[PATCHv2] gdbserver: Add .dir-locals.el file

[Andrew Burgess <andrew.burgess@embecosm.com>]

Baris,

Good spot on the *.h files, I hadn't considered them.  I did look
breifly at how I might change the mode only for *.h files, but
couldn't see anything obvious, and as we don't currently have any *.c
files I just restored the c-mode to c++-mode setting.

Thanks,
Andrew

Copy the .dir-locls.el file from gdb/ to gdbserver/ so that we get the
GNU style when editing these files in Emacs.

I initially wanted to remove the (c-mode . ((mode . c++))) that
switches c-mode files into c++-mode as we store C++ code in *.cc files
in the gdbserver/ directory, unlike gdb/ where we use *.c, however, I
was forgetting about the header files - we still use *.h for our C++
header files, so for now I left the settings in place to open all C
files in c++-mode.

The copyright date in the new file is left as for gdb/.dir-locals.el,
as the new file is a copy of the old with just one new comment
added, this is inline with this rule:
