Handle all new DW_RLE opcodes in .debug_rnglists in dwarf_ranges. Extract
code for reading .debug_addr indexes from dwarf_formaddr as __libdw_addrx
to reuse in __libdw_read_begin_end_pair_inc. And add new testcase for
"plain" DWARF5 and add a new test all-dwarf-ranges to test split DWARF5.

DW_OP_addrx/constx and GNU DebugFission DW_OP_GNU_addr/const_index take
as argument an index into the .debug_addr section for the associated CU.
This index gets resolved through dwarf_getlocation_attr. A new fake addr
CU is created per Dwarf for use with this new attribute. For split DWARF
files, the IDX_debug_addr gets replaced with the skeleton section and the
addr base is resolved immediately when constructing the split DWARF CU.
Move __libdw_cu_addr_base to libdwP.h to share with eu-readelf. Also
make it possible to resolve addrx[1234]/GNU_addr_index also as constant
indexes to (also) show when displaying these attributes in eu-readelf.
A new varlocs tests is added to test the resolving for both the DWARF4
and DWARF5 DW_OP variants. And now that addrx forms are resolved in
split DWARF files add the new DIEs with "single ranges" (those DIEs that
have a lowpc/highpc attribute pair) to run-all-dwarf-ranges.sh.

Most are handled just like their DWARF5 counterparts.

Recognize the new .debug_addr section. The CU will now hold a new
address base offset in that section for that CU. dwarf_form_addr will
decode DW_FORM_addrx[1234] and return addresses using that address
base from the .debug_addr. A new internal function read_3ubyte_unaligned
will try to read a 24-bit value depending on endianness of the underlying
file.

We already require -std=gnu99 and old-style function definitions might
hide some compiler warnings.

Rewrites in read hooks

this in the header.
