block: move block exports to libblockdev Block exports are used by softmmu, qemu-storage-daemon, and qemu-nbd. They are not used by other programs and are not otherwise needed in libblock. Undo the recent move of blockdev-nbd.c from blockdev_ss into block_ss. Since bdrv_close_all() (libblock) calls blk_exp_close_all() (libblockdev) a stub function is required.. Make qemu-nbd.c use signal handling utility functions instead of duplicating the code. This helps because os-posix.c is in libblockdev and it depends on a qemu_system_killed() symbol that qemu-nbd.c lacks. Once we use the signal handling utility functions we also end up providing the necessary symbol.

configure: introduce --enable-vhost-user-blk-server Make it possible to compile out the vhost-user-blk server. It is enabled by default on Linux. Note that vhost-user-server.c depends on libvhost-user, which requires CONFIG_LINUX. The CONFIG_VHOST_USER dependency was erroneous since that option controls vhost-user frontends (previously known as "master") and not device backends (previously known as "slave").
