Sven Cowart d1019413dd doc(aya): document tcx link pinning for atomic program replacement 
Add documentation and integration test for SchedClassifier link pinning,
which enables zero-downtime program updates in production environments.

- Add link pinning example to SchedClassifier::attach_with_options()
  showing atomic replacement workflow for TCX mode (kernel >= 6.6).
- Add pin_tcx_link() integration test verifying link persistence
  across program unload and atomic replacement capability.

perf_event: support hardware breakpoints 
Implement `PerfEventConfig::Breakpoint`, allowing users to attach
hardware breakpoints. Generate `HW_BREAKPOINT_*` and `struct
bpf_perf_event_data` in support of this feature and update the type of
`PerfEventContext` accordingly.

Add a test exercising R, W, RW, and X breakpoints. Note that R
breakpoints are unsupported on x86, and this is asserted in the test.

Extend the VM integration test harness and supporting infrastructure
(e.g. `download_kernel_images.sh`) to download kernel debug packages and
mount `System.map` in initramfs. This is needed (at least) on the aarch
6.1 Debian kernel which was not compiled with `CONFIG_KALLSYMS_ALL=y`
for some reason, and the locations of globals are not available in
kallsyms. To attach breakpoints to these symbols in the test pipeline,
we need to read them from System.map and apply the KASLR offset to get
their real address. The `System.map` file is not provided in the kernel
package by default, so we need to extract it from the corresponding
debug package. The KASLR offset is computed using `gunzip` which appears
in kallsyms on all Debian kernels tested.

aya-ebpf: reduce repetition and excessive traits 
The traits `FromBtfArgument`, `FromRawTracepointArgs`, `FromPtRegs` are
all fancy ways of saying `Argument` - so replace these traits with it.

This also removes the use of `bpf_probe_read` which was introduced in
05c1586202 because I can't reproduce the
need for it.

Andrew Werner 03e8487177 aya: rename `set_` methods on `EbpfLoader` 
This loader is more of a builder, so these `set_` methods didn't
quite fit. See [this discussion][1] for the motivation.

Andrew Werner 17171647f7 aya/maps/ring_buf: fix producer position initialization 
The RingBuf caches the last value it read of the producer so it doesn't
need to constantly contend on the actual producer cache line if lots of
messages have yet to be consumed. It was bogus to initialize this cache
at 0. This patch initializes it properly and adds testing.

Fixes: #1309

xtask: copy kernel config into the initramfs image 
When preparing the VM initramfs detect the `config-*` file that ships alongside
the vmlinuz/modules in each kernel archive and install it under `/boot` (both
as `/boot/config` and `/boot/config-<version>`). This makes the running
kernel’s configuration available inside the guest for the integration tests.

Michal R 0b2a544ddd aya-ebpf: Add BTF array definition 
Before this change, Aya supported only legacy BPF map definitions, which
are instances of the `bpf_map_def` struct and end up in the `maps` ELF
section.

This change introduces a BTF map definition for arrays, with custom
structs indicating the metadata of the map, which end up in the `.maps`
section.

Adam Schreck 263e864cd9 aya: add Map::from_map_data() for pinned map access 
Enables creation of Map enum variants directly from MapData instances,
allowing user-space handles to pinned BPF maps without requiring the
original BPF object.

Supports multiple BPF map types.

Motivation:
- Simplifies accessing pinned maps from user space applications.
- Avoids full BPF reloads and potential deadlocks.
- Matches existing ergonomic APIs like LruHashMap::try_from.
- Keeps user code safe and idiomatic.

Closes https://github.com/aya-rs/aya/issues/1305.

Includes test coverage to validate the new API.
