8ecb3577d8 Add sysentvec->sv_fixlimits() hook so that we can catch cases on 64 bit
systems where the data/stack/etc limits are too big for a 32 bit process.

Move the 5 or so identical instances of ELF_RTLD_ADDR() into imgact_elf.c.

Supply an ia32_fixlimits function.  Export the clip/default values to
sysctl under the compat.ia32 heirarchy.

Have mmap(0, ...) respect the current p->p_limits[RLIMIT_DATA].rlim_max
value rather than the sysctl tweakable variable.  This allows mmap to
place mappings at sensible locations when limits have been reduced.

Have the imgact_elf.c ld-elf.so.1 placement algorithm use the same
method as mmap(0, ...) now does.

Note that we cannot remove all references to the sysctl tweakable
maxdsiz etc variables because /etc/login.conf specifies a datasize
of 'unlimited'.  And that causes exec etc to fail since it can no
longer find space to mmap things.

ca02557604 change CLASS depending upon __ELF_WORD_SIZE. This is necessary if
someone wants to try to run 32bit binaries on sparc64.

a3b8e6c9c7 Move the definition of ElfN_Hashelt to common headers. The only platform
which has a different definition for this is alpha.

489876bc4d Add skeleton machine dependent headers and c files for a port of freebsd
to a new architecture.  This is the base of the sparc64 port, but contains
limited machine dependent code, and can be used a base for ports.  Included
are:
- standard machine dependent headers, tweaked for a 64 bit, big endian
  architecture, including empty versions of all the machine dependent
  structures
- a machine independent atomic.h, which can be used until a port has
  support for interrupts and the operations really need to be atomic
- stub versions of all the machine dependent functions, which panic
  when called and print out the name of the function that needs to
  be implemented.  functions which are normally in assembly files are
  not included, but this should reduce the number of different undefined
  references on the first few compiles from hundreds to 5 or 6
Given minimal startup code and console support it should be trivial to
make this compile and run the first few sysinits on almost any architecture.
