Handle the new DW_FORM_implicit_const. The value of this form is embedded
in the abbrev data (as sleb128) and not in the info DIE data. This also
adds a new function dwarf_getabbrevattr_data which allows getting any
data/value associated with a form. eu-readelf will use this new function
to show the DW_FORM_implicit_const value.

When creating a Dwarf_Abbrev in dwarf_getabbrev (__libdw_getabbrev) we
already check it is fully readable from the .debug_abbrev section. So
whenever we reread it later using the attrp pointer we don't have to
check it again. Introduce get_uleb128_unchecked to use for ulebs we
know are safe to read directly.

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.

All attributes now have a reference to a (fake) CU that has startp and
endp set to the data section where the form data comes from. Use that
for bounds checking in __libdw_form_val_len and dwarf_formblock to make
sure data read doesn't overflow any data section. Remove libdwP.h cu_data
and use cu startp and endp directly where appropriate.

Add a new internal function, __libdw_dieabbrev, which deals with checking
a die for an abbrev, and setting it as needed.

Pass endp as argument to __libdw_form_val_len and check we don't read
beyond the end of expected data and don't return lengths that would
overflow.
