[libvirt] [PATCH] qemu: Fix escape_monitor(escape_shell(command))

Suspending a VM which contains shell meta characters doesn't work with libvirt-0.8.7: /var/log/libvirt/qemu/andreas_231-ne\ doch\ nicht.log: sh: -c: line 0: syntax error near unexpected token `doch' sh: -c: line 0: `cat | { dd bs=4096 seek=1 if=/dev/null && dd bs=1048576; } Although target="andreas_231-ne doch nicht" contains shell meta characters (here: blanks), they are not properly escaped by src/qemu/qemu_monitor_{json,text}.c#qemuMonitor{JSON,Text}MigrateToFile() First, the filename needs to be properly escaped for the shell, than this command line has to be properly escaped for qemu again. For this to work, remove the old qemuMonitorEscapeArg() wrapper, rename qemuMonitorEscape() to it removing the handling for shell=TRUE, and implement a new qemuMonitorEscapeShell() returning strings using single quotes. Using double quotes or escaping special shell characters with backslashes would also be possible, but the set of special characters heavily depends on the concrete shell (dsh, bash, zsh) and its setting (history expansion, interactive use, ...)
