Add support for deserializing the binary PCI/PCIe VPD format and storing

The VPD format is specified in "I.3. VPD Definitions" in PCI specs

notes, the PCI Local Bus and PCIe VPD formats are binary compatible

The aim of virSecurity rule is to discourage from using plain
virSecurityManager*() APIs within QEMU driver in favor of their
qemuSecurity*() counterparts. The reason is simple: namespaces;
virSecurityManager*() needs additional
virSecurityManagerTransactionCommit() call to enter given
namespace and do its work from there. And that's exactly what
those qemuSecurity*() wrappers do.
To help us ensure correctness (from this POV), we have a
syntax-check rule that forbids any occurrence of
"virSecurityManager" string under src/qemu/ (except for
qemu_security of course).
But with if we want to remove virSecurityManagerPtr type, then we
have to allow "virSecurityManager *". Therefore, change the rule
so that no call of a function with "virSecurityManager" prefix is
allowed. And also change the name to better reflect what is going

Trying to report an OOM error is pointless since our infrastructure to
report error needs to allocate memory to report the error.
In addition our code mistakenly reported OOM errors even in cases where
a function could fail for another reason, which would make issues harder
to debug.
Remove the virReportOOMError and backend so that programmers are forced
to think about what can happen. In case when there's another failure
possible a specific error should be reported and otherwise a direct
abort() is better since the logger would abort on g_new anyways.
This patch also removes the syntas-check which forces use of
virReportOOMError instead of using VIR_ERR_NO_MEMORY with other
functions. This allows possible future use when we'd end up in a
situation where trying to recover from an OOM would make sense, such as
when attempting to allocate a massive buffer.

When accessing libvirtd over a SSH tunnel, the remote driver needs a way
to proxy the SSH input/output stream to a suitable libvirt daemon. This
is currently done by spawning netcat, pointing it to the libvirtd socket
path. This is problematic for a number of reasons:
- The socket path varies according to the --prefix chosen at build
time. The remote client is seeing the local prefix, but what we
need is the remote prefix
- The socket path varies according to remote env variables, such as
the XDG_RUNTIME_DIR location. Again we see the local XDG_RUNTIME_DIR
value, but what we need is the remote value (if any)
- The remote driver doesn't know whether it must connect to the legacy
libvirtd or the modular daemons, so must always assume legacy
libvirtd for back-compat. This means we'll always end up using the
virtproxyd daemon adding an extra hop in the RPC layer.
- We can not able to autospawn the libvirtd daemon for session mode
access
To address these problems this patch introduces the 'virtd-ssh-helper'
program which takes the URI for the remote driver as a CLI parameter.
It then figures out which daemon to connect to and its socket path,
using the same code that the remote driver client would on the remote
host's build of libvirt.
