* dwarf_error.c: Add DW_DLE_DW_DLE_ATTR_OUTSIDE_SECTION.
* libdwarf.h.in: Add DW_DLE_DW_DLE_ATTR_OUTSIDE_SECTION.
* dwarf_form.c(dwarf_formexprloc): Call the new function
_dwarf_reference_outside_section() as a check
for an exprloc with data that is outside the section it
belongs in. Ie, a bug somewhere. Return error
DW_DLE_DW_DLE_ATTR_OUTSIDE_SECTION if applicable.
* dwarf_frame2.c(read_encoded_ptr): Pass error down so we set
a complete Dwarf_Error record at the point of error.
Just three functions that could use this were changed.
* dwarf_leb.c(_dwarf_decode_u_leb128): Presented with bogus
leb values we stop scanning the leb number before
overrunning our value-output buffer (and dumping core).

all cases.

to check the pointer is valid.

DW_DLE_FAILSAFE_ERRVAL for the malloc-arena-exhausted
case. Now use that static instead of aborting.

Only one producer callback declaration exists now:
Dwarf_Callback_Func.

* dwarf_die_deliv.c,dwarf_query.c: Gets the version stamp passed to
_dwarf_get_size_of_val() so DW_FORM_ref_addr handled
correctly.

specification says (V3 and later continue to
be handled unchanged.).
* dwarf_util.c: Handle DW_FORM_ref_addr as the V2
specification says (V3 and later continue to
be handled unchanged.).
* dwarf_addr_finder.c: Removed a mistaken handling
of DW_FORM_ref_addr. No one should be using this
function's features though...

#if 0 code.

* libdwarf.h.in: Removed trailing whitespace.
2014-02-01 David Anderson
* dwarf_alloc.c: Instead of doing a long list of address compares,
use the hash 'tree' and tfind() to determine if we malloced
the space or simply took an address from .debug_info (
or other in-memory section) when
we returned a _dwarf_get_alloc() pointer to the user.
2014-01-31 David Anderson
* configure.in: The test to generate HAVE___UINT32_T_IN_SYS_TYPES_H

* dwarf_query.c: Removed an unused local variable.
