Remove old files no longer needed.

Add new files created for emulator.
Modify NetBSD import to work with FreeBSD and add new features and
code.  The complete emulator is essentially a combination of work/code
implemented by Sean Eric Fagan, Soren Schmidt, Scott Bartram, and myself,
Steven Wallace.

Features of this new emulator system include:

 o  "clean" code, including strict prototyping.
 o  Auto-generation of ibcs2 system calls, xenix system calls, isc system
calls.  Generation includes system tables, structure definitions,
and prototyping of function calls.
 o  ibcs2 emulator does not rely on any COMPAT_43 system calls.
 o  embedded socksys support
 o  ibcs2 msgsys, semsys, shmsys calls supported if supported in kernel
 o  alternate /emul/ibcs2 namespace searched first for files in ibcs2
system.  Usefull to keep sysv libraries, binaries in /emul/ibcs2.
 o  many other finer details and functions fixed or implemented.
