Fixes a set of errors like:
../../src/gdb/symfile-debug.c: In function ‘int debug_qf_map_symtabs_matching_filename(objfile*, const char*, const char*, int (*)(symtab*, void*), void*)’:
../../src/gdb/symfile-debug.c:137:39: error: invalid conversion from ‘int (*)(symtab*, void*)’ to ‘const void*’ [-fpermissive]
host_address_to_string (callback),
^
Note this has to work with data and function pointers. In C++11 we
may perhaps do something a bit safer, but we're not there yet, and I
don't think it really matters. For now just always do a simple
C-style cast in host_address_to_string itself. No point in adding a
void * cast to each and every caller.

Using type bool from stdbool unfortunately causes problems trying
to build GDB on AiX and Solaris:
In file included from ../../src/gdb/utils.h:24:0,
from ../../src/gdb/defs.h:707,
from ../../src/gdb/utils.c:20:
/[...]/curses.h:96:14: error: two or more data types in declaration
specifiers
typedef char bool;
^
make[2]: *** [utils.o] Error 1
In theory, the problem is in curses.h which, in both cases, do
something similar. On Solaris:
#if !defined(__cplusplus) && !defined(_BOOL)
typedef char bool;
#endif /* !defined(__cplusplus) && !defined(_BOOL) */
On AiX:
#if !defined(__cplusplus) || (defined(__IBMCPP__) &&(__IBMCPP__<400))
#ifndef _BOOL
#define _BOOL
typedef int bool;
#endif
#endif
You can reproduce the same problem by trying to compile:
% cat toto.c
#include <stdbool.h>
#include <curses.h>
% gcc -c toto.c
In file included from toto.c:1:0:
/[...]/curses.h:159:13: error: two or more data types in declaration
specifiers
typedef int bool;
^
This specific issue wouldn't occur if we included curses.h before
including stdbool.h, and I looked at that just to be complete.
Here is a small schematic representation of the include logic:
* utils.c:
-> defs.h -> utils.h -> stdbool.h
-> gdb_curses.h -> curses.h
Because defs.h should always be first on the list, it means that
stdbool.h will always necessarily be included ahead of curses.h.
But, thinking beyond this very specific issue, it shows that using
stdbool.h is going to cause problems on these systems until either
GCC fixes those includes in a way that makes them work; or we switch
to C++.
In the meantime, I think the path of least resistance is to revert
the use of stdbool.h, and use integers, the way we've done up until
now. The benefits of using type "bool" are modest, IMO, so not
a great loss, and a temporary one.

I see the error message "access outside bounds of object referenced
via synthetic pointer" in the two fails below of mips gdb testing
print d[-2]^M
access outside bounds of object referenced via synthetic pointer^M

(gdb) FAIL: gdb.dwarf2/implptrpiece.exp: print/d p[-1]
in the first test, 'd[-2]' is processed by GDB as '* (&d[-2])'. 'd'
is a synthetic pointer, so its value is zero, the address of 'd[-2]'
is -2. In dwarf2loc.c:indirect_pieced_value,
/* This is an offset requested by GDB, such as value subscripts.
However, due to how synthetic pointers are implemented, this is
always presented to us as a pointer type. This means we have to
sign-extend it manually as appropriate. */

We know that the value is really an offset instead of address, so the
fix is to extract the value as an (signed) offset.

internal_vproblem can be called (via malloc_failure) from almost the
first line of captured_main, but it will crash if called before the
first call to set_width. This commit makes internal_vproblem work
at any time.
There are two parts to this. If called before gdb_stderr is set up,
internal_vproblem will fall back to printing the message on regular
stderr and aborting. If called after gdb_stderr is set up but before
filtered printing is set up, internal_vproblem will operate as usual
except that it can not query whether to quit and/or dump core so it
defaults to doing both.

GDB and gdbserver have functions named "fatal" that are used in
completely different ways. In gdbserver "fatal" is used to handle
critical errors: it differs from "error" in that "fatal" causes
gdbserver to exit whereas "error" does not. In GDB "fatal" is used
to abort the current operation and return to the command level.
This is implemented by throwing a non-error "RETURN_QUIT" exception.
This commit removes GDB's "fatal" and "vfatal" functions entirely.
The exception-throwing function "throw_vfatal" is renamed as
"throw_vquit", and a new convenience function "throw_quit" is added.
The small number of calls to "fatal" are replaced with calls to
"throw_quit", making what is happening more obvious.
This commit also modifies GDB's "throw_error" to call "throw_verror"
rather than calling "throw_it" directly. This change means the
assignment of RETURN_ERROR as the exception type now happens in
precisely one place in GDB rather than two.

This constifies the "args" argument to the target_ops to_attach
method.
I updated all instances of the method. I could not compile all of
them but I hand-inspected them. In all cases either the argument is
ignored, or it is passed to parse_pid_to_attach. (linux-nat does some
extra stuff, but that one I built...)
If you want to try it on your host of choice, please do so.
The code in parse_pid_to_attach seems a little bogus to me. If there
is a platform with a broken strtoul, we have better methods for fixing
the issue now. However, I left the code as is since it is clearly ok
to do so.
Built and regtested on x86-64 Fedora 20.

Consider the following example:
% gdb -q -batch -ex 'source nonexistant-file'
[nothing]
One would have at least expected the debugger to warn about
not finding the file, similar to the error shown when using
a more interactive mode. Eg:
(gdb) source nonexistant-file
nonexistant-file: No such file or directory.
Not raising an error appears to be intentional, presumably in order
to prevent this situation from stoping the execution of a GDB script.
But the lack of at least a warning makes it harder for a user to
diagnose any issue, if the file was expected to be there and readable.
This patch adds a warning in that case:
% gdb -q -batch -ex 'source nonexistant-file'
warning: nonexistant-file: No such file or directory.

PR symtab/15391 is a failure with the DW_OP_GNU_implicit_pointer
feature.
I tracked it down to a logic error in read_pieced_value. The code
truncates this_size_bits according to the type size and offset too
early -- it should do it after taking bits_to_skip into account.
This patch fixes the bug.
While testing this, I also tripped across a latent bug because
indirect_pieced_value does not sign-extend where needed. This patch
fixes this bug as well.
Finally, Pedro pointed out that a previous version implemented sign
extension incorrectly. This version introduces a new gdb_sign_extend
function for this. A couple of notes on this function:
* It has the gdb_ prefix to avoid clashes with various libraries that
felt free to avoid proper namespacing. There is a "sign_extend"
function in a Tile GX header, in an SOM-related BFD header (and in
sh64-tdep.c and as a macro in arm-wince-tdep.c, but those are
ours...)
* I looked at all the sign extensions in gdb and didn't see ones that
I felt comfortable converting to use this function; in large part
because I don't have a good way to test the conversion.
Built and regtested on x86-64 Fedora 18. New test cases included;
this required a minor addition to the DWARF assembler. Note that the
DWARF CU made by implptrpiece.exp uses a funny pointer size in order
to show the sign-extension bug on all platforms.
