Handle MAP_ANON (0x100 in Solaris8, not 0x1000) properly, by factoring out the flags common to SVR4 and NetBSD, and mapping the rest manually.

/* $NetBSD: svr4_mman.h,v 1.3 2002/02/07 23:22:24 tv Exp $ */
From Todd Vierling: - Fix memcntl() - Fixed stat and mknod syscalls to properly disassemble and reassemble dev_t values to/from emulation dev_t's - Added pty (ptmx) subsystem at svr4net minor number 10 -- /dev/ptmx - Implemented fork1() as fork() (should change if and when threads get added to the system) - fixed spellings in disclaimer in svr4_net.c; it looks like someone went and did a s/nd/st/g on the whole file... yuck - changed ptmx device to also halt on ENXIO (for pty files that exist with no kernel pty to back them) - fixed SVR4 setpgrp() to be a near equivalent to BSD setsid() (old emulation didn't create a new session)
