libdw: Fix overflow in read_encoded_value for the DW_EH_PE_indirect case.
If we are going to dereference a pointer there should be at least enough
data to hold a pointer. Found by afl-fuzz.

libdw: ensure read_encoded_value's value is set
With CFLAGS='-Og -g', F21 gcc hits -Werror=maybe-uninitialized in
read_encoded_value at "*result += value". It's fine with -O2/-O0.
In particular it seems to care about the __libdw_cfi_read_address_inc
calls. By my inspection, the only way those don't set value are for
error cases, which will then return immediately. This patch just sets
value = 0 to begin with, so gcc is always convinced it's fine.

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.
