libdw: Don't leak duplicate FDEs.
Although it isn't supposed to happen there could be FDEs that cover the
same address range. Don't leak such FDEs and use an existing FDE for
consistency.

libdw: Don't use a FDE if it doesn't actually cover a real code range.
If the FDE end <= start then it doesn't actually cover a valid code range.
Don't use and cache such FDEs (it will cause memory leaks if there is
another FDE that has the same start address and a valid code range).
Such FDEs have been seen in the backtrace.ppc.exec testfile.

libdw: Robustify eh_frame_hdr and encoded-values reading.
Sanity check and keep track of binary_search_table data buffer length.
Add bounds check to encoded value reading. Also fix a bug when reading
the eh_frame header data from an other endian ELF image. Add a testcase
that would fail the new sanity checks because of the endian bug.

libdw: Add get_uleb128 and get_sleb128 bounds checking.
Both get_uleb128 and get_sleb128 now take an end pointer to prevent
reading too much data. Adjust all callers to provide the end pointer.
There are still two exceptions. "Raw" dwarf_getabbrevattr and
read_encoded_valued don't have a end pointer associated yet.
They will have to be provided in the future.
