6c68c84345 Use argname PAD to signal that an argument is used only for padding 
and not part of the C interface.  Use this information for rump
syscalls to generate syscall interfaces without the extra parameter.

a9a2ce837b Convert the syscalls.master to a format from which it is easier 
to parse and generate the compat name and basename (e.g. __stat50
and stat).  Use this to autogenerate __RENAME()'s to the rump_syscalls
header so that they can be called e.g. rump_sys_socket() instead
of rump_sys___socket30().

92ce8c6a3d Make the emulations, exec formats, coredump, NFS, and the NFS server 
into modules. By and large this commit:

- shuffles header files and ifdefs
- splits code out where necessary to be modular
- adds module glue for each of the components
- adds/replaces hooks for things that can be installed at runtime

f2976c3905 Generate syscalls entry points which can be called directly without 
going through a syscall trap.  These are currently useful for rumps.
As all the standard syscalls are not compiled into librump, mark
relevant ones with RUMP in syscalls.master.  To do e.g. a mkdir
"system call" from a rump, one would call

  rump_sys_mkdir("/dir", mode, &eval);

where the last value represents something to store errno into.

16b042cbdb from rmind@, 
- revert struct sched_param changes to restore ABI.
- instead, add 'policy' arguments to _sched_{get,set}param syscalls.
  (this is an API/ABI change.)
- correct kauth_authorize_process arguments.

while i'm here,
- don't bother to kmem_alloc for 4-byte structure.

65badb72df Version the posix_fadvise syscall and add the missing "pad" argument, 
so that it does not only work on i386 (no padding) and 64bit archs (all
args padded to 64bit).

5c71a4d49f Implementation of processor-sets, affinity and POSIX real-time extensions. 
Add schedctl(8) - a program to control scheduling of processes and threads.

Notes:
- This is supported only by SCHED_M2;
- Migration of LWP mechanism will be revisited;

7e2790cf6f Convert all the system call entry points from: 
int foo(struct lwp *l, void *v, register_t *retval)
to:
    int foo(struct lwp *l, const struct foo_args *uap, register_t *retval)
Fixup compat code to not write into 'uap' and (in some cases) to actually
pass a correctly formatted 'uap' structure with the right name to the
next routine.
A few 'compat' routines that just call standard ones have been deleted.
All the 'compat' code compiles (along with the kernels required to test
build it).
98% done by automated scripts.
