Johannes Edmeier 2d79f22b40 aya-bpf: use bpf_read_probe for reading pt_regs 
Linux Kernels < 5.5 don't support bpf_probe_read_kernel. Therefore
bpf_probe_read must be used for compatibility reasons.

build(deps): update object requirement from 0.28 to 0.29

Michal Rostecki 78e58b8960 bpf(helpers): Add *_str_bytes helpers 
This change adds two new helpers:

* bpf_probe_read_user_str_bytes
* bpf_probe_read_kernel_str_bytes

Those new helpers are returning a bytes slice (`&[u8]`) with a length
equal to the length of probed, null-terminated string. When using those
helpers, users don't have to manually check for length and create such
slices themselves. They also make converting to `str` way more
convenient, for example:

```rust
let my_str = unsafe {
    core::str::from_utf8_unchecked(
        bpf_probe_read_user_str_bytes(user_ptr, &mut buf)?
    )
};
```

This change also deprecates the old helpers, since their names are
confusing (they have nothing to do with Rust `str`) and using them
requires writing boilerplate code (for checking the length and making
eBPF verifier happy):

* bpf_probe_read_user_str
* bpf_probe_read_kernel_str

Tested on:

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.

Andrew Burkett 36edf09254 Have bpf_map_update_elem take Option<&K> for key 
bpf_map_update_elem is used in lieu of bpf_map_push_elem to maintain support for kernel version < 4.20. The kernel expects a null pointer for the key for this use case. With this change, if you pass None as key to `bpf_map_update_elem`, it will pass null as key.

Tatsuyuki Ishi e852f7e0cc test: Update to use non-mut map types 2 years ago
Tatsuyuki Ishi 41c6b56142 bpf: Replace map types to use &self, remove HashMap::get_mut 
The bpf_map_defs are now wrapped with UnsafeCell, which also happens to
provide a cozy way to get a *mut pointer. An UnsafeCell isn't strictly
required as the struct fields are practically opaque to us, but using an
UnsafeCell follows the general best practices against miscompilation and
also prevents some obvious errors.

HashMap::get_mut was removed because the idea is completely unsound.
Previous users should wrap their data with UnsafeCell instead or use
atomics.
