Add the library entry point for the new virDomainQemuMonitorCommand() entry point. Because this is not part of the "normal" libvirt API, it gets its own header file, library file, and will eventually get its own over-the-wire protocol later in the series. Changes since v1: - Go back to using the virDriver table for qemuDomainMonitorCommand, due to linking issues - Added versioning information to the libvirt-qemu.so Changes since v2: - None Changes since v3: - Add LGPL header to libvirt-qemu.c - Make virLibConnError and virLibDomainError macros instead of function calls Changes since v4: - Move exported symbols to libvirt_qemu.syms Signed-off-by: Chris Lalancette <clalance@redhat.com>
