Update haad-dm branch to haad-dm-base2.

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

Add PaX ASLR (Address Space Layout Randomization) [from elad and myself]

For regular (non PIE) executables randomization is enabled for:
    1. The data segment
    2. The stack

For PIE executables(*) randomization is enabled for:
    1. The program itself
    2. All shared libraries
    3. The data segment
    4. The stack

(*) To generate a PIE executable:
    - compile everything with -fPIC
    - link with -shared-libgcc -Wl,-pie

This feature is experimental, and might change. To use selectively add
    options PAX_ASLR=0
in your kernel.

Currently we are using 12 bits for the stack, program, and data segment and
16 or 24 bits for mmap, depending on __LP64__.

Remove the "struct lwp *" argument from all VFS and VOP interfaces.
The general trend is to remove it from all kernel interfaces and

Use an elf note to handle pax arguments. This is a temporary solution to
avoid wasting OS flag bits. In the future we'll probably use fileassoc to
achieve this (once there is a way to make fileassoc persistent) or in the
shorter term libelf, so that we can add and remove the note on demand instead
of burning bits on each binary. Of course since this is a tool, this means
that we'll need to think about how to handle libelf...

Change the way that emulations locate files within the emulation root to
  avoid having to allocate space in the 'stackgap'
  - which is very LWP unfriendly.
The additional code for non-emulation namei() is trivial, the reduction for
  the emulations is massive.
The vnode for a processes emulation root is saved in the cwdi structure
  during process exec.
If the emulation root the TRYEMULROOT flag are set, namei() will do an initial
  search for absolute pathnames in the emulation root, if that fails it will
  retry from the normal root.
".." at the emulation root will always go to the real root, even in the middle
  of paths and when expanding symlinks.
Absolute symlinks found using absolute paths in the emulation root will be
  relative to the emulation root (so /usr/lib/xxx.so -> /lib/xxx.so links
  inside the emulation root don't need changing).
If the root of the emulation would be returned (for an emulation lookup), then
  the real root is returned instead (matching the behaviour of emul_lookup,
  but being a cheap comparison here) so that programs that scan "../.."
  looking for the root dircetory don't loop forever.
The target for symbolic links is no longer mangled (it used to get the
  CHECK_ALT_xxx() treatment, so could get /emul/xxx prepended).
CHECK_ALT_xxx() are no more. Most of the change is deleting them, and adding
  TRYEMULROOT to the flags to NDINIT().
A lot of the emulation system call stubs could now be deleted.

Fix some things regarding COMPAT_NETBSD32 and limits/VM addresses.
* For sparc64 and amd64, define *SIZ32 VM constants.
* Add a new function pointer to struct emul, pointing at a function
  that will return the default VM map address. The default function
  is uvm_map_defaultaddr, which just uses the VM_DEFAULT_ADDRESS
  macro. This gives emulations control over the default map address,
  and allows things to be mapped at the right address (in 32bit range)
  for COMPAT_NETBSD32.
* Add code to adjust the data and stack limits when a COMPAT_NETBSD32
  or COMPAT_SVR4_32 binary is executed.
* Don't use USRSTACK in kern_resource.c, use p_vmspace->vm_minsaddr
  instead (emulations might have set it differently)
* Since this changes struct emul, bump kernel version to 3.99.2
Tested on amd64, compile-tested on sparc64.

we could fix the code in those two places to read section-by-section instead
of all the sections at once as it does now, if we really felt like it.

VM_DEFAULT_ADDRESS from elf*_makecmds to elf*_load_file.  In load_file,
actually determine ahead of time how much space will be needed and pass
that to VM_DEFAULT_ADDRESS.  Now we have a relatistic starting address
so we can do the loading of psections normally with no extra topdown
code in load_psection.  Also, if there is a gap in betweeen psections
zero map an inaccessible region between (just like ld.elf_so does) to
avoid inadvertant mmaps in the gap.

Introduce "top down" memory management for mmap()ed allocations.  This
means that the dynamic linker gets mapped in at the top of available
user virtual memory (typically just below the stack), shared libraries
get mapped downwards from that point, and calls to mmap() that don't
specify a preferred address will get mapped in below those.

This means that the heap and the mmap()ed allocations will grow
towards each other, allowing one or the other to grow larger than
before.  Previously, the heap was limited to MAXDSIZ by the placement
of the dynamic linker (and the process's rlimits) and the space
available to mmap was hobbled by this reservation.

This is currently only enabled via an *option* for the i386 platform
(though other platforms are expected to follow).  Add "options
USE_TOPDOWN_VM" to your kernel config file, rerun config, and rebuild
your kernel to take advantage of this.

