This new API will allocate the secret, assign the def pointer, and
insert the secret onto the passed list. Whether that's the temporary
list in loadSecrets which gets loaded into the driver list or driver
list during secretDefineXML.

Add a temporary helper to search for a specific secret by address
on the list and remove it if it's found. The following patch will
introduce a common allocation and listInsert helper. That means
error paths of the routines calling would need a way to remove the
secret off the list.

This patch removes need for secretBase64Path and secretComputePath. Similar
to the configFile, create an entry for base64File, which will be generated
as the driver->configDir, the UUID value, plus the ".base" suffix. Rather
than generating on the fly, store this in the virSecretObj.

The buildup of the pathname done in loadSecrets where the failure to build
is ignored which is no different than the failure to generate the name
in secretLoadValue which would have been ignored in the failure path
after secretLoad.

This also removes the need for secretComputPath and secretBase64Path.

This patch removes the need for secretXMLPath. Instead save 'path' during
loadSecret as 'configFile'. The secretXMLPath is nothing more than an
open coded virFileBuildPath.  All that code did was concantenate the
driver->configDir, the UUID of the secret, and the ".xml" suffix to form
the configFile name which we now will generate and save instead.

The 'secretLoad' was essentially open coding virFileBuildPath.

Adjust the logic to have the caller build the path and pass it. The net
sum of ignoring the virFileBuildPath failure is the same as before where
the failure to virAsprintf the path would have been ignored anyway in
the secretLoad error path.

Rather than having it interspersed with other changes, do it once.

Remove a couple ^L, 1 argument per line for functions, less than 80 chars

when no cleanup to be done.

For stateless, client side drivers, it is never correct to
probe for secondary drivers. It is only ever appropriate to
use the secondary driver that is associated with the
hypervisor in question. As a result the ESX & HyperV drivers
have both been forced to do hacks where they register no-op
drivers for the ones they don't implement.

For stateful, server side drivers, we always just want to
use the same built-in shared driver. The exception is
virtualbox which is really a stateless driver and so wants
to use its own server side secondary drivers. To deal with
this virtualbox has to be built as 3 separate loadable
modules to allow registration to work in the right order.

This can all be simplified by introducing a new struct
recording the precise set of secondary drivers each
hypervisor driver wants

struct _virConnectDriver {
    virHypervisorDriverPtr hypervisorDriver;
    virInterfaceDriverPtr interfaceDriver;
    virNetworkDriverPtr networkDriver;
    virNodeDeviceDriverPtr nodeDeviceDriver;
    virNWFilterDriverPtr nwfilterDriver;
    virSecretDriverPtr secretDriver;
    virStorageDriverPtr storageDriver;
};

Instead of registering the hypervisor driver, we now
just register a virConnectDriver instead. This allows
us to remove all probing of secondary drivers. Once we
have chosen the primary driver, we immediately know the
correct secondary drivers to use.

The secret driver can rely on its global state instead
of the connect private data.

Since virSecretFree will call virObjectUnref anyway, let's just use that
directly so as to avoid the possibility that we inadvertently clear out
a pending error message when using the public API.

Convert all remaining clients of readdir to use the new
interface, so that we can ensure (unlikely) errors while
reading a directory are reported.

* src/openvz/openvz_conf.c (openvzAssignUUIDs): Use new
interface.
* src/parallels/parallels_storage.c (parallelsFindVolumes)
(parallelsFindVmVolumes): Report readdir failures.
* src/qemu/qemu_driver.c (qemuDomainSnapshotLoad): Ignore readdir
failures.
* src/secret/secret_driver.c (loadSecrets): Likewise.
* src/qemu/qemu_hostdev.c
(qemuHostdevHostSupportsPassthroughVFIO): Report readdir failures.
* src/xen/xen_inotify.c (xenInotifyOpen): Likewise.

The source code base needs to be adapted as well. Some files
include virutil.h just for the string related functions (here,
the include is substituted to match the new file), some include
virutil.h without any need (here, the include is removed), and
some require both.

Ensure that all drivers implementing public APIs use a
naming convention for their implementation that matches
the public API name.

eg for the public API   virDomainCreate make sure QEMU
uses qemuDomainCreate and not qemuDomainStart

Currently to deal with auto-shutdown libvirtd must periodically
poll all stateful drivers. Thus sucks because it requires
acquiring both the driver lock and locks on every single virtual
machine. Instead pass in a "inhibit" callback to virStateInitialize
which drivers can invoke whenever they want to inhibit shutdown
due to existance of active VMs.

The virStateInitialize method and several cgroups methods were
using an 'int privileged' parameter or similar for dual-state
values. These are better represented with the bool type.

Commit cd1e8d1c assumed that systems new enough to have journald
also have mkostemp; but this is not true for uclibc.

For that matter, use of mkstemp[s] is unsafe in a multi-threaded

mkstemp and mkstemps.
