Rewrite DWARF string functions using known-dwarf macros.
readelf and tests were using hard coded string tables to produce DWARF
string constants. Use the known-dwarf macros to redefine these and
reduce code. Technique comes from dwarf branch dwarfstrings.c.

libdw: Add support for DWZ multifile forms DW_FORM_GNU_ref_alt/strp_alt.
DWZ multifile forms http://www.dwarfstd.org/ShowIssue.php?issue=120604.1
DW_FORM_GNU_ref_alt and DW_FORM_GNU_strp_alt reference an alternative
debuginfo file. dwarf_begin and dwarf_begin_elf will try to use this
automatically. There are no user visible changes to the libdw interface.
dwarf_formref_die, dwarf_formstring and dwarf_formudata can now return
a Dwarf_Die which comes from a CU in the alternative Dwarf descriptor.
__libdw_read_offset was adjusted to take an alternative Dwarf descriptor
into account.

tests: only compile test programs when running test
The test binaries are only needed by make check, so change the PROGRAMS
category from noinst_ to check_ to speed up default `make && make install`.
If people want to run the tests, then the utilities will be compiled
automatically when they run `make check`, so the normal workflow should
be unchanged.

elf32_offscn.c: Do not match SHT_NOBITS sections at OFFSET.
readelf -d doesn't work if a SHT_NOBITS section is right before the actual
.dynamic section at the same offset. elflint also fails on such binaries.
So skip SHT_NOBITS sections at the same offset in [g]elf[32|64]_offscn().

Fix bug using dwarf_next_unit to iterate over .debug_types
* libdw_findcu.c (findcu_cb): Move earlier.
(__libdw_intern_next_unit): Add new CU to search tree here...
(__libdw_findcu): ... not here.
* typeiter.c: New file.
* run-typeiter.sh: New file.
* testfile59.bz2: New file.
* Makefile.am (noinst_PROGRAMS): Add typeiter.
(TESTS): Add run-typeiter.sh.
(EXTRA_DIST): Add run-typeiter.sh, testfile59.bz2.
(typeiter_LDADD): New variable.
If you call dwarf_next_unit to iterate over .debug_types, then call
dwarf_offdie_types, you can see a failure if some earlier call
happened to call __libdw_intern_next_unit via dwarf_formref_die.
What happens is that __libdw_intern_next_unit updates the Dwarf's
next_tu_offset, but does not add the TU to the TU search tree. So,
the call to dwarf_offdie_types does not find the TU in the tree, and
will not search any more, causing a failure.
This fix changes __libdw_intern_next_unit to add the TU to the search
tree, rather than relying on __libdw_findcu to do it.

Use index of first global symbol to speed up dwfl_module_addrsym search.
Cache the index of the first global symbol in the module's symbol table,

Improve nm output for BSD and POSIX format
The binutils version showed more information since it distinguished
unique symbols, symbols in read-only and bss sections. The format
is now the same. In addition handle TLS symbols correctly but
differently from binutils nm since the latter drops information.
Instead use a @ suffix to indicate TLS similar to * to indicate
weak.
