[PATCH 17/24] qemu: Store TLS config options for chardevs in qemuDomainChrSourcePrivate

[Peter Krempa <pkrempa@xxxxxxxxxx>]

When setting up TLS options from config in qemuDomainPrepareChardevSourceOne
we can also extract the x509 certificate path and default tlsVerify
setting so that 'qemuBuildChardevCommand' doesn't need to access the
config object any more.
