Dave Tucker bf7fdff1ce aya: Find programs using the symbol table 
This makes a few changes to the way that Aya reads the ELF object
files.

1. To find programs in a section, we use the symbols table. This allows
   for cases where multiple programs could appear in the same section.
2. When parsing our ELF file we build symbols_by_section_index as an
   optimization as we use it for legacy maps, BTF maps and now programs.

As a result of theses changes the "NAME" used in `bpf.prog_mut("NAME")`
is now ALWAYS the same as the function name in the eBPF code, making the
user experience more consistent.

Do not escape newlines on Err(LoadError).unwrap() 
Wrap verifier logs in a newtype whose `Debug` impl emits unescaped
newlines. This improves ergonomics in tests where we `Result::unwrap()`
those load errors; when these fail today they emit the errors with
newlines escaped, making them incredibly difficult to read.
Dave Tucker f833f1fc1d xtask: Add cargo-public-api 
Adds cargo-public-api. This allows for public API changes to get caught
in CI, requiring new changes to be "blessed" by using:

  cargo xtask public-api --bless

When this file is changed for aya, Alessandro will need to review the PR.
