This commit finishes the rework started by reverting changes to lib/sig2str.h, by adding Emacs-private additions to signal.h. * nt/inc/signal.h: New file, defines SIG2STR_MAX and prototypes of 'sig2str' and 'str2sig'.

/* Addition to system header signal.h file for building GNU Emacs on
|
|
Windows. It is needed because Posix mandates sig2str should appear
|
|
in signal.h, and Gnulib insists on assuming that, and the MinGW build
|
|
cannot use Gnulib's signal.h.
