bpftools: add utility and library packages supporting eBPF usage Add support for building bpftool and libbpf from the latest 5.8.3 kernel sources, ensuring up-to-date functionality and fixes. Both are written to be backwards compatible, which simplfies build and usage across different OpenWRT image kernels. 'bpftool' is the primary userspace tool widely used for introspection and manipulation of eBPF programs and maps. Two variants are built: a 'full' version which supports object disassembly and depends on libbfd/libopcodes (total ~500KB); and a 'minimal' version without disassembly functions and dependencies. The default 'minimal' variant is otherwise fully functional, and both are compiled using LTO for further (~30KB) size reductions. 'libbpf' provides shared/static libraries and dev files needed for building userspace programs that perform eBPF interaction. Several cross-compilation and build-failure problems are addressed by new patches and ones backported from farther upstream: * 001-libbpf-ensure-no-local-symbols-counted-in-ABI-check.patch * 002-libbpf-fix-build-failure-from-uninitialized-variable.patch * 003-bpftool-allow-passing-BPFTOOL_VERSION-to-make.patch * 004-v5.9-bpftool-use-only-ftw-for-file-tree-parsing.patch Signed-off-by: Tony Ambardar <itugrok@yahoo.com>

bpftools: update, split off bpftool and libbpf packages My original bpftools package made "variant" builds of bpftool and libbpf as a convenience, since both used the same local kernel sources with the same versioning. This is no longer the case, since the commit below switched to using an out-of-tree build mirror hosting repos for each. Replace bpftools with separate bpftool and libbpf packages, each simplified and correctly versioned. Also fix the broken libbpf ABI introduced in the same commit. Existing build .config files are not impacted.
