Handle partial read or write.
Ran into a situation where pread was returning less data than requested for
remote files on a networked filesystem. This patch modifies the IO wrappers
to request the remaining data as long as no real errors occured.

Test elfutils output of a mixed core note.
This is a test for previous commit. The core file was snipped so that only
headers and note contents are left. NT_ARM_VFP is the note that exercises
the code.

In mixed core notes, don't let handle_core_item repeat.
If a core note contains both registers and items, descsz is 0 to express
that we don't wish to repeat the items. If there is only one item in
such note, a special block of code hits that passes &size to
handle_core_item, which will decrease that size by the amount consumed by
the item. But because size is 0, it underflows and wraps, and the loop
following this block, which handles the common case, overruns the core
note buffer.

Don't include dwz support by default.
By default the dwz multi file support is not included. This means any
DW_FORM_GNU_ref_alt or DW_FORM_GNU_strp_alt encountered in libdw will
just produce an error message. A new configure option --enable-dwz is
needed to include it for those we wish to test it. The dwz test is also
disabled by default.

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.

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...

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.
