[libbacktrace] Return struct dwarf_data pointer from elf_add
Allow the caller of elf_add access to the struct dwarf_data pointer
corresponding to the added elf.
2019-01-17 Tom de Vries <tdevries@suse.de>
* internal.h (backtrace_dwarf_add): Add fileline_entry parameter.
* dwarf.c (backtrace_dwarf_add): Add and handle fileline_entry parameter.
* elf.c (elf_add): Add and handle fileline_entry parameter. Add
argument to backtrace_dwarf_add call.
(phdr_callback, backtrace_initialize): Add argument to elf_add calls.
* pecoff.c (coff_add): Add argument to backtrace_dwarf_add call.
* xcoff.c (xcoff_add): Same.
