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.

Consider exec and exit events an end of outstanding calls
- This cleans up a lot of stuff. The actual substance is addition of
account_current_callstack in handle_event.c (which however uses
those cleaned-up interfaces).
- trace-exec.exp was extended to check that the exec syscall can be
seen in -c output. That's one of the symptoms of what this fixes.
- This hides dict_opt_c in summary.c. It also gets rid of the global
variable current_time_spent--instead, the information is passed via
a function argument in a struct timedelta (so that we never confuse
absolute time with relative). callstack_element.time_spent was renamed
to .enter_time, as that is what it has always been.

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.

Drop return_addr from struct process
- The only interesting use seems to be in output.c, but there we assume
we are working with top-of-callstack anyway, and store fetch context
there, so we can simply fetch the return address this way as well.

Fix tracing Thumb mode on ARM
- Drop what amounts to global variable thumb_mode from struct process
- Thumb mode is encoded to address. That means that the code in
callstack_push_symfunc and insert_breakpoint has to assume that
what comes from get_return_address is mangled, and needs to go
through creating the breakpoint and then looking at its address.
That's awkward, and we should come up with a better API.

Add proc_find_symbol, use it to find corresponding symbols for clones
The code in breakpoint_clone was buggy--it looked through old_proc's
symbols. It was also needlessly verbose, proc_find_symbol uses library
key to find the right library. Instead use the new interface and call
it on new_proc to find the new symbol.
We also didn't relink symbols in stack elements of a cloned process in
process_clone. Use proc_find_symbol for this as well.

Neither latent, nor delayed symbols are given a breakpoint. The difference
is in who's responsible for the state. Latent symbols are (will be) used
by ltrace core. Delayed symbols are used by backends. Only when both of
these flags are cleared is a breakpoint enabled for the symbol.

Track elf class in struct Process
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.

Add expr.c, expr.h, plug in properly
- in callstack_pop, we don't free arch_ptr. That's because this doesn't
get copied over the clone. It's a mere coincidence that fork() doesn't
need to save register arguments, and this works.
- added copyright notices to files that this touches. This is based on
git blame. Only contributors of 10+ lines are added
- test suite adjusted to not include "void" type as "don't show this int".
Back ends in general need to know the exact type, so this never worked
anyway.
