Tamir Duberstein c139627f8f aya-obj: reduce indirection in section parsing
Remove repetition of permitted cgroup attach types. Make optionality of
name more explicit rather than pretending both kind and name are equal
to section.

aya: flip feature "no_std" to feature "std"
This fixes `cargo build --all-features` by sidestepping the feature
unification problem described in The Cargo Book[0].

Add `cargo hack --feature-powerset` to CI to enforce that this doesn't
regress (and that all combinations of features work).

Since error_in_core is nightly-only, use core-error and a fake std
module to allow aya-obj to build without std on stable.

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 e52497cb9c aya-obj: add basic documentation to public members
Types relevant to maps are moved into aya_obj::maps.
Some members are marked `pub(crate)` again.

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.
