Valgrind:
* binparser.c (bin_parser_free): Add this function
* elfparser.c (elf_parser_free): Call bin_parser_free()
* sysprof.c (compute_text_width, add_text): Plug leaks
* collector.c (add_trace_to_stash): Copy n_addresses to a stack
variable instead of reading it out of the mmap'ed area all the
time. (That way if there is an overrun, we won't write too much
into the address array).

* module/sysprof-module.h (struct SysprofStackTrace): Increase the
max number of addresses to 1021, reorganise SysprofMmapArea to
make the traces naturally page aligned.
* TODO: Update

Deal with address offsets. Address lookup is now:

- Then convert to an offset into the text segment
- Then add the load address of the text segment (found in the
debug binary)
- Then finally lookup the result in the symbol table.
