the semantics in that the returned filename to use is now a kernel

arguments to the CHECKALT*() macros some and changing the various system
calls that used pathnames to use the kern_foo() functions that can accept
kernel space filename pointers instead of calling the system call
directly.
- Use kern_open(), kern_access(), kern_execve(), kern_mkfifo(), kern_mknod(),

- Implement ibcs2_emul_find() using kern_alternate_path(). This changes
the semantics in that the returned filename to use is now a kernel
pointer rather than a user space pointer. This required changing the
arguments to the CHECKALT*() macros some and changing the various system
calls that used pathnames to use the kern_foo() functions that can accept
kernel space filename pointers instead of calling the system call
directly.
- Use kern_open(), kern_access(), kern_execve(), kern_mkfifo(), kern_mknod(),
kern_setitimer(), kern_getrusage(), kern_utimes(), kern_unlink(),
kern_chdir(), kern_chmod(), kern_chown(), kern_symlink(), kern_readlink(),
kern_select(), kern_statfs(), kern_fstatfs(), kern_stat(), kern_lstat(),
kern_fstat().
- Drop the unused 'uap' argument from spx_open().
- Replace a stale duplication of vn_access() in xenix_access() lacking
recent additions such as MAC checks, etc. with a call to kern_access().

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.
