Test elfutils output of a mixed core note.
This is a test for previous commit. The core file was snipped so that only
headers and note contents are left. NT_ARM_VFP is the note that exercises
the code.

In mixed core notes, don't let handle_core_item repeat.
If a core note contains both registers and items, descsz is 0 to express
that we don't wish to repeat the items. If there is only one item in
such note, a special block of code hits that passes &size to
handle_core_item, which will decrease that size by the amount consumed by
the item. But because size is 0, it underflows and wraps, and the loop
following this block, which handles the common case, overruns the core
note buffer.

readelf and tests were using hard coded string tables to produce DWARF

DWZ multifile forms http://www.dwarfstd.org/ShowIssue.php?issue=120604.1
DW_FORM_GNU_ref_alt and DW_FORM_GNU_strp_alt reference an alternative
debuginfo file. dwarf_begin and dwarf_begin_elf will try to use this
automatically. There are no user visible changes to the libdw interface.
dwarf_formref_die, dwarf_formstring and dwarf_formudata can now return
a Dwarf_Die which comes from a CU in the alternative Dwarf descriptor.
__libdw_read_offset was adjusted to take an alternative Dwarf descriptor
into account.
