gdb/ChangeLog
Update copyright year range in copyright header of all GDB files.
Use the LOCALAPPDATA environment variable to determine the cache dir
when running on Windows with native command line, otherwise nasty
warning "Couldn't determine a path for index cached directory" appears.

A recent commit caused pathstuff.cc to fail to compile on mingw, like:
../../binutils-gdb/gdbsupport/pathstuff.cc:324:1: error: no previous declaration for 'std::string find_gdb_home_config_file(const char*, _stati64*)' [-Werror=missing-declarations]
Some newly-added #includes were changing which "stat" was being seen
by the compiler. This patch moves the includes to the header, so that
the declaration and definition now agree.

* pathstuff.h: Move include block here...
* pathstuff.cc: ... from here.
This commit effectively changes the default location of the .gdbinit
file, while maintaining backward compatibility.
For non Apple hosts the .gdbinit file will now be looked for in the
following locations:
$XDG_CONFIG_HOME/gdb/gdbinit
$HOME/.config/gdb/gdbinit
$HOME/.gdbinit
On Apple hosts the search order is instead:
$HOME/Library/Preferences/gdb/gdbinit
$HOME/.gdbinit
I've performed an extensive rewrite of the documentation, moving all
information about initialization files and where to find them into a
new @node, text from other areas has been moved into this one
location, and other areas cross-reference to this new @node as much as
possible.
gdb/ChangeLog:
* NEWS: Mention changes to config file search path.
* main.c
gdb/doc/ChangeLog:
* gdb.texinfo (Mode Options): Descriptions of initialization files
has been moved to 'Initialization Files'.
(Startup): Likewise.
(Initialization Files): New node.
(gdb man): Update to mention alternative file paths.
(gdbinit man): Likewise.
This adds a new get_standard_config_dir, which returns the name of the
configuration directory. In XDG, this is ~/.config/gdb/. Future
patches will make use of this.

* pathstuff.h (get_standard_config_dir): Declare.
* pathstuff.cc (get_standard_config_dir): New function.
This patch renames the .c source files in gdbsupport to .cc.
In the gdb directory, there is an argument against renaming the source
files, which is that it makes using some git commands more difficult to
do archeology. Some commands have some kind of "follow" option that
makes git try to follow renames, but it doesn't work in all situations.
Given that we have just moved the gdbsupport directory, that argument
doesn't hold for source files in that directory. I therefore suggest
renaming them to .cc, so that they are automatically recognized as C++
by various tools and editors.
The original motivation behind this is that when building gdbsupport
with clang, I get:
CC agent.o
clang: error: treating 'c' input as 'c++' when in C++ mode, this behavior is deprecated [-Werror,-Wdeprecated]
In the gdb/ directory, we make clang happy by passing "-x c++". We
could do this in gdbsupport too, but I think that renaming the files is
a better long-term solution.
gdbserver still does its own build of gdbsupport, so a few changes in
its Makefile are necessary.
gdbsupport/ChangeLog:
* Makefile.am: Rename source files from .c to .cc.
(CC, CFLAGS): Don't override.
(AM_CFLAGS): Rename to ...
(AM_CXXFLAGS): ... this.
* Makefile.in: Re-generate.
* %.c: Rename to %.cc.
gdbserver/ChangeLog:
* Makefile.in: Rename gdbsupport source files from .c to .cc.
