When we see a DW_AT_decl_file or DW_AT_call_file attribute print the
actual file name. The current interface gives us a full (absolute) patch,
but we only want to show the file name for now to not clutter the output
too much. This helps a lot when trying to determine where something was
declared if you are just looking at the DIE tree. Otherwise you'll have
to cross match the number by hand with the corresponding line table entry.

If there is anything wrong with a DIE it is useful to know what the abbrev
code was so you can lookup the abbrev description.

Use only 2 spaces for index (there are never 10000, the most seen in the
wild is 64). Adjust re-indenting after GNU_entry_value.

Those are deprecated and apparently some implementations of nl_langinfo
return empty strings for them. The tests even tested for those empty
strings even though the intention of the code was clearly to output
"yes" or "no" there.

Don't hard code the Dwarf dwz alt multi file search but allow the user
to override it through the standard Dwfl_Callbacks. Also move ownership
completely to the user of dwarf_setalt by removing free_alt from Dwarf
and adding alt, fd and elf fields to Dwfl_Module. Add a relative .dwz
file test case.

The parallel-tests option was introduced in automake 1.11 and is the
default since automake 1.13. All tests can now be ran in parallel with
make check -j. To enable this all tests are ran in their own temporary
directory so they don't stomp on each others input or output files.
On my machine (4 cores) make check takes ~20 seconds, but now with
make check -j8 takes only ~4 seconds.
ChangeLog:
* configure.ac (AM_INIT_AUTOMAKE): Request parallel-tests.
tests/ChangeLog:
* Makefile.am (installed_TESTS_ENVIRONMENT): Export environment,
remove wrapper.
(TESTS_ENVIRONMENT): Likewise.
(installed_LOG_COMPILER): New variable defining wrapper.
(LOG_COMPILER): Likewise.
* run-*.sh: Fixup location of input and output files.
* test-subr.sh: Create test_dir, pushd to execute test in.
(trap): Remove test_dir.
(testfiles): Use abs_srcdir.
(installed_testrun): Match on abs_builddir or abs_top_builddir.
(self_test_files): Adjust path.

When highpc is in constant form it is relative to lowpc. In that case
also show as address.

dwarf_formstring should check that the dbg file from which we want the
strp data actually has a IDX_debug_str section.

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.

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.
