There's no real reason for qemuMigrationParamsEnableTLS to require the
callers to pass a valid virQEMUDriverConfigPtr, it can just call
virQEMUDriverGetConfig.

The function checks whether QEMU supports TLS migration and stores the
original value of tls-creds parameter to priv->migTLSAlias. This is no
longer needed because we already have the original value stored in
priv->migParams.

Restore the original values of all migration parameters we store in
qemuDomainJobObj instead of explicitly resting only a limited set of
them.
The result is not strictly equivalent to the previous code wrt reseting
TLS state because the previous code would only reset it if we changed it
before while the new code will reset it always if QEMU supports TLS
migration. This is not a problem for the parameters themselves, but it
can cause spurious errors about missing TLS objects being logged at the
end of non-TLS migration. This issue will be fixed ~50 patches later.

Any job which touches migration parameters will first store their
original values (i.e., QEMU defaults) to qemuDomainJobObj to make it
easier to reset them back once the job finishes.

When connection to the client which controls a non-p2p migration gets
closed between Perform and Confirm phase, we don't know whether the
domain was successfully migrated or not. Thus, we have to leave the
domain paused and just cleanup the migration job and reset migration
parameters.
Previously we didn't reset the parameters and future save or snapshot
operations would see wrong environment (and could fail because of it) in
case the domain stayed running on the source host.

Currently migration parameters are stored in a structure which mimics
the QEMU migration parameters handled by query-migrate-parameters and
migrate-set-parameters. The new structure will become a libvirt's
abstraction on top of QEMU migration parameters, capabilities, and
related stuff.

It provides just another view on some migration parameters so let's move
it close to them. The end goal is to merge compression parameters with
the rest of migration parameters since it doesn't make any sense to
handle them differently.
