11:50 a.m.
Add new function to manage adding the -fsdev options to the
command line removing that task from the mainline qemuBuildCommandLine.
Since both qemuBuildFSStr and qemuBuildFSDevStr are local, make them
static and fix their prototypes to use the const virDomainDef as well.
Make some minor formatting changes for long lines.
