Tankut Baris Aktemur 842806cb6f gdb, gdbserver, gdbsupport: add .gitattributes files
Create .gitattributes files in gdb/, gdbserver/, and gdbsupport/.

The files specify cpp-style diffs for .h and .c files.  This is
particularly helpful if a class in a header file is modified.
For instance, if the `stop_requested` field of `thread_info` in
gdb/gdbthread.h is modified, we get the following diff with
'git diff' (using git version 2.17.1):

   @@ -379,7 +379,7 @@ public:
      struct target_waitstatus pending_follow;

      /* True if this thread has been explicitly requested to stop.  */
   -  int stop_requested = 0;
   +  bool stop_requested = 0;

      /* The initiating frame of a nexting operation, used for deciding
         which exceptions to intercept.  If it is null_frame_id no

Note that the context of the change shows up as 'public:'; not so
useful.  With the .gitattributes file, we get:

The context is successfully shown as 'class thread_info'.

This patch creates a .gitattributes file per each of gdb, gdbserver,
and gdbsupport folders.  An alternative would be to define the
attributes in the root folder -- this would impact all the top-level
folders, though.  I opted for the more conservative approach.
