Use a temporary variable 'newconn' to hold the newly opened connection
until we are ready to pass it back instead of the original connection.
This way we can avoid complicated 'error'/'cleanup' sections.

Refactor the code to use virTypedParamList which simplifies cleanup.

The 'identparams' typed parameter list obtained from
virIdentityGetParameters is leaked when called from
'virGetConnectGeneric'.
Use 'virTypedParamListFromParams' to absorb it into a virTypedParamList
which can be autofreed.
Note that the memleak is observable only when running in split-daemon
mode.

Similarly to the qemu driver if we store the immutable driver pointer in
the VM private data struct we don't have to questionably pass it through
opaque pointers to callbacks.

When dealing with fdsets only we don't need to pass the FD first as we

Unix socket chardevs with FD passing need to use the direct mode so we

Originally I envisioned a common set of APIs for both FD passing
approaches but it turns out they are not really compatible enough for it
to make sense to use one set of APIs.
As of such introduce a distinct set of APIs for the 'direct' mode, which
will later be used to convert all places that currently use
'qemuFDPassNewDirect' and later clean up the existing APIs.

Now that we store the state of the host FIPS mode setting in the qemu
driver object, we don't need to outsource the logic into
'qemuCheckFips'.
Additionally since we no longer support very old qemu's which would not
yet have --enable-fips we can drop the part of the comment about very
old qemus.
