This commit adds QError support in the Monitor. A QError member is added to the Monitor struct. This new member stores error information and is also used to check if an error has occurred when the called handler returns. Additionally, a new macro called qemu_error_new() is introduced. It builds on top of the QemuErrorSink API and should be used in place of qemu_error(). When all conversion to qemu_error_new() is done, qemu_error() can be turned private. Basically, Monitor's error flow is something like this: 1. An error occurs in the handler, it calls qemu_error_new() 2. qemu_error_new() builds a new QError object and stores it in the Monitor struct 3. The handler returns 4. Top level Monitor code checks the Monitor struct and calls qerror_print() to print the error Signed-off-by: Luiz Capitulino <lcapitulino@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
