- Restructure runtime code into declarations, function
and class definitions, and initialisation code
- Rename internal functions/types to follow SWIG_Octave...
or SwigOct... naming styles
- Style/comment/whitespace cleanups
- once installed, Octave functions can never really be uninstalled
(clear -f doesn't prevent the function being called again), so
it makes no sense to install functions more than once
- this can lead to a significant speed-up of module loading times,
up to a factor of 10 for a large module loaded multiple times
- Now simply set exit function pointer "octave_exit" to _Exit.
This correctly preserves exit status when error() is called.

- _exit is a POSIX function (unistd.h), whereas _Exit is in C99 (stdlib.h)
and is therefore more likely to be supported by C++ compilers (cstdlib)

- Use call syntax instead of cmdline to choose global/noglobal load:
global: 'example;', noglobal: 'example = example;'
- All functions loaded with Octave 'autoload' command; correctly
loads .oct module and prevents segfault in Octave 3.0.5
- Functions no longer installed as global variables as well,
so global operator dispatch now only looks for functions
- Octave at-exit function created from string, not function,
so no dependence on loaded .oct files at cleanup time
- C at-exit function now immediately exits Octave (with correct
status) to prevent seg-fault due to dodgy memory cleanup
in some Octave versions
- Documentation string for module loading function

The Octave run-time allows global operators to be implemented,
e.g. op_scalar_add_X for adding a scalar and a wrapped struct X.
However it doesn't currently seem possible for these operators to
map to SWIG-wrapped functions. This is because dispatch_global_op()
looks for the operators to be installed as global variables, whereas
install_global() installs SWIG-wrapped functions as builtin functions;
the two appear to be separate symbol tables in Octave.
This patch modifies install_global() to install global operator functions
as both builtin functions and as global variables, where the value of the
global variable is a function handle to the operator function. It decides
if a function is a global operator if it begins with the prefix "op_"; this
prefix can be modified through a new command-line variable. It also always
installs the operators globally, regardless of whether the rest of the module
is being loaded globally. To accomplish this, install_global() is now always
called, but takes a bool argument specifying whether it should load symbols
globally. If a function is not a global operator, install_global() should
behave as before.
Tested that this compiles and works on Octave 3.2.4 and 3.4.0.

It's currently not possible to tell SWIG whether or not symbols should be
loaded into the global namespace by default. In fact, it's not even possible
to make the generated .oct module *not* load all symbols globally, due to a
bug in Lib/octave/octruntime.swg (line 37: "noglobal" should be "global").
It's also not possible to change the name of the symbol used to access
global variables/constants from the default "cvar".
This patch adds 3 Octave-specific command-line options:
* -global/-noglobal tell SWIG whether the generated .oct module should load
symbols into the global namespace by default. The default option is -global
to preserve existing behaviour.
* -globals <name> sets the name of the symbol used to access global
variables/constants. It is set to "cvar" by default.
These options are parsed in Source/Modules/octave.cxx, and written to the
wrapping code as the macros SWIG_global_load and SWIG_global_name.
In Lib/octave/octruntime.swg, the Octave entry point DEFUN_DLD function now
contains a expanded input argument parser, which uses the same command-line
arguments (-global/-noglobal, -globals) as can be passed to SWIG itself;
this allows the module user to change the default loading behaviour of the
module user at load time. The parser checks for non-string and unrecognised
arguments, and also checks that the argument to -globals is a valid Octave
identifier. A -help option prints a short usage message.

Fix crashing bug when compiling with MSVC.

Use SWIGRUNTIME instead of anonymous namespace to allow for correct linkage when using external runtime. Fixes infinite-recursion bug when calling director method of class whose base is in another module (since the common Director base gets a different typename in each module, per anonymous namespace).
