[ODE] changes

[Russ Smith]

recent ODE code changes:

i have reworked the build system to make it more cross-platform.
there is now a single top-level makefile and a configurator.c
program. see the INSTALL file for details.

this new system removes a number of nagging problems, such as usage of
correct header files and definition of dInfinity. please report
any problems to this mailing list.

i have not yet integrated the autoconf build system into ODE - i looked
at it, but it's complicated and wont work too well for windows users...
so it has been put aside for later.
