- 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
%template for a std::multimap generated uncompilable code unless a
%template for a std::map of the same template types was also coded up.
This patch is needed in conjunction with previous commit - 5f1fff1849Closes#64Closes#65
- 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
- this introduces a memory leak, which becomes significant for large
modules (many global variables) and many module re-loadings (e.g.
during a long-running script)
- the original motivation was to prevent double-frees on exit, but this
problem appears to have been fixed by the _Exit() hack in later commits,
and in any case is an issue only for Octave ~3.2, so it should be safe to
remove; tested by running Octave examples/test suite with Debian 3.2.4 and
built-from-source 3.2.4, 3.4.3, and 3.6.3
- 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

- New helper function Octave_begin_function writes function declaration
and installer function definition using SWIG_DEFUN macro, which in
turn uses Octave DEFUNX_DLD macro
- Can now use Octave's dynamic module loader to load functions safely
- Link documentation of public wrapping functions through DEFUNX_DLD

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.
