simplify target_is_pushed

While working on target_is_pushed, I noticed that it is written in a
strange way.  The code currently keeps an extra indirection, where a
simple linked list traversal is all that is needed.  It seems likely
this was done by copying and pasting other code.  However, there is no
reason to do this and the more obvious code is simpler to reason
about.  So, this patch change the implementation.

	* target.c (target_is_pushed): Simplify.

Make all source files include defs.h or server.h first

This commit makes all source files under gdb/ that include headers
from gdb/ include either defs.h or server.h before any other code.
This ensures that definitions and macros from the two config.h files
are always in place for our code.  An exception has been made for
gdb/gdbserver/gdbreplay.c which seems to be a special case.

	* common/ptid.c: Include defs.h or server.h as appropriate.
	* nat/mips-linux-watch.c: Likewise.

Do not include config.h directly

All source files under gdb/ that include headers from gdb/ include
either defs.h or server.h before any other code with the exception
of gdb/gdbserver/gdbreplay.c which seems to be a special case.  Both
defs.h and server.h include both our and gnulib's config.h files as
their first non-comment line, so no other file ever needs to directly
include any config.h.  This commit removes two such direct config.h
includes.

Introduce common/common-defs.h

This commit creates a new header, common/common-defs.h, to hold
definitions common to all code under gdb/.  Both gdb/defs.h and
gdb/gdbserver/server.h are modified to include common-defs.h as
their first non-comment line; all code under gdb/ includes either
defs.h or server.h as appropriate, so common-defs.h will be the
first actual code the compiler sees.

For this initial commit common-defs.h includes only the two
config.h files.  Future commits will move more code currently
duplicated across defs.h and server.h such that shared code in
gdb/{common,target,nat} can be modified to include common-defs.h
rather than defs.h or server.h.

Update comments to operator_check

Hello,
I happen to read the code and find the comments to operator_check are
incorrect.  This patch is to fix the comments per my understanding.
The comments and field operator_check was added by this patch

  https://sourceware.org/ml/gdb-patches/2010-04/msg00556.html

but the inconsistency between code and comments wasn't pointed out during
the review.

fix to_open debug setting

This is a follow-on to the patch to auto-generate target debug methods.

While working on that patch I noticed that the to_open debug setting
will never work.  There is no path by which debug_to_open can be
called.

This patch fixes the problem by using a generic function as the
implementation of the various "target" subcommands, and then putting
the debug printing there.

This is also a tiny step toward fixing PR 7250 (and apparently why
command contexts were introduced).

Built and regtested on x86-64 Fedora 20.

	* target.c (open_target): New function.
	(add_target_with_completer, add_deprecated_target_alias): Use
	set_cmd_sfunc, set_cmd_context.
	(debug_to_open): Remove.
	(setup_target_debug): Update.
constify exec_file_attach

This constifies exec_file_attach and updates the rest of gdb.

Insight will need some minor tweaks after this, though it's worth
noting that I think all that hook stuff can actually just go away.  I
sent a patch to this effect once, but since the Insight source
repository situation isn't currently resolved there wasn't a
convenient way to test it.

constify some cli-utils stuff

This constifies a few functions in cli-utils -- get_number_trailer and
friends -- and then fixes the fallout.

	* value.c (value_from_history_ref): Constify.

constify to_open

This makes target_ops::to_open take a const string and then fixes the
fallout.

There were a few of these I could not build.  However I eyeballed it
and in any case the fixes should generally be trivial.

This is based on the patch to fix up the target debugging for to_open,
because that changes gdb to not directly install to_open as the target
command
