Michal Rostecki 34d74fcd3b bpf: sk_buff: Add get_socket_uid method to SkBuffContext
This change exposes the BPF helper bpf_socket_get_uid as a public method
of SkBuffContext, which allows to get the owner UID of the socket
associated to the sk_buff stored in the context.

Kenjiro Nakayama 9e41317ca6 Fix socket_filter section match
`BPF_PROG_TYPE_SOCKET_FILTER` program expands the sectionname's kind with `socket` not `socket_filter`.
So current eBPF program with socket filter always fails.

This patch fixes it.

Dave Tucker 5ee1321765 aya: Fix Loading from cgroup/skb sections
fa037a88e2 allowed for cgroup skb programs
that did not specify an attach direction to use the cgroup/skb section
name per the convention established in libbpf. It did not add the
necessary code to load programs from those sections which is added in
this commit

Dave Tucker 657fb44525 test: Add compile_c_ebpf to library
This allows for C code to be compiled and used in tests!
It does require libbpf on the host machine though...

Also moved removal of the `user` and `ebpf` dirs created by rust-script
into `lib.sh` and parameterized bits of the XDP smoke test for ease of
copying

Alessandro Decina 8202105b7d aya: relocate .text references
Handle relocations against .text symbols in all instructions not just
calls. Makes it so that let x = &some_function triggers linking of
some_function in the current program and handles the resulting
relocation accordingly.

Among other things, enables the use of bpf_for_each_map_elem.

Dave Tucker 825bb3ad20 btf: Replace / in DATASEC before load to kernel
This replaces the / character with a . which is allowed in the kernel

fix it up here as it's commonly used for Aya
