[RFC] Internationalization markup of messages and common code

["Pierre Muller" <pierre.muller@ics-cnrs.unistra.fr>]

  As I recently added the gettext category to 
standard ARI output, I found out that 
common/signals.c has calls to error and warning functions
without _() markups.
  Trying to add them, I realized that the problem
was that gdbserver did not use those markups.
  This leads to a conflict between gdbserver code
that has no internalization and gdb that requires it.

  The following patch adds a no-op underscore macro
to server.h in gdbserver sub-directory, allowing thus to use
_ macro in any new common code (I still have some
code of this kind to prepare for submission...).

  I have no idea if this is the correct answer to
the problem I raised above, but for me it seemed
a simple answer.

  All opinions welcome,

PS: This is an illustration of the multiple ChangeLog 
problem, this is really a unique patch,
but with two independent entries, this link will be lost..
Should I add a cross-reference to the other ChangeLog here?


Proposed patch:
