Typo fix in signal_pass initialization

When I read the code, I happen to see this:

   signal_pass = (unsigned char *)
     xmalloc (sizeof (signal_program[0]) * numsigs);
                      ^^^^^^^^^^^^^^
It is a typo, and this patch is to fix it.

	* infrun.c (_initialize_infrun): Replace "signal_program[0]"
	with "signal_pass[0]" in the initialization of signal_pass.
Fixes a problem displaying the contents of a binary containing corrupt debug
information, specifically a DW_AT_MIPS_linkage_name attribute that has a numeric
value rather than a string value.

	PR binutils/16949
	* dwarf2.c (is_str_attr): New function.
	(find_abstract_instance_name): Use it to determine when an
	attribute has a string value.
Move local variables to inner block

dummy_frame_sniffer has two local variables dummyframe and this_id,
but they are only used in the if block below.  This patch is to move
them into the inner block.

gdb:

2014-06-26  Yao Qi  <yao@codesourcery.com>

	* dummy-frame.c (dummy_frame_sniffer): Move local variables
	dummyframe and this_id into inner block below.
Fixes part of a problem reading deliberately non-conforming ELF binaries - where a
note segment is present but no note section.

	* readelf.c (process_note_sections): If there are no note sections
	try processing note segments instead.
Change the default behaviour of the PE targeted linker so that timestamps are
inserted.  This is for compatibility with other, non-GNU tools.  Deterministic
binaries can still be created by using the new --no-insert-timestamp command line
option.

	* emultempl/pe.em: Initialise insert_timestamp to true.
	Add a --no-insert-timestamp command line option.
	* emultempl/pep.em: Likewise.
	* ld.texinfo: Document that --insert-timestamp is enabled by
	default and that it now has an inverse command line option.
	* NEWS: Mention the new behaviour.
Fix a compile time warning on 32-bit hosts.

	* or1k-desc.h (spr_field_masks): Add U suffix to the end of long
	constants.
This adds the ability to the strings program to display strings that contain \n and \r characters.

	* strings.c: Add -w/--include-all-whitespace option to include any
	whitespace character in the displayed strings.
	* NEWS: Mention the new feature.
	* doc/binutils.texi (strings): Document the new command line
	option.
fix memory errors with demangled name hash

This fixes a regression that Jan pointed out.

The bug is that some names were allocated by dwarf2read on the objfile
obstack, but then passed to SYMBOL_SET_NAMES with copy_name=0.  This
violates the invariant that the names must have a lifetime tied to the
lifetime of the BFD.

The fix is to allocate names on the per-BFD obstack.

I looked at all callers, direct or indirect, of SYMBOL_SET_NAMES that
pass copy_name=0.  Note that only the ELF and DWARF readers do this;
other symbol readers were never updated (and perhaps cannot be,
depending on the details of the formats).  This is why the patch is
relatively small.

Built and regtested on x86-64 Fedora 20.

constify to_load

This makes the argument to the target_ops to_load method "const", and
fixes up the fallout.  Tested by rebuilding all the affected files.

constify get_bookmark and goto_bookmark

This makes arguments to to_get_bookmark and to_goto_bookmark const and
fixes the fallout.  Tested by rebuilding.  The only thing of note is
the new split between cmd_record_goto and record_goto -- basically
separating the CLI function from a new internal API, to allow const
propagation.

2014-06-26  Tom Tromey  <tromey@redhat.com>

	* record-full.c (record_full_get_bookmark): Make "args" const.
	(record_full_goto_bookmark): Make "raw_bookmark" const.

	* record.h (record_goto): Declare.
	(cmd_record_goto): Remove declaration.
	* target-delegates.c: Rebuild.
	* target.h (struct target_ops) <to_get_bookmark,
	to_goto_bookmark>: Make parameter const.
constify do_set_command and do_show_command

This changes do_set_command and do_show_command to take const
arguments.

	* cli/cli-setshow.c (do_set_command): Make "arg" const.

This is a trivial patch to make error_no_arg take a const argument.

2014-06-26  Tom Tromey  <tromey@redhat.com>

	* cli/cli-cmds.c (error_no_arg): Make "why" const.
	* command.h (error_no_arg): Update.

Associate dummy_frame with ptid

This patch is to add ptid into dummy_frame and extend frame_id to
dummy_frame_id (which has a ptid field).  With this change, GDB uses
dummy_frame_id (thread ptid and frame_id) to find the dummy frames.

Currently, dummy frames are looked up by frame_id, which isn't
accurate in non-stop or multi-process mode.  The test case
gdb.multi/dummy-frame-restore.exp shows the problem and this patch can
fix it.

Test dummy-frame-restore.exp makes two inferiors stop at
different functions, say, inferior 1 stops at f1 while inferior 2
stops at f2.  Set a breakpoint to a function, do the inferior call
in two inferiors, and GDB has two dummy frames of the same frame_id.
When the inferior call is finished, GDB will look up a dummy frame
from its stack/list and restore the inferior's regcache.  Two
inferiors are finished in different orders, the inferiors' states are
restored differently, which is wrong.  Running dummy-frame-restore.exp
under un-patched GDB, we'll get two fails:

FAIL: gdb.multi/dummy-frame-restore.exp: inf 2 first: after infcall: bt in inferior 2
FAIL: gdb.multi/dummy-frame-restore.exp: inf 2 first: after infcall: bt in inferior 1

With this patch applied, GDB will choose the correct dummy_frame to
restore for a given inferior, because ptid is considered when looking up
dummy frames.  Two fails above are fixed.

Regression tested on x86_64-linux, both native and gdbserver.
