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.

meson: Drop the .fa library suffix The non-standard .fa library suffix breaks the link source de-duplication done by Meson so drop it. The lack of link source de-duplication causes AddressSanitizer to complain ODR violations, and makes GNU ld abort when combined with clang's LTO. Fortunately, the non-standard suffix is not necessary anymore for two reasons. First, the non-standard suffix was necessary for fork-fuzzing. Meson wraps all standard-suffixed libraries with --start-group and --end-group. This made a fork-fuzz.ld linker script wrapped as well and broke builds. Commit d2e6f9272d33 ("fuzz: remove fork-fuzzing scaffolding") dropped fork-fuzzing so we can now restore the standard suffix. Second, the libraries are not even built anymore, because it is possible to just use the object files directly via extract_all_objects(). The occurences of the suffix were detected and removed by performing a tree-wide search with 'fa' and .fa (note the quotes and dot).
