SVR4 emulator source files now take their compilation options from

opt_global.h and opt_svr4.h, instead of from the command line.  This
brings them in-line with most of the rest of the kernel.

svr4_ioctl.c has also failed to compile with debugging for a while
now;  fixed by adding systm.h and socketvar.

Some svr4 source files are automatically generated from syscalls.master;
these have been committed as consequential changes, otherwise everyone
will have to "make svr4_sysent.c".

Changes:

sys/svr4/svr4.h			include opt_global.h and opt_svr4.h
sys/svr4/svr4_ioctl.c		include svr4.h, sys/systm.h and sys/socketvar.h
sys/svr4/svr4_ipc.c		include svr4.h
sys/svr4/svr4_resource.c 	include svr4.h
sys/svr4/svr4_socket.c		include svr4.h
sys/svr4/svr4_ttold.c		include svr4.h
sys/svr4/syscalls.master	include svr4.h
sys/svr4/svr4_syscallnames.c	dependent on syscalls.master
sys/svr4/svr4_sysent.c		dependent on syscalls.master
sys/svr4/svr4_syscall.h		dependent on syscalls.master
sys/svr4/svr4_proto.h		dependent on syscalls.master
sys/modules/svr4/Makefile	create opt_global.h and opt_svr4.h