Note that the pmap_prefer() interface has not yet been modified to
play nicely with this, so those platforms require a bit more work
(most notably the sparc) before they can use this new memory
arrangement.

This change also introduces a VM_DEFAULT_ADDRESS() macro that picks
the appropriate default address based on the size of the allocation or
the size of the process's text segment accordingly.  Several drivers
and the SYSV SHM address assignment were changed to use this instead
of each one picking their own "default".

Two small changes to the ELF exec code:

(1) ELFNAME(load_file)() now takes a pointer to the entry point
offset, instead of taking a pointer to the entry point itself.  This
allows proper adjustment of the ultimate entry point at a higher level
if the object containing the entry point is moved before the exec is
finished.

(2) Introduce VMCMD_FIXED, which means the address at which a given
vmcmd describes a mapping is fixed (ie, should not be moved).  Don't
set this for entries pertaining to ld.so.

Also some minor comment/whitespace tweaks.

Define ELF32_EHDR_FLAGS_OK()/ELF64_EHDR_FLAGS_OK() and use it
as an added measure to make sure that we can execute a binary.
These default to (1) if elf_machdep.h does not override them.

On Sun2, ELF32_EHDR_FLAGS_OK() checks for the presense of EF_M68000,
since the 68010 cannot run binaries for the 68020-and-up.

- Add a new vnode flag VEXECMAP, which indicates that a vnode has
  executable mappings.  Stop overloading VTEXT for this purpose (VTEXT
  also has another meaning).
- Rename vn_marktext() to vn_markexec(), and use it when executable
  mappings of a vnode are established.
- In places where we want to set VTEXT, set it in v_flag directly, rather
  than making a function call to do this (it no longer makes sense to
  use a function call, since we no longer overload VTEXT with VEXECMAP's
  meaning).

VEXECMAP suggested by Chuq Silvers.

  e_syscall_intern, which is called at key places in the kernel.  This can be
  used to set a MD syscall handler pointer.  This obsoletes and replaces the
  *_HAS_SEPARATED_SYSCALL flags.
* __HAVE_MINIMAL_EMUL.  If this is defined, certain (deprecated) elements in
  struct emul are omitted.

restructure struct emul and execsw, in preparation to make emulations LKMable:
* move all exec-type specific information from struct emul to execsw[] and
  provide single struct emul per emulation
* elf:
  - kern/exec_elf32.c:probe_funcs[] is gone, execsw[] how has one entry
    per emulation and contains pointer to respective probe function
  - interp is allocated via MALLOC() rather than on stack
  - elf_args structure is allocated via MALLOC() rather than malloc()
* ecoff: the per-emulation hooks moved from alpha and mips specific code
  to OSF1 and Ultrix compat code as appropriate, execsw[] has one entry per
  emulation supporting ecoff with appropriate probe function
* the makecmds/probe functions don't set emulation, pointer to emulation is
  part of appropriate execsw[] entry
* constify couple of structures

Elf32 fixes for mips shared libraries:

 * handle interpreters with nonzero virtual address of entry-point:
   subtract p_vaddr from computed entrypoint, as the mips elf exec did.

 * Add #ifdef ELF_INTERP_NON_RELOCATABLE/#endif around the code
   that tries to choose a `good' address at which to load an interpreter,
   if none was set by the emul probe  function.
   (the address chosen could be improved to avoid  fragmenting the
    process virtual address space).

 * define ELF_INTERP_NON_RELOCATABLE in machine/elf_machdep.h for mips CPUs,
   which currently use a GNU-derived ld.so.

ELF_INTERP_NON_RELOCATABLE is not necessary for native NetBSD/alpha ELF
binaries. It may be required for GNU-derived ELF dynamic loaders (Linux/i386?)

deal more sanely with ELF binaries with only a single program header
section.  Patch come up with by Bob Baron <rvb+@cs.cmu.edu> and myself.
This entire bit of code (the code which sets daddr/dsize and taddr/tsize)
is very bogus, but it's not clear what the 'right' way to fix it is
and this patch fixes a problem preventing some ELF executables from
being run.

replace ELF_ALIGN with ELF_TRUNC (round to lower alignment boundary) and
ELF_ROUND (round to higher alignment boundary), and use them properly.
Also, change a bit of code in elf_load_psection to use the next ELF_ROUND
macro.  This fixes a bug found by Robert Baron <rvb+@cs.cmu.edu> where
elf_load_psection, if given a properly aligned address at which to load
the section, would round actually load it at the next highest alignment
boundary.

when loading interpreter: check its vnode type, check its mount point
for NOEXEC and NOSUID, and make sure the interpreter file is executable.
The mount point checks are done because, even though the interpreter
is not the program being 'executed', code from the interpreter is being
executed, and so the mount point's flags should be respected.
