This patch moves the shared code present on
gdb/linux-nat.c:linux_nat_create_inferior and
gdb/gdbserver/linux-low.c:linux_create_inferior to
nat/linux-personality.c. This code is responsible for disabling
address space randomization based on user setting, and using
<sys/personality.h> to do that. I decided to put the prototype of the
maybe_disable_address_space_randomization on nat/linux-osdata.h
because it seemed the best place to put it.
I regression-tested this patch on Fedora 20 x86_64, and found no
regressions.

* NEWS: Mention the change.
The type of the function pointer PyOS_ReadlineFunctionPointer (part of the
Python C API), which we use, slightly changed starting with Python 3.4. The
signature went from
PyAPI_DATA(char) *(*PyOS_ReadlineFunctionPointer)(FILE *, FILE *, char *);
to
PyAPI_DATA(char) *(*PyOS_ReadlineFunctionPointer)(FILE *, FILE *, const char *);
The parameter that changed is the prompt text.
This commits adjust gdb accordingly by making the prompt_arg parameter
const, as well as the fallouts of that. I needed to rework how
annotations are added to the prompt, since the it is now const. If
annotations are enabled, it will make a copy of the prompt overwrite the
prompt variable that is used throughout the function. Otherwise, no copy
is done and the original prompt_arg value is passed.
I changed the signature of deprecated_readline_hook. I would've changed any
user of it, but it seems like nothing is using it,
Built-tested with python 2.7.x, 3.3.y and 3.4.z.
gdb/ChangeLog:
* defs.h (gdb_readline): Constify argument.
(gdb_readline_wrapper): Same.
(command_line_input): Same.
(deprecated_readline_hook): Same.
* top.c (deprecated_readline_hook): Same.
(gdb_readline): Same.
(gdb_readline_wrapper): Same.
(command_line_input): Constify argument. Pass prompt to
called functions instead of local_prompt, overwriting prompt
if using annotations.
* event-top.h (display_gdb_prompt): Constify argument.
* event-top.c (display_gdb_prompt): Same.
* python/py-gdb-readline.c (gdbpy_readline_wrapper): Constify
argument if building with Python 3.4 and up.

This final patch adds the new "compile" command and subcommands, and
all the machinery needed to make it work.
A shared library supplied by gcc is used for all communications with
gcc. Types and most aspects of symbols are provided directly by gdb
to the compiler using this library.
gdb provides some information about the user's code using plain text.
Macros are emitted this way, and DWARF location expressions (and
bounds for VLA) are compiled to C code.
This hybrid approach was taken because, on the one hand, it is better
to provide global declarations and such on demand; but on the other
hand, for local variables, translating DWARF location expressions to C
was much simpler than exporting a full compiler API to gdb -- the same
result, only easier to implement, understand, and debug.
In the ordinary mode, the user's expression is wrapped in a dummy
function. After compilation, gdb inserts the resulting object code
into the inferior, then calls this function.
Access to local variables is provided by noting which registers are
used by location expressions, and passing a structure of register
values into the function. Writes to registers are supported by
copying out these values after the function returns.
This approach was taken so that we could eventually implement other
more interesting features based on this same infrastructure; for
example, we're planning to investigate inferior-side breakpoint
conditions.

Since gnulib alloca module was imported, we can include alloca.h in
both gdb and gdbserver unconditionally, so this patch adds inclusion
of alloca.h in common-defs.h. This patch also removes AC_FUNC_ALLOCA
in configure.ac because we don't need to check alloca any more.
This patch below is removed in fact.
[RFA/commit] include alloca.h if available.
https://www.sourceware.org/ml/gdb-patches/2010-08/msg00566.html

configure and include malloc.h in code. This patch also remove them
too.

This commit does most of the mechanical removal. IOW, the easy part.
procfs.c isn't touched beyond removing a couple obvious bits that are
guarded by a couple macros defined in config/alpha/nm-osf3.h. Going
beyond that for procfs.c & co would be a harder excision that
potentially affects Solaris.
Some comments in the generic alpha code ABIs that may still be
relevant and I wouldn't know what to do with them. That can always be
done on a separate pass, preferably by someone who can test on alpha.
A couple other spots have references to OSF/Tru64 and related files
being removed, but it felt like removing them would make things worse,
not better. We can revisit those when we next need to touch that
code.
I didn't remove a reference to osf in testsuite/lib/future.exp, as I
believe that code is imported from DejaGNU.
Built and tested on x86_64 Fedora 20, with --enable-targets=all.
Tested that building for --target=alpha-osf3 on x86_64 Fedora 20
fails with:

This introduces common-types.h. This file defines various standard
types used by gdb and gdbserver.
Currently these types are conditionally defined based on GDBSERVER.
The long term goal is to remove all such tests; however, this is
difficult as currently gdb uses definitions from BFD. In the meantime
this is still a step in the right direction.

This commit moves the inclusion of errno.h to common-defs.h and

server.h included errno.h protected by "#ifdef HAVE_ERRNO_H".
This protection was added with the Windows CE port, which is
currently broken. Since no other platform needs this, I have
removed the protection and the configury to support it.

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.

exec_set_find_memory_regions is used to modify the exec target.
However, it only has a single caller, and so it is much clearer to
simply set the appropriate field directly. It's also better for the
coming multi-target world to avoid this kind of global state change
anyway.

With the pathmax gnulib module in place, we can use PATH_MAX
consistently throughout, instead of the current mixbag of PATH_MAX and
MAXPATHLEN uses. It's no longer necessary to include sys/param.h
(supposedly, I can't check all ports touched here) for MAXPATHLEN.
Don't remove sys/param.h from GDB's configure.ac, as later tests in
the file use HAVE_SYS_PARAM_H checks.
Tested on x86_64 Fedora 17.
Also cross-built for --host=i686-w64-mingw32, and --host=i586-pc-msdosdjgpp.
