Add support for using elfutils as unwinder.
This adds support for using elfutils as unwinder with -w. Since elfutils
0.158 elfutils contains a simple unwinder interface that matches nicely
on the ltrace backtrace support.
The code reuses the libunwind infrastructure already in ltrace where
possible (by defining HAVE_UNWINDER which is 1 if either libunwind or
elfutils is used). It also reuses the ltrace proc_add_library callback
to keep track of the ELF files mapped for the unwinder.
The current implementation matches the output as if libunwind was used.
But elfutils can also provide some more information since it can lookup
the DWARF debuginfo. So if the source info of an address can be found
through elfutils the backtrace will also include this as an additional
output line per frame.

The same work needs to be done on attach as when _start is hit
- Extract the logic to a separate function, called from open_pid and
entry_breakpoint_on_hit.
- Since there is no other way to get on dyn_addr in open_pid anyway,
simply look for the main library, and read it there. That means we
don't need to track that information at entry_breakpoint anymore,
and we can get rid of struct entry_breakpoint.

Use CBS_STOP_IF instead of hand-coding the same
- In cb_breakpoint_for_symbol, we would need CBS_FAIL_IF. But
CBS_FAIL isn't properly handled anywhere. The iterator client user
must provide alternate means of signalling errors anyway (e.g. a
flag passed in data) anyway. So convert this to CBS_STOP_IF, the
caller already assumes all stops are failures.

it on new_proc to find the new symbol.

Technically only s390 needs this at the moment, but it seems general enough
that it should be alongside the e_machine flag. Eventually it is desirable
to replace both fields with either a backend-provided ABI enum, or with
an ABI object that would implement the interesting back end calls.

Drop process.fixed_libs, enable breakpoints right away
The theory behing fixed_libs was broken from the beginning, we can't tell
dlopened libraries from fixed ones when attaching. We also don't need to
wait for _start to enable breakpoints. We may need this on LS_TOPLT_POINT
architectures, but that was added for PPC, and PPC doesn't need it anymore.

Support tracing PPC32 processes with both BSS and secure PLTs

- all PLTs are LS_TOPLT_EXEC. The difference is in the way the PLT entry

Change iterators each_task, each_process, library_each_symbol
... now the restarts are supported by start_after instead of start.
Otherwise the restart scenario was something like:
for (it *sym = NULL; (sym = next(sym)) != NULL; )
if ((sym = sym->next) == NULL)
break;
which just seems too convoluted.

Fix serious race in attach to many-threaded process
- the gist is that tasks continue running while we attach, so more tasks
come into existence, or the ones that we didn't attach to yet disappear,
etc.
- besides, we really can't enable breakpoints before we are done attaching,
otherwise the still-running tasks risk running into them and dying of
SIGTRAP.
