Federico Ponzi 987e8489d0 aya-utils: add syscall_prefix and syscall_fnname_add_prefix 
These two functions are needed because kernel symbols representing
syscalls have architecture-specific prefixes.

These are the equivalent of bcc's get_syscall_fnname and
get_syscall_prefix.

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.

Alessandro Decina 93ac3e94bc aya: support relocations across multiple text sections + fixes

Alessandro Decina 401ea5e848 aya, aya-obj: refactor map relocations 
Clearly split the code between `.maps`, `maps` and data maps (bss, data,
rodata). Sprinkle comments.

Remove MapKind which was effectively only needed since we used to have
one variant - BpfSectionKind::Data - to represent all data maps. Instead
add explicit BpfSectionKind::{Data, Rodata, Bss} variants and match on
those when we initialize maps.

Dave Tucker a18693b42d aya: Add support for multibuffer programs 
This adds support for loading XDP programs that are multi-buffer
capable, which is signalled using the xdp.frags section name. When this
is set, we should set the BPF_F_XDP_HAS_FRAGS flag when loading the
program into the kernel.

Dave Tucker 7a720ab0c1 aya: Add from_pin for Programs 
This commit adds from_pin() which allows the creation of a Program
from a path on bpffs. This is useful to be able to call `attach` or
other APIs for programs that are already loaded to the kernel.

This differs from #444 since it implements this on the concrete program
type, not the Program enum, allowing the user to pass in any additional
context that isn't available from bpf_prog_info.
