MSVC patch: export symbols in macros

[Michael Goffioul]

Hi,

I'd like to propose the (quite large) attached patch. The idea is to 
avoid hardcoding
OCTAVE_API in various macros used in liboctave, and put this as an 
additional
argument to the macros. This provides a more flexible system where 
macros can
be used easily outside of liboctave. This problem popped up when trying 
to compile
support for fixed point numbers from octave-forge: with OCTAVE_API hardcoded
in the macros, it's impossible to compile it.

Michael.
