qemuProcessNew is one of the 4 public functions used to create and
manage a qemu process for QMP command exchanges outside of domain
operations.

Add descriptive comment block, Debug statement and make source
consistent with the cleanup / VIR_STEAL_PTR format used elsewhere.

No functional changes are made.
