libbpf: Fix various errors and warning reported by checkpatch.pl Fix a bunch of warnings and errors reported by checkpatch.pl, to make it easier to spot new problems.

This is a mirror of bpf-next linux tree's tools/lib/bpf directory plus its supporting header files.
The following files will by sync'ed with bpf-next repo:
src/ <-> bpf-next/tools/lib/bpf/include/uapi/linux/bpf_common.h <-> bpf-next/tools/include/uapi/linux/bpf_common.hinclude/uapi/linux/bpf.h <-> bpf-next/tools/include/uapi/linux/bpf.hinclude/uapi/linux/btf.h <-> bpf-next/tools/include/uapi/linux/btf.hinclude/uapi/linux/if_link.h <-> bpf-next/tools/include/uapi/linux/if_link.hinclude/uapi/linux/if_xdp.h <-> bpf-next/tools/include/uapi/linux/if_xdp.hinclude/uapi/linux/netlink.h <-> bpf-next/tools/include/uapi/linux/netlink.hinclude/tools/libc_compat.h <-> bpf-next/tools/include/tools/libc_compat.hOther header files at this repo (include/linux/*.h) are reduced versions of their counterpart files at bpf-next's tools/include/linux/*.h to make compilation successful.
libelf is an internal dependency of libbpf and thus it is required to link against and must be installed on the system for applications to work. pkg-config is used by default to find libelf, and the program called can be overridden with PKG_CONFIG. If using pkg-config at build time is not desired, it can be disabled by setting NO_PKG_CONFIG=1 when calling make.
To build both static libbpf.a and shared libbpf.so:
$ cd src
$ make
To build only static libbpf.a library in directory build/ and install them together with libbpf headers in a staging directory root/:
$ cd src $ mkdir build root $ BUILD_STATIC_ONLY=y OBJDIR=build DESTDIR=root make install
To build both static libbpf.a and shared libbpf.so against a custom libelf dependency installed in /build/root/ and install them together with libbpf headers in a build directory /build/root/:
$ cd src $ PKG_CONFIG_PATH=/build/root/lib64/pkgconfig DESTDIR=/build/root make install
