To avoid the need for duplicating implementations of virStream drivers, provide a generic implementation that can handle any FD based stream. This code is copied from the existing impl in the QEMU driver, with the locking moved into the stream impl, and addition of a read callback The FD stream code will refuse to operate on regular files or block devices, since those can't report EAGAIN properly when they would block on I/O * include/libvirt/virterror.h, include/libvirt/virterror.h: Add VIR_FROM_STREAM error domain * src/qemu/qemu_driver.c: Remove code obsoleted by the new generic streams driver. * src/fdstream.h, src/fdstream.c, src/fdstream.c, src/libvirt_private.syms: Generic reusable FD based streams
