Merge pull request from astoycos/map_pin2 
aya: Implement dedicated map pinning
astoycos 82039144bd integration-test: Add map pinning coverage 
Add coverage to the new public api's for
map pinning (pin and unpin) which can be called
on the generic aya::Map type OR explit map types.

Additionally add coverage for the new libbpf
LIBBPF_PIN_BY_NAME behavior.

astoycos 7b71c7e1cd aya/maps: add pin() api 
- Adds new `maps_mut()` API to the BpfManager to allow us to iterate though
and pin all of maps at the same time.

- Adds new pin(Path)/unpin(Path) api to Maps so they
can be generically pinned AFTER load.

- Adds macro for pinning explicit map types in aya.
Convert all explicit map types "inner" field to be
pub crate in order to facilitate this.

astoycos 0bf97eba64 aya/maps: fix libbpf_pin_by_name 
Aligns with libbpf for the special LIBBPF_PIN_BY_NAME
map flag. Specifically if the flag is provided without a pin path
default to "/sys/fs/bpf".

Merge pull request from vadorovsky/deprecate-syscall-prefix 
util: Deprecate `syscall_prefix`
Mike Rostecki bd6ba3ad8b util: Deprecate `syscall_prefix` 
Using the prefix only for the host architecture is often not enough,
kernels usually provide symbols for more architectures, which are
used by multilib applications. Handling them might or might not be
necessary depending on the use case. Due to that complexity, we
decided to let the callers to handle prefixes the way they prefer.

integration/xdp: increase timeout to 60 seconds 
There's absolutely no reason to have a short timeout here. This has
resulted in at least one flake:

Merge pull request from ajwerner/deflake-loaded-at-take-2 
integration-test: deflake test_loaded_at
Andrew Werner da832e479d integration-test: deflake test_loaded_at 
The test could fail due to the lack of clock monotonicity. This PR
deflakes the test by adding retries.

xtask: terminate QEMU on "BUG: soft lockup" 
See
https://github.com/aya-rs/aya/actions/runs/6329828507/job/17190931752.

Unlike on kernel panic this message prints periodically so it is
permitted to print twice before QEMU is killed.

fix load time
astoycos dffff1ce6b integration-test: fix load time and add test 
Time since boot is defined as the UNIX_EPOCH plus the duration
since boot. which is realtime - boottime NOT boottime - realtime.

Add a integration test to ensure this doesn't happen again.

Tuetuopay 00dc7a5bd4 maps/xdp: make maps work on kernels not supporting ProgIds 
On startup, the kernel is probed for support of chained program ids for
CpuMap, DevMap and DevMapHash, and will patch maps at load time to have
the proper size. Then, at runtime, the support is checked and will error
out if a program id is passed when the kernel does not support it.
Tuetuopay 63ce2f013a bpf/devmap: don't expose `bpf_devmap_value` 
Use our own type that:
- is stable as not from bindgen
- does not have an union inside
Tuetuopay c6754c614e maps/xdp: use ProgramFd instead of impl AsRawFd 
Not having a generic here allows to pass `None` without specifying the
actual type you don't care about.
Tuetuopay 9ed1d3d281 bpf: add documentation for XDP maps
Tuetuopay db49633073 bpf: make xdp maps functions safe

reference to values.
Tuetuopay f7fbbcd0e5 aya: fix docstring missing trailing period
Tuetuopay 0647927e32 xdp: add support for chained xdp programs in {cpu,dev}map 
set/insert functions can now take an optional bpf program fd to run once
the packet has been redirected from the main probe
Tuetuopay 139f382638 aya: add support for map-bound XDP programs 
Such programs are to be bound to cpumap or devmap instead of the usual
network interfaces.
Tuetuopay 4452364c41 macros: add 'map' option to xdp macro 
This option allows to place the program in the specific sections to
chain programs with devmaps and cpumaps.
Tuetuopay ad3087d7eb bpf: Update XDP maps implementation 
The implementation changed since the original commit was written, and
some mistakes went in:
- missing bpf_redirect_map wrapper
- extra bpf_map_lookup_elem on maps for which it is forbidden
