libdw: Undefined behavior in get_sleb128_step.
gcc -fsanitize=undefined pointed out that for too big sleb128 values we
could shift into the sign bit. So for sleb128 values that have to fit
in a (signed) int64_t variable reduce the max number of steps by one.

libdw: Unroll the first get_sleb128 step to help the compiler optimize.
The common case is a single-byte. So no extra (max len) calculation is
necessary then.

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.

Rename read_ubyte_unaligned_inc to read_addr_unaligned_inc
- The behavior of this function has been changed to read only
address-sized quantities, i.e. the size of 2 is no longer allowed.
(Size of 1 never was.) The two outstanding uses, both in readelf.c,
which actually do use this call to read address-sized units, were
updated, rejecting fields that indicate weird address sizes.
- The three related calls, read_sbyte_unaligned_inc,
read_ubyte_unaligned and read_sbyte_unaligned were dropped. There
are currently no uses for these calls.

libdw (get_sleb128_step): Remove undefined behavior.
As pointed out by gcc -fsanitize=undefined left shifting a negative value
is undefined. Replace it with a multiplication of the signed value as
suggested by Richard Henderson and Josh Stone.

libdw: Simplify and inline get_uleb128 and get_sleb128
This removes the IS_LIBDW distinction so LEB128 operations are now
always inlined, and the implementations are simplified, more direct.
