Fix rustup command in the docs. () 
rustup install nightly --component rust-src

gives:

```
error: Found argument '--component' which wasn't expected, or isn't valid in this context

USAGE:
    rustup install [FLAGS] [OPTIONS] <toolchain>...

For more information try --help
```

The correct command seems to be `rustup toolchain install nightly --component rust-src`.

Alessandro Decina c2a90c2c01 aya: tc: add qdisc_detach_program 
qdisc_detach_program can be used to detach all the programs that have
the given name. It's useful when you want to detach programs that were
attached by some other process (eg. iproute2), or when you want to
detach programs that were previously left attached because the program
that attached them was killed.

Merge pull request from tw4452852/minor_fix_for_stackid 
bpf: fix a minor bug due to stackid allocation
Tw d1b7b024dc bpf: fix a minor bug due to stackid allocation 
The type casting introduces an allocation, this will cause compiling failure when linking final bpf target.
So remove this casting to fix this issue.

BTW, the following is the failure I met:

= note: 07:24:12 [ERROR] fatal error: "unable to allocate function return #1"
          PLEASE submit a bug report to https://bugs.llvm.org/ and include the crash backtrace.
          Stack dump:
          0.    Running pass 'Function Pass Manager' on module 'trace_bpf-001a275b17e9eb12'.
          1.    Running pass 'BPF DAG->DAG Pattern Instruction Selection' on function '@_ZN7aya_bpf4maps11stack_trace10StackTrace11get_stackid17h32b649bc3780c0aaE'

aya: support both bpf_map_def layout variants 
Libbpf and iproute2 use two slightly different `bpf_map_def` layouts. This change implements support for loading both.
