Remove unused arguments to few functions in dwarf2loc.c and gdbtypes.c.

gdb/ChangeLog:

	* dwarf2loc.c (dwarf2_locexpr_baton_eval,
	dwarf2_evaluate_property): Remove unused CORE_ADDR argument.
	Update all callers.
	* dwarf2loc.h (dwarf2_evaluate_property): Update signature.
	* gdbtypes.c (resolve_dynamic_range, resolve_dynamic_array):
	Remove unused CORE_ADDR argument.  Update all callers.
Fixes a problem with the BFD library running out of memory because it mistakenly
thought that an uncompressed .debug_str section was compressed.

	* compress.c (bfd_is_section_compressed): When checking the
	.debug_str section, also check the fifth byte in the section is
	not part of a string.

	* binutils-all/debug_str.s: New test.
	* binutils-all/debug_str.d: New test control file.
	* binutils-all/compress.exp: Run debug_str test.

Rename testsuite/boards/local-remote-host.exp -> testsuite/boards/local-remote-host-notty.exp

When testing with this board, stdin is not a tty, and so
readline/editing is disabled:

 $ ssh localhost gdb -q
 (gdb) show editing
 Editing of command lines as they are typed is off.
 (gdb)

Rename the file, to make room for a version of this board that forces a pseudo-tty.

	* boards/local-remote-host-notty.exp: ... this.
New testsuite/boards/local-remote-host.exp board, now with editing on

This adds a variant of local-remote-host-notty.exp that forces
pseudo-tty allocation, so that readline/editing is enabled.

 $ ssh localhost gdb -q
 (gdb) show editing
 Editing of command lines as they are typed is off.
 (gdb)

vs:

 $ ssh -t localhost gdb -q
 (gdb) show editing
 Editing of command lines as they are typed is on.

We now get, e.g.:

 Running ../../../src/gdb/testsuite/gdb.base/filesym.exp ...
 PASS: gdb.base/filesym.exp: complete on "filesy"
 PASS: gdb.base/filesym.exp: completion list for "filesym"

Handle prefixes before fwait

0x9b (fwait) is both an instruction and an opcode prefix.  When 0x9b is

compare-sections: New -r option.

When connecting to a remote system, we use the compare-sections
command to verify that the box is running the code that we think it is
running.  Since the system is up and running and *NOT* 'freshly
downloaded without yet executing anything', read-write sections, of
course, differ from what they were in the executable file.

Comparing read-write sections takes time and more importantly the
MIS-MATCHED output is confusing to some users.

The compare-sections command compares all loadable sections including
read-write sections.  This patch gives the user the option to compare
just the loadable read-only sections.

gdb_load: Fix latent bugs

In a test I was writting, I needed a procedure that would connect to
the target, and do "load", or equivalent.

Years ago, boards would override gdb_load to implement that.  Then
gdb_reload was added, and gdb_load was relaxed to allow boards avoid
the spawing and connecting to the target.  This sped up gdbserver
testing.  See
https://www.sourceware.org/ml/gdb-patches/2007-02/msg00318.html.

To actually spawn the target and load the executable on the target
side, gdb_reload was born:

 # gdb_reload -- load a file into the target.  Called before "running",
 # either the first time or after already starting the program once,
 # for remote targets.  Most files that override gdb_load should now
 # override this instead.

 proc gdb_reload { } {
     # For the benefit of existing configurations, default to gdb_load.
     # Specifying no file defaults to the executable currently being
     # debugged.
     return [gdb_load ""]
 }

Note the comment about specifying no file.  Indeed looking at
config/sid.exp, or config/monitor.exp, we see examples of that.

However, the default gdb_load itself doesn't handle the case of no
file specified.  When passed no file, it just calls gdb_file_cmd with
no file either, which ends up invocing the "file" command with no
argument, which means unloading the file and its symbols...  That
means calling gdb_reload when testing against native targets is
broken.  We don't see that today because the only call to gdb_reload
that exists today is guarded by target_info exists
gdb,do_reload_on_run.

The native-extended-gdbserver.exp board is likewise broken here.  When
[gdb_load ""] is called, the board sets the remote exec-file to "" ...

Tested on x86_64 Fedora 17, native, remote gdbserver and
extended-remote gdbserver.

	* lib/gdb.exp (gdb_load): Extend comment.  Skip calling
	gdb_file_cmd if no file is specified.

bfd target vector rationalisation

This renames the bfd targets to <cpu>_<format>_<other>_<endian>_vec.
So for example, bfd_elf32_ntradlittlemips_vec becomes
mips_elf32_ntrad_le_vec and hp300bsd_vec becomes m68k_aout_hp300bsd_vec.

Fix PR breakpoints/16889: gdb segfaults when printing  ASM SDT arguments

This commit fixes PR breakpoints/16889, which is about a bug that
triggers when GDB tries to parse probes whose arguments do not contain
the initial (and optional) "N@" part.  For reference sake, the de
facto format is described here:

  <https://sourceware.org/systemtap/wiki/UserSpaceProbeImplementation>

Anyway, this PR actually uncovered two bugs (related) that were
happening while parsing the arguments.  The first one was that the
parser *was* catching *some* arguments that were missing the "N@"
part, but it wasn't correctly setting the argument's type.  This was
causing a NULL pointer being dereferenced, ouch...

The second bug uncovered was that the parser was not catching all of
the cases for a probe which did not provide the "N@" part.  The fix
for that was to simplify the check that the code was making to
identify non-prefixed probes.  The code is simpler and easier to read
now.

I am also providing a testcase for this bug, only for x86_64
architectures.

Extend recognized types of SDT probe's arguments

This commit is actually an update to make the parser in
gdb/stap-probe.c be aware of all the possible prefixes that a probe
argument can have.  According to the section "Argument Format" in:

  <https://sourceware.org/systemtap/wiki/UserSpaceProbeImplementation>

The bitness of the arguments can be 8, 16, 32 or 64 bits, signed or
unsigned.  Currently GDB recognizes only 32 and 64-bit arguments.
