c10185837c Fix the conversion macro for .note sections, broken in the case
the ELF file's byte order is not the native byte order.  The
bug is that the variables holding the name and description size
are used (natively) after having been byte-swapped.  The fix is
to calculate sz from them just prior to byte-swapping.

5da7d44acb GCC for PowerPC does not align .note sections to 4 bytes. When
running ctfmerge on its objects, libelf asserts as it expects
.note sections to be 4-byte aligned.  Change that expectation.

bc5fce8d8f * Allow API dwarf_loclist_n() and dwarf_loclist() to be called with
attributes that have form DW_FORM_sec_offset.
* If the .debug_info section conforms to DWARF4, do not allow the value
  of attributes with form DW_FORM_data[48] to be used as section
  offset.

255d921adc Add a sanity check: The provided offset for the desired location list
should not exceed the size of the .debug_loc section.

9c016dc4b2 API dwarf_attrval_flag() should properly handle an attribute with
(DWARF4) form DW_FORM_flag_present which implicitly indicates the
presence of the attribute. Manual page is updated to reflect this
change.

Note that this was previously fixed in the old libdwarf.

1201c6fd27 Fix typo: the public API dwarf_child() should return DW_DLV_NO_ENTRY
instead of DW_DLE_NO_ENTRY when a child DIE is not found.

4e5c697507 Use FreeBSD's ELF headers instead of the elfdefinitions.h header which
comes with elftoolchain. This version of libelf doesn't need to be
portable; using FreeBSD's own ELF headers will avoid conflicts and
make integration easier.
