in db_sym.[ch] as it is used by the elf version of crash(8).
i will be cleaning up the db_sym.c code in a follow up commit to avoid
having dead code compiled.
ddb running on crash dumps, but with two notable changes:
- Breakpoints, watches, etc are obviously never going to work so they
are not handled.
- You can pipe output to the shell, e.g. ps | grep foo
Items remaining to be done:
- Port it to architectures other than i386. This isn't difficult, just
a case of making db_disasm.c/db_trace.c or their equivalent compile
and work.
- Make more of the "show" commands work, e.g "show uvmexp".
