```
debug: support loading elf debug info from external files

Some distributions (ie. Ubuntu) have their libc debug
info in separate files. This change allows the stack walking
code to read that debug info.

- add support for reading compressed ELF sections
- support reading the build-id from the elf headers in order to lookup external debug info
- support reading the .gnu_debuglink section to look up external debug info

```
