New macros NULL_DEVICE and EXEC_SUFFIXES, to give the name of the
equivalent of /dev/null, and the suffixes used by executable files. This is simple, and helps people porting Emacs to other operating systems. * process.h (NULL_DEVICE): Give this a default value. * process.c (Fstart_process): Pass EXEC_SUFFIXES to openp. (Fprocess_send_eof): Use NULL_DEVICE instead of "/dev/null". * callproc.c (Fcall_process): Pass EXEC_SUFFIXES to openp. Use NULL_DEVICE instead of "/dev/null".
