Dave Tucker 5726b6d044 aya: Allow pin to be used on all programs 
This allows for `pin` to be called as `Xdp::pin()` or
Program::pin() - the same way that unload() can be used.
This simplifies the use of this API.

Michal Rostecki bebe98e670 aya: Raise the warning when RMILIT_MEMLOCK is not RLIM_INFINITY 
Kernels before 5.11 don't use cgroup accounting, so they might reach the
RLIMIT_MEMLOCK when creating maps. After this change, we raise a warning
recommending to raise the RLIMIT_MEMLOCK.

Dave Tucker b4413322e3 aya: Replace ProgramFd trait with struct 
This removes the ProgramFd trait with a struct that wraps a RawFd.
Program::fd() has been implemented as well as fd() for each Program
Type. This allows for a better API than requiring the use of the
ProgramFd trait.

Alessandro Decina cb57d10d25 aya: rework links 
Remove LinkRef and remove the Rc<RefCell<_>> that was used to store
type-erased link values in ProgramData. Among other things, this allows
`Bpf` to be `Send`, which makes it easier to use it with async runtimes.

Change the link API to:

    let link_id = prog.attach(...)?;
    ...
    prog.detach(link_id)?;

Link ids are strongly typed, so it's impossible to eg:

    let link_id = uprobe.attach(...)?;
    xdp.detach(link_id);

As it would result in a compile time error.

Links are still stored inside ProgramData, and unless detached
explicitly, they are automatically detached when the parent program gets
dropped.

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

Michal Rostecki 7e2fcd1d6d Support for fentry and fexit programs 
fentry and fexit programs are similar to kprobe and kretprobe, but they
are newer and they have practically zero overhead to call before or
after kernel function. Also, fexit programs are focused on access to
arguments rather than the return value.

Those kind of programs were introduced in the following patchset:

Use current kernel version as default if not specified 
When a BPF program doesn't specify the target kernel version, the
most compatible option is to set the program kernel version to match
the currently running kernel.

aya/aya-bpf: implement btf tracepoint programs 4 years ago
William Findlay 169478c863 Add support for raw tracepoint and LSM programs 
This change adds support for the following program types:

* raw tracepoint
* LSM

Supporting LSM programs involved a necessity of supporting more
load_attrs for the BPF_PROG_LOAD operation, concretely:

* expected_attach_type - for LSM programs, it has always to be set to
  BPF_LSM_MAC
* attach_btf_obj_fd - it's often used to reference the file descriptor of
  program's BTF info, altough in case of LSM programs, it only has to
  contain the value 0, which means the vmlinux object file (usually
  /sys/kernel/btf/vmlinux)
* attach_btf_id - ID of the BTF object, which in case of LSM programs is
  the ID of the function (the LSM hook)

The example of LSM program using that functionality can be found here:

https://github.com/vadorovsky/aya-example-lsm

Dave Tucker 9426f36f79 Implement Pinning For Programs and Maps 
This commit adds 2 new methods to aya::sys
- bpf_pin_object
- bpf_get_object

Which allow the pinning and retrieval of programs/maps to bpffs.

It adds a `Program.pin` API, such that a loaded program can be pinned.
For map pinning, the user must ensure the `pinning u32` in the
`bpf_map_def` is set to 1, maps will be pinned using a new builder API.

BpfLoader::new().map_pin_path("/sys/fs/bpf/myapp").load_file("myapp.o")

This will pin all maps whose definition requests pinning to path + name.
