Shenghui Ye 772af170ae aya-obj: add documentation on program names
This commit adds documentation on how program names are parsed from
section names, as is used by `aya_obj::Object.programs` as HashMap keys,
and updates the examples into using program names.

Shenghui Ye 30f1fabc05 aya-obj: add no_std feature
The crate has few libstd dependencies. Since it should be platform-
independent in principle, making it no_std like the object crate would
seem reasonable.

However, the feature `error_in_core` is not yet stabilized, and the
thiserror crate currently offers no no_std support. When the feature
no_std is selected, we enable the `error_in_core` feature, switch to
thiserror-core and replace the HashMap with the one in hashbrown.

Shenghui Ye ac49827e20 aya-obj: migrate aya::obj into a separate crate
To split the crate into two, several changes were made:
1. Most `pub(crate)` are now `pub` to allow access from Aya;
2. Parts of BpfError are merged into, for example, RelocationError;
3. BTF part of Features is moved into the new crate;
4. `#![deny(missing_docs)]` is removed temporarily;
5. Some other code gets moved into the new crate, mainly:
   - aya::{bpf_map_def, BtfMapDef, PinningType},
   - aya::programs::{CgroupSock*AttachType},

The new crate is currenly allowing missing_docs. Member visibility
will be adjusted later to minimize exposure of implementation details.

Shenghui Ye 81bc307dce aya-obj: migrate bindgen destination
Aya::obj depends on bindgen generated files, and we start
by migrating bindgen generated files.

This commit adds the new aya-obj crate to the workplace
and migrates generated files into the crate. We use core
instead of std in an effort to make the final crate no_std.

Bindgen was run against libbpf v1.0.1.

Tuetuopay 890e8c9340 bpf: fix set_mark by not copying __sk_buff
Such an assignment in two parts (first deref in `unsafe`, then field
access outside of `unsafe`) is bogus: the deref "returned" by the
`unsafe` block actually creates a copy of the `__sk_buff` struct because
it implements `Copy`. The mark value is written to the `mark` field of
the copy, and not the real `__sk_buff`.

Change it to do it all in the `unsafe` block.

The same is done for the `.len()` getter to avoid copying the whole
`__sk_buff` struct for a 32 bit field. Although such a copy should be
optimized out by the compiler, it's better to help it do so.

Milan 8f1163a400 Add support for BPF_PROG_TYPE_CGROUP_DEVICE
Kernel 4.15 added a new eBPF program that can
be used with cgroup v2 to control & observe device
access (e.g. read, write, mknod) - `BPF_PROG_TYPE_CGROUP_DEVICE`.

We add the ability to create these programs with the `cgroup_device`
proc macro which creates the `cgroup/dev` link section. Device
details are available to the eBPF program in `DeviceContext`.

The userspace representation is provided with the `CgroupDevice`
structure.

Fixes: #212
