This fixes two strip(1) issues found during ports exp-run and adds a
string hash implementation which significantly speeds up certain

This also improves libdwarf handling for stripped objects with
.eh_frame or .debug_frame (but not other debug) sections.

This includes a number of libdwarf improvements (particularly DWARF4
related) and updates to elftoolchain tools such as strip(1). It also
includes a large number of miscellaneous fixes (memory leaks, sign and
cast warnings, integer overflow and underflow, etc.).
This is a merge of r276167,276170-276172 from the

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.
(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.
