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
names. Not allowing a forward slash is perhaps a kernel bug, but lets
fix it up here as it's commonly used for Aya

only one pass over the BTF. This modifies the parsed BTF in place.

Dave Tucker 5d8b279265 aya: Fix BTF verifier output 
Currently errors can occur if the verifier output is > buffer as we get
ENOMEM. We should only provide a log_buf if initial load failed, then
retry up to 10 times to get full verifier output.

To DRY this logic it has been moved to a function so its shared with
program loading

Dave Tucker 686ce45f93 aya: Fix BTF type resolution for Arrays and Ints 
The union of `size` and `type` is unused in BTF_KIND_ARRAY.
Type information of elements is in the btf_array struct that follows in
the type_ field while the index type is in the index_type field.

For BTF_KIND_INT, only the offset should be compared and size and
signedness should be ignored.
