On x86 FreeBSD and Linux, change the way foreign symbol addresses are resolved.
They now go through a table -- effectively a new space in the core file.
Function references are resolved lazily, data references are resolved on startup
and when a .so is loaded.  The end result is that cores can be dumped that
contain references to symbols in shared libraries.  Also, the dependence of the core on addresses in the Lisp runtime is broken.

The linkage table feature is controlled by :linkage-table and LINKAGE_TABLE in C
runtime.  Several foreign symbols are now Lisp static symbols, so a cross
compile is required whether or not the new stuff is used.  I've checked in
boot4-cross-foreign-linkage.lisp that builds the compiler for linkage table; do whatever you usually do for the non-linkage table case:)  Seriously, lets start
a discussion on standardizing "cross compilation," not to mention the general
build procedure.

Support for dynamic loading in FreeBSD 4.0 and later.  This involves moving
the static space up, so a cross-compile is required to bootstrap these changes.

Added specialised port to NetBSD (1.5.2) on x86.  Since the code-base
was already cleaned up with the OpenBSD port, this doesn't require
massive changes.

Since current NetBSD is ELF-based by default, we don't make use of the
ELF feature, or in other words:  The presence of the NetBSD feature
implies ELF, since there is no support for non-ELF NetBSD.

Added specialised port to OpenBSD (2.9).  Many parts of the original
code which were previously conditionalized on :FreeBSD, are now
conditionalized on :BSD instead, with the :BSD feature now implying a
4.4BSD(lite2) derived OS.  This should make future BSD-ports easier.
FreeBSD and OpenBSD are differentiated by having either :FreeBSD or
:OpenBSD on the features list.

Currently the OpenBSD port does not have working ELF support, because
OpenBSD 2.9 is still non-ELF by default.  So don't put ELF on the
features list when building for OpenBSD, or fix the code to work
correctly in this case instead.

o Add the command line switch -dynamic-space-size for setting the size
  of the dynamic space. DYNAMIC_SPACE_SIZE now defines the maximum
  size, and when defined DEFAULT_DYNAMIC_SPACE_SIZE gives the default.

o Increase the maximum dynamic space size for Linux x86 to 1.625GB,
  with the default remaining at 512MB.

o Define the default dynamic space size for FreeBSD x86 to also be 512MB,
  with a maximum of 2GB.

Move Linux over to the new address map, giving 256M for the static and
read-only spaces; all the code branches work fine with this map on recent
Linux systems.

Reworking of the linux address map to support larger heaps,
and bringing it closer to the FreeBSD map. From Raymond Toy.

Back-out the address map changes for Linux. Only FreeBSD now uses a new
address space.

Revise the address map to better utilise the address space, allowing
larger heaps and stacks:

* There is now the potential for up to 2.75GB dynamic space on
FreeBSD, and 1.75GB on linux.  Since GENCGC statically allocates page
tables the default size is set at just 1GB.

* The Read-only and Static spaces have been increased to 256MB
allowing larger heaps to be purified. The Read-only and Static spaces
are in the same locations for both the FreeBSD and Linux ports to
avoid unnecessary binary incompatibility.

* The Control stack and Binking stack now have room for upto 128MB,
supporting deeply nested algorithms, and potentially giving room for
subdivision for thread stacks.

* There is a reserve for the FreeBSD static libraries in the event
that the FreeBSD lisp binary is dynamically linked, and the foreign
segment size for FreeBSD is now 32MB, up from just 4MB.

* There is now significantly more room for C allocated memory, roughly
128M on Linux and 224M on FreeBSD.

Increase the default read-only space size by 8MB because non-:small
cores loaded with subsystems can grow rather large.
