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".
