator, or desired guest arch. If guest arch is not given,
then the host arch is assumed.
In the case where the binary is not given, the code tried to find the
emulator binary in the existing list of cached emulator capabilities.
This is not valid since we switched to lazy population of the cache in:

qemu: stop creating capabilities at driver startup
As a result of this change, if there are no persistent guests defined
using the requested guest architecture, virConnectGetDomainCapabilities
will fail to find an emulator binary.
The solution is to stop relying on the cached capabilities to find the
binary and instead use the same logic we use to pick default a binary
per arch when populating capabilities.

The "ps2" bus is only available on certain machines like x86. On

Looking at the QEMU sources, PS/2 is only available if the QEMU binary
has the "i8042" device, so let's check for that and only allow "ps2"
devices if this QEMU device is available, or if we're on x86 anyway

Libvirt's original atomic ops impls were largely copied
from GLib's code at the time. The only API difference
was that libvirt's virAtomicIntInc() would return a
value, but g_atomic_int_inc was void. We thus use
g_atomic_int_add(v, 1) instead, though this means
virAtomicIntInc() now returns the original value,
instead of the new value.
This rewrites libvirt's impl in terms of g_atomic_int*
as a short term conversion. The key motivation was to
quickly eliminate use of GNULIB's verify_expr() macro
which is not a direct match for G_STATIC_ASSERT_EXPR.
Long term all the callers should be updated to use
g_atomic_int* directly.

Windows sockets take a SOCKET HANDLE object instead of a

does so that they use C runtime file descriptors.
While we could in theory use GSocket, it is hard to get
the exact same semantics libvirt has for its current
socket usage. Wrapping the Winsock2 APIs is thus the
easiest approach in the short term.
In changing the socke wrappers we need to re-implement
the nonblocking function too, since the GNULIB impl
