[libvirt] [PATCH v4 0/4] qemu: Report better error on dump/migrate failure

Changes from [v3]: * Make sure errors from virFileWrapperFdClose() result in an overall failure being bubbled up; * don't call virReportError() unless the function is going to report the failure through its return code as well; * revert b0c3e931804a more thoroughly. Changes from [v2]: * Move error reporting from virFileWrapperFdFree() to virFileWrapperFdClose(). Changes from [v1]: * Use VIR_FREE() followed by VIR_ALLOC_N() instead of manually setting the last (and only) byte of the array returned by VIR_REALLOC_N() to zero.
